The design of the Airlift MBR Megablock
contains several unique characteristics
that lower the energy consumption and
thereby lower the total costs of operation.
The Airlift MBR Megablock offers flexible
operation as it can handle fluctuating
fluxes, which is ideal for WWTPs as
they are constantly struggling with
fluctuating fluxes due to daily cycles and/
or weather conditions as unpredictable
circumstances.
Unlike other MBR systems, the Airlift
MBR Megablock is able to switch off
units that are not needed. This lowers the
energy consumption by 25 to 50 percent
when compared to submerged systems
that need regular aeration to prevent the
sludge from settling to the bottom of the
tank if the aeration is switched off. The
SED (specific energy demand in kWh/m³)
of the Airlift MBR Megablock thus offers
significant cost savings during low flows,
which is a major step forward in the water
reuse market.
Within the Airlift MBR Megablock concept,
the Compact 32V membrane modules are
not placed in a traditional skid, but into an
innovative frame construction with a small
physical footprint. The smart and robust
plug-and-play system can be constructed
quickly and easily onsite.
Modular pre-fabricated segments provide
simple and reliable mounting and easy
connection on the plant. The simplified
connections result in a faster total
construction time and significantly reduce
the time required for unit built-up and
membrane loading.
Each Megablock consists of 36
ultrafiltration (UF) membrane modules with
a nominal capacity of 75 m3 /h. The simple
expandable style design makes it possible
to easily extend the system to a maximum
of six sections for a total of 216 membrane
modules when extra capacity is required.
A full Megablock with six segments is 18 m
(59 feet) long and delivers up to 10 MLD
(2.64 MGD) crystal-clear, bacteria-free
water.
The Compact 32V modules are placed
outside the bioreactor and all modules
can be reached individually. Due to the
externally mounted membrane system,
the wastewater is on the inside rather than
the outside of the tubular membranes
providing a cleaner working environment
for treatment plant staff. The operator is not
in direct physical contact with the sludge,
can work within controlled air conditions
and does not have to work inside the sludge
tanks.
Moreover, the cleaning of the membranes
is entirely automatic without operator
intervention and even hair and lint are
removed automatically by the DrainStep
system. The Airlift MBR Megablock also
offers a unique integrity detecting solution.
In case of an incident, the integrity of the
modules can be checked individually without
dissembling the whole unit.
