A Belt Filter Press is a Biosolids/sludge dewatering device that applies mechanical pressure to a chemically conditioned slurry, which is sandwiched between two (2) tensioned belts, by passing those belts through a serpentine of decreasing diameter rolls.
The unique technologies built into each PEWE DeWater DBP belt filter press are designed to maximize solids recovery while minimizing chemistry usage during sludge dewatering. Selection of the appropriate belt press system depends upon the sludge solids characteristics encountered.

Belt Press Dewatering System Sludge dewatering unit which can be applied through organic and inorganic sludges to achieve required results at least operating cost. The Belt Press can handle very lean sludges and for this an independent gravity drainage deck is provided to pre-thicken the sludge before it enters the main sections.

Belt filter press dewatering is a solid/ liquid separation device, applied for the dewatering of sludge in the pulp and paper mill, chemical industry, printing and dyeing mill, mining and sewage treatment. The process of dewatering is achieved by passing a pair of filtering cloths and belt through a system of rollers, the system takes sludge or ...
The flushing unit, sludge feeder and distributor and the filter cake removal device are provided with the filter press. In the “Comby” version, the thickener is installed onto the frame of the filter press: thickened sludge removal is carried out onto the filter press belt for further dewatering. Belt Thickener …

Aerobic Digested – Cake Solids of up to 24% TS. ATAD Process – Cake Solids 30% @ 2000 Lbs/Hr/meter. Lagoon Sludge – Solids loadings of 2500 Lbs/Hr/meter producing 20% Solids.
Belt Filter Presses are intended for the mechanical dewatering of wastewater sludge, as well as of the water conditioning sludge, and of the industrial slimes. Belt filter presses are used extensively at the wastewater treatment plants due to its high productivity and reliability. For sludge with an initial moisture of more than 97.5%, the capacity can be increased by the use of “Comby ...
When the sludge is dehydrated by a belt filter press, decanter or filter press, it might be necessary to use lime and convey it to storage (bin, area, silo, etc.). Sodimate, in addition to its quicklime discharge and metering installations and the twin-shaft mixer MBV, designs sludge handling and conveying systems by shaftless screw conveyors ...
The pre liming sludge stabilization is usually used for 2 types of application. 1 / Sludge dewatering by filter press. A lime milk made of hydrated lime (lime milk preparation tank) or quick lime (lime slaking unit) is injected into the conditioning tank allowing increased dewatering performances. 2 / Sludge dewatering by centrifuge.
Belt filter presses are industrial machines, used for solid/liquid separation processes, particularly the dewatering of sludge's in the chemical, mining, and water treatment industries. A costly burden on many companies, belt filter presses require continuous staffing and excessive maintenance costs that often surpass the expenses needed to ...
Product desprication 1) On the basis of TLYL belt filter press,we absorbed the latest mechanical concentration and dewatering method in foreign countries and developed the new integrative concentrated, press filter and dewatering machine for sludge. 2) Sludge fully reacts with coagulant will flow into material distributor in concentration part then dewatered along the movement of filter cloth ...
Belt Filter Press DESCRIPTION Belt filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as “cake”. Dewatered residuals, or cake, vary in consistency from that of custard to moist soil. Dewatering serves the following purposes: C Reducing the volume, thus reducing storage
Typically, a belt filter press receives a slurry ranging from 1-4% feed solids and produces a final product of 12-35% cake solids. Performance depends on the nature of the solids being processed and dewatering biosolids and industrial sludges serves many purposes:
