flotation technology

proaqua - flotation unit SF4
The SF4 flotation unit is proaqua's standard equipment for use in
flotation processes, needed to separate sludge from water in industrial
applications.
The cost-effective proaqua SF4 is available in three standard sizes to
perform common applications such as:
● sludge extraction in paint processes
● sludge extraction in waste water processing
Other applications for the SF4 flotation unit can be found in
● the chemical, food and pharmaceutical industries
● cleansing plants
Our experts dimension the flotation units to your production site after a
thorough analysis which assesses and includes all relevant
parameters.
The proaqua SF4 is supplied as a "ready-to-use" module for water
currents up to 20 m³/h.
Larger units up to 50 m³/h will be installed and put into operation on
site by highly qualified proaqua personnel world-wide

Standard units
The proaqua SF4 is available in three standard sizes.
All dimensions are based on proaqua's extensive experience in the field
of waste water processing.
All three models, the proaqua SF4k, SF4m and SF4v, use a dn80 /
dn100 gravity drain for clean water return.
The equally sized models proaqua SF4kP, SF4mP and SF4vP are
equipped with an integrated clean water buffer tank and a level
controlled pump to transport the cleaned water to any desired location.
These options enable the proaqua flotation units to operate even in
difficult and space-constrained environments.
Customised dimensions, customised equipment
All proaqua equipment is engineered and manufactured at proaqua's
own workshop at the company's headquarters in Mainz. This enables
proaqua to build all flotation technology equipment according to your
specifications and needs and to make equipment and units with nonstandard
dimensions available anytime.
proaqua will integrate your process control systems or functional
connections to peripheral equipment such as dosing pumps according
to your needs.
Several properties of the SF4 flotation unit depend on the particular
use and will be specified in co-operation with you based on proaqua's
process analysis.
Our specialists are ready to advise you anytime!

proaqua - flotation units : accessories
Surface suction device proaqua SAS
The proaqua SAS optimises the collection of floating sludge.
The proaqua SAS includes a unique float construction which eliminates
the need for adjustments of the suction pipe towards the water surface.
It can compensate variations in water level up to 150 mm and all
changes of water current to the flotation unit SF4.
The proaqua SAS is typically used with the proaqua SF4 flotation units.
Min. water level 150 mm, max. water level 300 mm.
Footprint 300 x 300 mm.
Other dimensions available as required!

Sludge container SAK-300
Dispose of solids instead of water!
The proaqua SAK-300 collects and drains the sludge produced by a
proaqua SF4 flotation unit.
The perforated metal element placed inside the container allows water
to quickly drain from the sludge.
To transport the drained sludge, the SAK-300 can be moved around on
its wheels or by fork-lift.
The container can be emptied without much effort from the fork-lift's
driver seat by operating the SAK's dumper mechanism.
Fitting filter bags made of PP fleece are available from proaqua.
Volume approx. 300 litre (also available in 500 litre)
welded oil- and watertight exterior, including one 1“ drain valve,
perforated sheet metal element on 4 sides, clearance to wall 20 mm,
8 mm holes, division 20 mm, front side without perforated sheet metal.
Mobile on 4 wheels (2 steerable wheels, 2 wheels with brake).
