The remaining sludge from the sludge pit (primary sediment, secondary sediment) going though the shear pump which smash the glass, plastic bags. The feeding pump feed the sludge (concentration 0.5 ~ 4%, or higher) into the centrifuge, at the same time, dosing pump is automatically dosing flocculant (concentration 1 ~ 3 ‰) into the pipeline. Therefore, the sludge turned to be pellet floc before enter the centrifuge. After the separation of the centrifuge, the dewatered mudcake is discharged from the drum and discharged to the outside through a screw conveyor. The dewatering system is widely used in municipal wastewater treatment such as oxidation ditch, AB, A / O, A2 / O, SBR and MBR processes as well as traditional sewage treatment processes.
1. Water content in dewatered solids: 65%-81%
2. Solids content in liquid after separation: lower than 0.05~0.2%
3. Solids recycle rate: no less than 85%~98%
4. Chemical consumption per ton dry solids: 1~5kg/TDS
