Dehydration process

       Doyen China has a scientific belt press dehydration process. The dehydration principle and dewatering flow sheet are as follows.

       After mixing with the prepared flocculation in the dynamic and static mixer, the small particles solids in the concentrated sludge would form bigger size of flocculated sludge and the free water is separated. Flocculated sludge is conveyed to the belt then it further goes to the gravity dewatering area. Under the gravity,free water would fall on the tray, and the rest sludge would be nipped between two belts. Then it would further goes to the wedge zone for pre-filtration, and the to low pressure zone and high pressure zone through the decreasing diameter rolls. Under the extrusion and shearing force, the solid and liquid is separated. Finally filter cake with expected low moisture content is discharged.

       For different industrial sludges, different type of flocculants is required. Normally the feeding consumption is about 0.05%–0.1%. According to different throughput, the roller quantity, extrusion allocation, belt tension, structure and speed is also different in order to achieve an efficient and satisfied dewatering effect. Therefore, we would make unique design to meet the requirement of every customer.

      Doyen specializes in providing belt press equipment for the Southeast Asian market. Welcome to visit our workshop, according to the actual situation of your company, develop a more scientific dehydration program.Welcome to joyce@doyenchina.com or visit https://www.doyenchina.com.
