The role and specific way of sludge thickening and dewatering Jan 23, 2019

Sludge thickening and dewatering is based on the principle of sludge concentration. The thickened sludge still retains the characteristics of the fluid, and the concentrated sludge is dewatered by natural drying or mechanical dewatering. The so-called sludge thickening refers to reducing the water content of the sludge and reducing the volume of the sludge by thickening the sludge, and the thickened sludge is further subjected to dehydration treatment.

 

Sludge thickening and dewatering is a combination of two parts. It is an advanced dehydration process developed by digesting and absorbing foreign advanced technology. As a supporting technology for sewage treatment, it can suspend suspended solids and sediment after air flotation. Depressurization by pressure filtration and pressing into a mud cake to prevent secondary pollution.

 

The thickening and dewatering of the sludge is thickened in the sedimentation tank or sedimentation tank. The water removed from the thickening needs to be treated, and it can be returned to the inlet of the off-site wastewater treatment plant or recovered from the field equipment by an aerobic treatment process. sludge. The purpose of dewatering is to further reduce the water content, which can be mechanically dewatered using a filter press or a centrifuge.
