Filter Presses for dewatering As sludge treatment
specialist, we have developed various concepts for different
sludge dewatering applications. DEWA offers a full range of
dewatering equipment that provides superior performance, mechanical
reliability, long-life durability and user friendly features.
DEWA belt filter press design is one of the most efficient
sludge dewatering units which can be applied through organic
and inorganic sludge’s to achieve required results at
minimum operating cost.
Sludge dewatering systems generally include a pre-dewatering
section (BTN) for thin sludge suspensions. It not only reduces
the sludge volume, but also increases enormously the capacity
of subsequent dewatering units.
The DEWA belt filter press can handle very thick sludge’s
and for this an independent gravity drainage deck is provided
to pre-thicken the sludge before it enters the main wedge
and pressing sections.
Basically in the BFP, the sludge dewatering is achieved by
bringing the sludge between the two moving belts which in
turn moves on the varying sizes of rollers keeping belts under
tension through pneumatic (or hydraulic) cylinder system which
results in squeezing out the liquid trapped between the solids
and withdrawn separately through the filtrate trays. An adequate
arrangement is provided for auto belt tracking / tensioning
which makes the system operator friendly.
DEWA Belt Presses have been used
in all five continents with great success in a wide variety
of applications - from industrial and municipal water &
waste water treatment to food processing, slaughter house
applications and refineries.
