Going against the flow…
You can easily slip into the wrong frame of mind. All around you hear doom and
gloom and even the Chancellor warning of “tough times ahead” but there is always
business to be done, especially in our industry.
Water and drainage will always be around and we must visualise it getting
much better with more jobs on the horizon.
For instance, one project that is coming along is that Thames Water is looking
to spend some £600M undertaking the biggest project in the water industry since
privatisation in 1989.
They have awarded the contact to a consortium of construction and engineering
firms that will start work shortly on a 4.3mile tunnel designed to divert half the raw
sewage that is dumped into the capital’s river.
The Abbey Mills pumping station which takes sewage from north and east
London to the sewage treatment works in Beckton, East London is regularly overwhelmed
in heavy rains.
Rather than allowing untreated sewage to seep up through the manholes and
gullies, the overflows are released untreated into the River Lee, a tributary of the Thames.
The tunnel will be as wide as three double-decker buses and Thames will eventually spend
another £220million upgrading the Beckton plant so it can take the increased load.
Thames is also looking to build a second more complex tunnel basically
following the path of the Thames for 20 miles through the heart of the capital. It will
intercept 34 sewage overflow points and like the Lee tunnel, take the sewage to Beckton.
The project will require the permission of 13 councils and cost more that £2 billion. So
although other industries may well be in the doldrums, it would seem that water is on the
up and up…
As always if you have any interesting articles or a
point of view please feel free to contact the editor by email,
olivia@pse.co.uk and just to let you know the next edition
will be out in the middle of June 2010.

New digital
chlorine
dioxide testing
from Palintest
P
alintest Ltd, a leading water analysis technology company, has
developed a completely new method for testing Chlorine Dioxide levels
in water. The ChlordioXense provides accurate testing without relying
on subjective analysis for results. The instrument eliminates the potential for
user error giving precise, consistent results whatever the operator’s level of
experience.
Developed from the successful electrochemical sensing technology in their
ChloroSense digital chlorine sensor (now EPA approved), the ChlordioXense
is very easy to operate. Simply insert a disposable electrode along with the
water sample and close the lid to start a test. The instrument works for a wide
range of concentrations, from 0.02 - 50 mg/l, with sample temperatures up
to 40 degrees Celsius, with results given clearly on the LCD screen in less
than a minute.
Compared to the US EPA-approved Lissamine Green test method, the
ChlordioXense gives accurate results with greater consistency. This means
that the time taken and the training needed to get results is significantly
reduced, benefiting a wide range of applications from food processing to
paper mills and building services.
The unit stores up to 500 results in its on-board memory, and can be
connected by USB to a PC for simple downloading. Powered by AA batteries
and weighing less than 1kg, it is truly portable and offers effortless Chlorine
Dioxide measurement for any situation.

Landia to the
rescue in
hospital
emergency
P
ump breakdowns and a six-week waiting time for new parts left a
hospital in Shropshire with a costly and difficult effluent problem until
Landia stepped in to help.
Nuffield Health Shrewsbury Hospital were let down by the failure of one
pump, followed almost immediately by the second – only to be told by
their supplier that replacement parts needed for repair would take at least
six weeks.
In the meantime, the Nuffield maintenance team were forced to bring in
two tankers per day to remove the effluent - at a cost of well over £600
per load. Brian Forster, Resident Engineer for Norland Managed Services,
commented: “We felt very let down, but Landia restored our faith by
rolling up their sleeves and immediately getting stuck in to help find a
quick yet long term economic solution”.
Landia’s rapid turnaround saw the installation of a 5.5kW MPTK Cutter
Pump with external knife system, which can handle hospital waste with a
high content of solids, without breaking down.
Brian Forster added: “Not only do we now have a first class pumping
system in place, but importantly we have the peace of mind of Landia’s
fast turnaround and back service up to help us out if necessary”.
As well as designing in the interface for the retrofit to the existing pumping
system, Landia also fitted a submersible well pump for Nuffield Health
Shrewsbury Hospital to keep the dry well clear of water.

