Dewatering presses are one of several solids / liquids separation technologies used to treat municipal and industrial sludges and other waste materials. By reducing the volume of the solid material, disposal costs can be greatly reduced. Read More

With belt filter presses , a chemically treated sludge is sandwiched between two belts that pass through a series of rollers, effectively squeezing the water out. The final cake will typically be up to 35% solid.

In a plate and frame filter press the sludge is pumped into a framework of vertically orientated plates. As the chamber fills the pressure increases. The filtrate drains away and the dewatered solids build up in the spaces between the plates.

Membrane filter presses work in a similar manner, except that towards the end of the process the plates are inflated to to further compress the filter cake. This results in a drier end product.

Screw presses can operate on a continuous basis. Sludge is fed into the device and dewatered at the inlet point by gravity drainage. As the sludge is moved by the screw to the discharge point it is compressed and more water is forced out.

Alternative dewatering technologies include centrifuges and sludge thickeners
