Sludge dewatering

Sludge activated treatment: belt press

Introduction to sludge dewatering

Dewatering processes provide a concentrated, consolidated product − retaining most of the solids from the original sludge – along with a diluted stream which is predominantly water.

Dewatering processes apply a significant mechanical force to achieve increased water removal over that possible from thickening.

Benenv Screw press for sludge dewatering

Film to demonstrate the stacked screw sludge dewatering machine from Benenv.

This solid-liquid separation equipment can be used for applications including municipal sewage, petrochemical, food & beverage, slaughterhouses and breeding, printing and dyeing, papermaking, leather, pharmaceutical and other industries.

The equipment is suitable for high and low concentration sludge (from 2000mg/L), and for all kinds of sludge with high and low viscosity, especially oily sludge.

Phosphorus recovery by sludge acidification and dewatering

A pilot-scale Danish study of phosphorus extraction from acidified anaerobic and aerobic sludge samples has revealed removal to be more effective from anaerobic sludges, even though the digested sludge alkalinity increases the total acid demand.