EnviroChamber the recycled composite chamber solution
PDS-Plc are an established company and have
for a number of years been supplying
drainage and associated products to the
highways authorities, building contractors
and local councils.
PDS-Plc also offer as part of the customer
service a design facility to ensure that the
correct product is supplied to meet the design
criteria and it is fit for purpose.
To compliment the existing range of products
and to allow the company to move into areas
which service the utility companies such as
gas, telephone and especially the water
industry, PDS-Plc have extended their range
of products to include various sizes of one
piece moulded under ground chamber
sections.
After listening to, and working with, four UK
water companies and their contractors, the
chamber sections were designed to be made
as a one-piece moulding, are lighter than
concrete and stronger than concrete and most
importantly cost effective when compared with
traditional materials and meet all of the
existing future specifications.
They also had to overcome most or all of the
health and safety problems associated with
traditional chamber sections. The most
important being they could be handled by one
6 WSW 2010
person except for the very largest of the
section which is 33kg, this heavier section
would still only require a two-man lift and no
mechanical handling systems. This would
result in a quicker installation time and
improved labour efficiency.
As each section is lighter to transport, more
chambers can be carried on each wagon,
therefore there will be fewer trips and the end
result is a lower carbon footprint and reduced
transport costs.
EnviroChambers sections are made using the
compression moulding technique at two
manufacturing plants in the UK both sited in
the north west of England.
The chamber sections are made from 100%
recycled material obtained purely from UK
sources from the post consumer waste stream.
This waste would normally end up in landfill
sites or incinerators and can, unlike
traditional materials at the end of its useful
life, be recycled to make new products.
The one-piece moulded design gives them
exceptional compressive strength and rigidity
and therefore they are not susceptible to
breaking either during installation or during
transportation like traditionally made concrete
sections.
This results in a cost saving to the end user by
not having to budget for breakages by
ordering extra products and additional
transport.
The material used is impervious to moisture
and therefore not susceptible to frost damage
and crumbling when in use.
All chambers throughout the different size
ranges have a positive interlocking system to
locate the sections one on top of the other and
prevent any movement of the individual
sections when finishing the chamber with
backfill. They also incorporate a positive
location for any of the cast iron or composite
covers used in this industry.

Innovation celebrated in construction products industry
S
aint-Gobain PAM UK has been
recognised for its innovative Hydraulic
Pipe Unloading Beam in the
Construction Products Association’s 2009
edition of Construction Products Innovation
and Achievement (CPIA).
The Unloading Beams achievement in the
category of Health, Safety and Security is
one of only 24 products nationwide, to be
chosen for last year’s publication, which
annually showcases the most innovative
products and processes created by the
construction products industry during the
last twelve months or so.
Commenting on the achievement, Simon
Storer, Communications and External Affairs
Director, for the Construction Products
Association said: “We are delighted that
the construction products industry has once
again shown an enormous desire to
introduce a variety of new and exciting
solutions. Despite the economic downturn in
the UK, and the construction industry
suffering more than most, you only need
look at the products and processes
showcased in CPIA to highlight the huge
input the industry is making towards
change.
The industry has not always been good at
trumpeting its own achievements. However,

publication. Our Unloading Beam will bring
enormous benefits to the construction
industry by optimising safety in the pipe
unloading process on sites across the UK.
The beam is a ground-breaking means of
unloading pipes as it completely removes
the need to work at height and also
eliminates the expense and inconvenience of
crane hire. It is very important that our
industry recognises and showcases
innovation and we are grateful that CPIA
2009 does this.”
It is the fi rst premium-effi ciency pump in the world.

Our greater energy saving gives you:
The ABS EffeX range of submersible sewage pumps
has built-in IE3 premium-effi ciency motors in accordance
with IEC60034-30 to optimise motor effi ciency.
The main benefi t of this is the highest effi ciency
available without any impact on the risk of increased
blockage often associated with hydraulic effi ciency.
Moreover, the ABS EffeX range boosts impeller
design to the next level and achieves some of the
highest hydraulic effi ciencies in the market, while still
maintaining a minimum 75 mm free solid passage.
CPIA demonstrates how the construction
products industry is continuously developing
and improving by creating innovative
solutions which make a significant impact to
all aspects of construction”.
The 24 entries in CPIA are under four key
headings; Energy and Carbon Saving;
Health, Safety and Security; Improvements
in Site Safety; and Resource Efficiency. By
delivering these efficiencies, these new
ideas bring a range of benefits to everyone
including clients and end users, company
employees and especially the environment
we live in.
The products featured in the publication
cover a wide range and include processes
designed to save energy and reduce
emissions, providing safer operations on
site for employees and contractors and
provide a full sustainability appraisal of
manufacturing operations. This creative and
innovative approach is not confined just to a
select few in one or two sectors, but can be
seen as a key driver for an industry that is
continuously improving and constantly
changing.
Andy Burnham, Supply Chain and
Distribution Manager from Saint-Gobain
PAM UK added, “We are very pleased to
have been chosen for last year’s CPIA

Sewage treatment works Struvite
T
hames Water Utilities sewage treatment
works at Stanstead Abbotts, Hertfordshire
handles all the sewage from the conurbation
of Harlow and surrounding areas. The sewage
works dispose of cake, a by-product, either by
drying and then incinerating to produce green
energy, or, as in the case of Beckton and
Crossness, with the remainder of the sewage
treatment works mixing the cake with straw for
use as fertiliser. Prior to drying, liquid is removed
from the cake with a Klampress using a belt and
central drum to squeeze the substance.
Struvite, a hard crystalline scale consisting of
mainly magnesium and ammonium phosphate,
built-up on the drum and belt, making removal
with conventional high pressure washing

impossible. The struvite caused the holes on the
belt of the Klampress to block, resulting in the
press becoming less efficient.
High-pressure water washing was unable to
remove the struvite and the use of chemicals was
rejected, as the fertiliser by-product is used in the
farming industry. Estimated costs, from the
manufacturer of the system, for removing the
two-ton drum and acid cleaning were given at
around £7,000.
Following a site survey by an engineer,
Scalewatcher ENiGMA systems were installed
on the main feed and the wash water. Since
then, employees of Thames Water Utilities,
carrying out high pressure water cleaning of the
Klampress have reported to Stephen Payne,
Area Support Engineer, that the struvite is much
softer and far easier to remove from both the
drum and belt.
Commenting, Stephen Payne, says: “The cost of
sending the drum back to the manufacturers was
prohibitive and the Scalewatcher ENiGMA
system has proved a cost effective and
environmental solution to the problem”.
Such has been the success of the ScaleWatcher
Enigma, Thames Water Utilities is planning to
purchase further units for the other two
Klampresses located at the site

“FBA has been used successfully in the US for
a number of years for the treatment of
hydrocarbons and glycols. It’s just one of the
ways in which we’re making environmental
advances to open up entirely new applications.
For instance, when we were in Leeds at the
European Biosolids Conference last week, we

Says Steve Wilding, Area Sales Manager, ABB
UK instrumentation: "ABB has had a longstanding
relationship with Thames Water,
spanning over 20 years. During this time, we
have established a good reputation for the
accuracy of our flow measurement equipment.
Our new agreement with Thames Water is an
exciting opportunity for us to demonstrate how
our equipment can help the company to realise
new levels of measurement accuracy across a
broader range of parameters."
The flow instrumentation will be primarily used
on Thames Water's large water and wastewater
treatment works pipelines ranging 50mm-2.2m
and out on the district metered areas to help
identify and counteract leakages in its mains.
The Pressure transmitters will be used to measure
pressure surges within the network, and critical
pressures at pumping stations and treatment
process plants.
Thames Water is the largest water & wastewater

FPSO’s fresh water supply from Eimco
Water Technologies
imco Water Technologies have been awarded a significant order by BP to
supply and install a fresh water manufacturing plant on the FPSO (Floating
Production, Storage and Offloading vessel) Schiehallion.
Located in the Schiehallion oil field in the North East Atlantic Ocean to the west
of the Shetland Islands, the high operating costs for the FPSO’s existing fresh
water making plant led BP to evaluate the payback of replacing the old system
with the latest development in Reverse Osmosis (RO) Technology, as designed
by Eimco Water Technologies.
The new design had to meet very tight transportation criteria, including the
need for it to fit into the existing footprint to minimise pipe-work and
modification during installation.
The RO system replaces traditional methodologies and components with latest
developments that include maintenance-free Axial Piston Pumps, guaranteed
for three years, which have also significantly reduced the amount of space
required.
By introducing a new Proportional Chemical Dosing Technique, Eimco Water
Technologies is expected to also reduce chemical refill frequency from a daily
task to just once every 50 days, eliminating the need to dilute chemicals.
A PLC/HMI Interface allows the plant to operate automatically and the
installation of the latest membrane technology should save on costs by reducing
the actual number of membranes required.
The lifetime of the RO
membrane is expected to
greatly increase by the
utilisation of new advanced
filters that eliminate the need
for sand cartridge filters and
ensure a high quality feed

Royal train yard recovering thanks to Onsite
Andy Buckley Civil Asset Engineer with Anglian Water observes the 900 mm diameter Premier
Pipe liner as it is being installed.
he Royal Train Yard at Wolverton Rail Works in
Milton Keynes was aquired by housing
developer Willmott Dixon in order to create
300 new homes. The project was to tackle a very
complex refurbishment of the 200 year-old
building.
There was a requirement to stabilise an area of
potentially unstable ground under the existing
building which investigations showed carried a
900mm diameter surface water sewer. The sewer
ran at a depth of 14m below the historic Grade II
listed building and the Grand Union Canal
connection London to Birmingham. The sewer was
the responsibility of Anglian Water.
Historical drawings showed the sewer running in a
straight line between two manholes for a distance
of just over 100m. With this information of the
location of the sewer, Willmott Dixon’s engineers
drilled a bore hole which was pumped full of
concrete to stabilise the ground below. In the event,
the drawing was found not to be complete. The
sewer had in fact been constructed, not in a straight
line as shown on the drawing, but as a long slow
bend with part of its course running directly below
where the bore hole operation had taken place.
This meant that the bore hole had been drilled

directly into the sewer which had subsequently
been completely filled with concrete.
Once aware of the situation Willmott Dixon, with
Anglian Water’s approval, attempted to remove the
concrete using high pressure jetting. Unfortunately
this proved ineffective.
Subsequent attempts were made to remove the
concrete using man-entry methods and water
lances. Whilst this achieved the removal of some
2m of concrete, the operation was abandoned on
health and safety grounds because the pipe
structure was compromised by cracking found near
to where it was believed the bore hole had passed
through it.

working which would enable crews to work within
the pipe whilst remaining fully protected during the
cutting operations.
The method involved installing a series of structural
CIPP repair patches inside the pipe up to the face of
the concrete. The concrete excavation team could
then work safely within the ‘patched’, and therefore
supported, area of the pipe whilst further concrete
was removed. A new patch was installed after
every 0.5 m of concrete was removed, enabling
safe working to continue.
As the operation progressed a constant appraisal
of procedures was carried out with new ideas and
suggestions being put forward all the time. Such
suggestions included the installation of a temporary
support heading where the concrete had been
poured into the pipe. After just seven days the
teams working within the pipe had completely
removed the 8m long concrete obstruction.
Subsequently, and to ensure the long term structural
integrity of the pipe particularly around the
damaged area caused by the bore hole, Anglian
Water accepted OnSite’s proposal to fully line the
damaged area using its structural Premier-Pipe
CIPP lining system.
Whilst an alternative GRP lining method had been
considered it was ultimately rejected by Anglian
Water on the grounds that, once installed, the
sewer pipe flow capacity could be insufficient with
the loss of so much cross sectional area, which
concerned Anglian Water’s engineers.

The upstream end of the twin 1,350 mm
diameter culverts being rehabilitated.
A
growth area for the use of Insituform
Technologies Ltd. (ITL)s lining products
has been that of culvert rehabilitation.
A recent project in Ireland demonstrated just
how effective renovation of existing systems
can be even in difficult-to-access
circumstances.
The project as part of the Ballyogan Landfill
Stage 2 Capping contract. The culvert
rehabilitation project was designated as the
Ballyogan Landfill Site Carrickmines Dublin
18 works. The client was Dun Laoghaire
Rathdown County Council with RPS
Consulting Engineers acting as its
engineering consultant. The main contractor
for the project was Priority Construction, and

Techniques, a subsidiary of ITL (IET).
The Ballyogan Landfill and Recycling Park
(BRP) surrounding area is characterised by a
mixture of agricultural, recreational,
residential, commercial and industrial land
use. The total site area is approximately 62
hectares, 43 of which were used for landfill.
The BRP currently occupies approximately 11
hectares. The remaining area consists of the
landfill site entrance and service roads, site
compound, landfill gas combustion plant,
methane stripping plant and other services.
The permanent cap is in place on one part of
the landfill. This area is defined as the Stage
1 Area. The remainder of the area is
currently being capped under the Stage 2
Capping Contract, the contract under which
the culvert lining sub-contract is designated.
The installation site was beside the Arklow
Carrickmines 220kV electricity substation.
As part of these works a Strategic
Improvement Plan (SIP) was carried out for
the landfill which highlighted the fact that the
twin 1,350mm diameter culverts were at a
risk of structural failure due to their location
and age, and required rehabilitation.
The twin culverts, which extend through the
body of the landfill site, convey the Ballyogan
Stream through the landfill.
After careful consideration of the options
available it was decided that rehabilitation
would be most efficiently and cost effectively
achieved by using two single shot
installations, each 271m long, using curedin-place
pipe (CIPP) lining technology, a form
of lining in which IET specialises.
Before beginning the installation of
Insituform® CIPP, the culverts were cleaned

and CCTV surveys were undertaken in order
to assess the extent of any existing damage to
the pipe structure. The closed-circuit
television report detailed a number of
structural faults along the length of the
culverts which ranged from Grade 1 to
Grade 4 status. Whilst it was thought that
these cracks did not pose a short-term risk to
the structural integrity of the culverts, it was
considered prudent to take early remedial
action to ensure that the culverts did not
deteriorate any further and that they remain
structurally sound into the future.
One of the main obstacles to a simple
installation solution was the proximity of the
installation site to the Arklow Carrickmines
220 kV electricity substation. Power lines
from the substation are known to pass directly

over the inlet of the river culverts. This meant
that there was a maximum permissible
machinery reach and height restriction of 4.5
m. Although a heavy duty scaffolding
arrangement could be constructed at the liner
launch site, no crane could be used to feed
the impregnated liner to the scaffold.
In all, the lining works were scheduled as a
three week programme. Once the site was
prepared and the liners were ready to invert,
both of the liner installations took just three
days each to complete - including installation
and hot water curing.
As previously mentioned, working in a river
environment meant the flow had to be
diverted on a continuous basis.
Paul Smyth, Director of Insituform
Environmental Techniques said: “In this
project, we have carried out the largest CIPP
lining job in Ireland to date in very difficult
conditions while completing the work both on
time and on budget. The close co-operation
between the main contractor, Priority
Construction and the project manager, RPS,
resulted in a successful outcome of the project
and complete client satisfaction.”
For ITL, John Beech, Business Development
Manager, commented: “These installations
were not exactly ‘run-of-the-mill’ jobs. Access
was tricky, particularly given the proximity of
the substation. The lining operations
themselves went very well, even with the
logistics challenges of getting materials and
supplies to relatively remote locations. It was
a job well done.”

