Belt Press

 

A belt press is ideal for dewatering sludge produced from industrial wastewater treatment plants such as DAF systems, Clarifiers plus Activated Sludge and Sedimentation processes. A volume reduction of up to 97% can be achieved.

EWT manufacture a comprehensive range of belt presses from 0.5m, 5 roller economy units to 3m wide, 9 compression roller machines with the largest systems handling up to 800Kg/hr dry solids.

 

All EWT belt presses are manufactured in stainless steel as a standard. All belt presses are of heavy duty construction, for treating 500 L/h through to 80 m3/h of sludge.


 

 

 

EWT's Belt Presses can be fitted with pre-thickening in order to process sludge when the initial concentration is less than 1.0% w/w solids. The pre-thickener can be either a gravity belt thickener or rotary screen thickener. The use of a Gravity Belt Thickener can enable the dewatering of up to 120 m3/h of sludge in single train.

EWT can offer packaged dewatering systems including ancillaries such as controls, pumps and Automated Polymer Rigs. Skid mounted and trailer mounted units are also available.
