Cost Effective Screw Sludge Dewatering Machine Wastewater Treatment Municipal Industry
Cost-Effective Wastewater Treatment Municipal Industry Screw Press Sludge Dewatering Machine
Mechanical sludge dewatering serves for further reduction of sludge volume and mass by removal of sludge water from interstices between sludge particles. A more or less firm sludge cake is produced.
Prior to its dewatering, fed sludge is first flocculated by addition of polymers. The choice of polymer and its dosage as well as rapid and intensive mixing are decisive for optimal floc formation and dewatering results.
Working Principle
1 The conditioned sludge flows into the filter chamber from the flocculation tank and is pushed forward the discharging end .
2. With the gap between the thread of the shaft is getting higher and higher.
3. Then the water is separated from the sludge and flows out from the gap between the movings and the fixed rings.
4. The movement of the moving rings the fixed rings cleans the gap between them and prevent the machine from blockage.
5. The filtered sludge cakes are pushed forward by the shaft and finally discharged from the end.