Rotork valve actuators assist high-tech upgrade
Rotork IQT actuators installed on new pipework in the
chambers between the membrane plants, operating the
sewage inlet and outlet, air, sodium hypochlorite, wash
water and permeate valves.
T
he Wessex Water sewage treatment works
at Swanage utilises state-of-the-art
membrane bioreactor technology to
produce high quality effluent that exceeds EU
standards and is cleaner than the sea into which
it is discharged.
Now nearing completion, a major plant
upgrade at the site is introducing automation
and energy saving measures, whilst increasing
the size of the membrane treatment plant to
provide spare capacity for future demand.
Central to the upgrade, Profibus networkenabled
Rotork IQT intelligent electric actuators
have been installed to operate butterfly and plug
valves on new pipework throughout the plant.
Swanage STW treats sewage for a population of
around 10,000 which can more than double
when the area is busy with holidaymakers.
Following preliminary screening and grit
removal, sewage enters Kubota membrane
plants installed in six large tanks for biological
treatment and disinfection. The pores in the
membranes are so small that they can prevent
microscopic bacteria and viruses from passing
through. The upgrade involves increasing the
number of membrane packs in each tank to
thirty-six, thus considerably increasing the

treatment capacity without exceeding the
confines of the existing works’ footprint.
Automation of the treatment process also
enables it to run with increased efficiency and
reduced energy consumption.
On each of the membrane plants, the Rotork IQT
actuators operate inlet isolation and outlet
modulating valves for the sewage, together with
air, sodium hypochlorite and wash water
injection valves. Additional IQT actuators control
the permeate isolation valves used for
automated sequential flushing to maintain
membrane efficiency. In total, fifty-one actuators
are installed on each tank to provide automatic
sequencing of the sewage treatment, membrane
cleaning and backwashing processes.
Fourteen Profibus-DP two-wire networks link the
actuators to PLCs in the site’s central MCC. These
are controlled by a PLC and SCADA system
written by Wessex Water’s in-house Automation
Team. The control PLC is a twin CPU
configuration, with one dedicated to the control
and monitoring of more than 300 actuators,
whilst the other runs the complex automation
process, resulting in the collection of control,
status and full diagnostic data from each
actuator, without any PLC speed or memory

locally at the valve or nearby HMI, on the site
SCADA system and at the regional operation
centre at Bath. Remote diagnosis is a cost
effective method of maintenance and service
because the right operational staff can be sent to
site when required.
With the high level of process automation
enabled by the Rotork actuators, come the
added benefits of process integrity, audit ability
and highly reliable and accurate process
control. Running costs are expected to reduce
due to more effective control of the plant, saving
electrical power, cleaning agents and water. The
effective use of Profibus technology has allowed
significant installation savings in cabling,
terminations, PLC hardware and labour.
The Damar Group is the principal contractor for
mechanical and electrical installation at the
Swanage upgrade project, including the on-site
fabrication and installation of pipework and
actuated valves. The project manager is Wessex
Engineering and Construction Services and the
design consultant is Mott MacDonald. The
Rotork actuators have been supplied in
accordance with the framework agreement that
the company holds with Wessex Water.

Manchester Airport run-off measured perfectly by Pulsar
P
ulsar Process Measurement have supplied a
non-contacting ultrasonic open channel
flow measurement system featuring their
DUET transducer array to give excellent
measurement accuracy in the airport’s critical
22 WSW 2010
API hydrocarbon separation
unit. Pulsar’s FlowCERT
system featuring the DUET
transducer has achieved
Class 1 MCERTs certification.
Surface water runoff in an
area as large as a major
airport is considerable, and
in certain areas may be
mixed with aviation fuel, oil
and other contaminants, so it
has to be treated in the same
way as any other industrial
effluent before it can be
discharged. That means
separation, treatment and
measurement of the final
effluent flow, which is where
Pulsar comes in.
Pulsar supplied a v-notch
weir plate along with a DUET
transducer array and
FlowCERT control unit to
measure effluent flow through
an open channel. As can be
seen in the picture, the
channel was in an exposed
position, where solar
radiation can be a significant
factor affecting the accuracy
of the measurement. The vnotch
weir plate was sized for
a maximum flow rate of 25
litres per second, although
the actual flow can be very
small indeed in dry periods of
the year. It is vital that the measurement remains
reliable and accurate. The measurement of this
type of application is particularly difficult; the
ultrasonic technique is based on the
measurement of the time taken for an echo to
return to the face of a transducer, which is in turn
dependent on the speed of sound. The speed of
sound in air varies with air density, which is
affected by air temperature. If the measurement
device does not compensate quickly and
accurately, errors are introduced into the result.
In this case, because the head varies by around
200mm between high flow and zero, it is crucial
that the measurement is accurate and repeatable
right down to the very lowest flows, and records
a genuine zero when there is no flow at all.
DUET is perfect for this type of application,
consisting as it does of an array of two
transducers that fire ultrasonic pulses
simultaneously, which are then received at the
lower transducer only. The FlowCERT controller
then compares the two returning echoes. The two
transducers are mounted on a heavy frame and
the separation of the two transducers is a fixed
distance, so any changes in the measured
distance when comparing the two ultrasonic
pulses must be down to variations in the speed of
sound. This strategy allows the FlowCERT
controller to compensate dynamically and
accurately for these variances, applying that
compensation to the flow measurement. Under
MCERTs tests, this unique system has allowed
FlowCERT and DUET to achieve industry-leading
total error levels of only 0.037%, even under the
new, stringent, solar radiation test.
As Mark Stewart, the Airport’s Water Services
Engineer in charge of the project, put it: ‘We
were very pleased with the way that Pulsar
responded to the project brief, and have been
delighted with the performance of the DUET.
We’re confident about the measurement, so we
know we are submitting exactly the right figures
to the EA. We’re now in the process of
standardising on Pulsar equipment for all our
flow and level measurement applications’.

Fixed-Film role in Catalonia for Eimco Water Technologies
E
Integrated Fixed-Film Activated Sludge system
imco Water Technologies has won a £5M
contract with FCC Construcción y Aqualia
Infraestructuras to upgrade the existing
Terrassa Wastewater Treatment Plant, just north
of Barcelona, owned by the Catalan Water
Agency (ACA), which is the public entity of the
Government of Catalonia assigned to the
Department of the Environment and Housing.
The installation includes an IFAS (Integrated
Fixed-Film Activated Sludge) system that will be
used to improve the plant effluent quality,
remove nutrients and increase the capacity of the
existing plant by introducing extra biomass
growing surface into the Bioreactors. This has
removed the need, cost and disruption of civil
construction, yet has increased the capacity of
the plant by 25% (from 60.000 m3/day to
75.000 m3/day).
This additional surface area comes from a
number of polypropylene Biotextiles, installed in
stainless steel structures that will be submerged
in the fine bubble aerated zones of the
Bioreactors.
Due to the limited space available in the existing
plant, the Terrassa project required specially
designed sliding steel supports that allow the
IFAS cages to be easily moved inside the tanks
for maintenance purposes.
EIMCO Water Technologies is also installing
three new secondary suction clarifiers (43m
diameter) at Terrassa to improve the secondary
settlement to help achieve better effluent
parameters.
EIMCO Water Technologies provided FCC
Construcción y Aqualia Infraestructuras with a
full real scale module to show how the
polypropylene Biotextiles would operate and to
allow oxygen transfer tests, as well as a small
pilot Biotextile cage to run performance trials,
both under the Catalan Water Agency (ACA)
assignment and supervision.

