Due to the floating design and the
consistent overflow height of the sip and suction unit, the setting
of the desired effluent volume on the one hand and the setting of
the desired mixture ratio of scum to water to air can be adjusted
in a wide range. Floatables of all consistencies and thickness are
effectively and quickly removed by the submersible pump.
With suction scrapers and effluent
In combination with submerged scrapers
with a central drive unit and circular
submerged effluent pipes.
In rectangular tanks with chain and flight scrapers.
The weight balanced HDPE swivel arm mountings of the floating screw
conveyor elements allow and ensure the maintenance free and consistent
function of the sip and suction unit even at water level fluctuations
up to 500 mm, e.g. due to variations of flow rate or the effect
The possibilities of this System are unlimited. The modular design
and the standardised mounting elements allow the simple and flexible
installation in any kind of sedimentation tank, on any kind of scraper
bridge and in combination with any kind of outlet. The system is
ideally suited for refitting existing scrapers and tanks, as it
automatically compensates any existing constructional inaccuracies
by the floating design.
... for self-controlled and self-regulating operation
Precise self-adjustment to fluctuating water levels in combination
with the sludge pump allows a fully self-regulating operation with
efficient and self controlled pumping of the desired concentration
of sludge / water / air.
In addition to the continuous operation for large volumes of floatables
or for the incident of a process upset, the system can also operate
fully self regulating at regular intervals. Using the system with
temporally delayed activation of the submersible pump in comparison
to the rotation of the screw conveyor elements even enables to pre-concentrate
For the paper industry, with an overhead sludge
With a tubular bridge construction and
radial submerged effluent pipes.
... for minimum maintenance
All used materials are selected with respect to exceptional durability
and minimum maintenance. Stainless steel is used for all components,
HDPE for the maintenance-free bearings, HDPE and POM for the maintenance
free drive chain and drive sprockets, water and weather proof elastomers
for the seals. Industry standard materials are only used for the
submersible pump and the drive motor.
Due to the system's floating design, the bearings are not under
load and the maintenance consists of periodic visual inspections
and the sludge pump's annual oil change. Therefore the pump can
be raised without loosening any parts by the use of lifting booms,
rail guides and special elastomer seals at the suction and pressure