F
rom 1 April 2010 the storage of fuel oil in
quantities above 200 litres in Scotland will
require secondary containment such as a
bund or drip tray. Failure to do so could result in
a fine of up to £40,000.
The “Water Environment (Oil Storage) (Scotland)
Regulations 2006” become mandatory on that
date having been originally introduced in
October 2006.
Operating at the forefront of tank design and
manufacturing innovation, Aberdeen-based
Balmoral Tanks understands the UK fuel oil
storage market like few others. SEPA’s regulatory
deadline reflects what the company has been
promoting for a number of years - the efficient
and environmentally responsible storage and
dispensing of fuel oils.
Balmoral has developed a range of products for
storing and dispensing fuel oil, diesel and
heating oil while also introducing a
comprehensive range of waste oil tanks.
Ranging from 1135-10,000 litres, the
company’s bunded tanks and “Superfill”
dispensing stations are the result of substantial
R&D investment.
Supported by a nationwide group of distributors,
Balmoral operates a highly efficient transport
network that guarantees deliveries in
accordance with client requirements.
Allan Joyce, managing director of Balmoral

for the noise made by water leaking from pipes
and, when a potential leak is detected, they enter
an alarm state and transmit a radio signal to
indicate a "LEAK" condition.
Loggers can be quickly deployed and used
repeatedly with no disruption to the surrounding
area or to the water supply, and the precise
location of each logger can be recorded onto
detailed GPS mapping software as it is put into
the ground. Each is immersion-tested to IP68,
enabling continuous operation even in flooded
chambers. They are powered by low cost,
replaceable batteries and are tough enough to
ensure that long-term low leakage levels can be
achieved and held easily, with minimum
maintenance.
PermaNet can be configured to send an
automatic alert whenever one of the loggers
reports a potential leak, meaning leakage teams’
speed of response and accuracy of deployment
can be maximised. This increased efficiency
means that both new and existing leaks can be
targeted more quickly; saving more water, and
reducing the risk to surrounding infrastructure. A
complete network of devices creates a powerful
system to supply up-to-date flow data and
effective water management. Leak sizes can be
determined by matching daily leak alarms with
flow data, and problem zones can be brought
quickly and effectively under control.
A new development called ALMOS (Acoustic
Leak Monitoring Online System) now uses this
data, in conjunction with popular online
mapping technology, to provide a live, on-screen
tracking application for deployed Permalog
loggers from any internet-connected PC, without
any specialist software. The location and leak
status of each logger is displayed directly and
accurately on a map of the area, with further
information available at the click of a button.
Fuel oil storage in Scotland deadline looms
Tanks, said: “As an independent and clientfocused
company, we continue to invest in our
range of products ensuring that every
requirement is met. Having pioneered the
industry with bunded tanks and customised
dispensing stations we believe we are uniquely
placed in the UK sector.
“We understand market demands and make it
as easy as possible for clients to order precisely
what they need and have it delivered when and
where they want it. This is
no small consideration
when you think about the
size of some of our larger
tanks.
“So, whether you require
a 500 litre waste oil tank
or a 10,000 litre fully
equipped Superfill we
would welcome the
opportunity to discuss
your specific
requirements.”
Offering a distinctive
service to the industry,
Balmoral Tanks has
developed a number of
web-based training
modules - one of which
focuses on fuel oil
storage. The fuel oil storage training module
covers essential information and is split into three
easy to understand sections: product, process
and market; product selection and accessories;
installation, maintenance and legislation.
“We are optimistic that customers will see the
value of this online information”, said Mr Joyce.
“Clients and users can develop their knowledge
at a time that suits them and their business
needs.”
