sludge dehydrator

Wastewater by treating precipitation can lead to large sludge , after concentrating and digesting process ,moisture content is still as high as 96% ,volume is very big ,difficult to xiaoNa disposal ,must pass a dewatering processing , increasing the containing solid rate of mud cake , to reduce the area of sludge piled up .

sludge dehydrator classification

General large and medium-sized sewage treatment plant adopt mechanical dehydration .

There are many kinds of dehydrations , according to the dehydration principle can be divided into the vacuum filtration dewatering , pressure filtration dehydration and centrifugal dehydration three categorized .

1,Belt filter press sludge dehydrator

Belt filter press hydroextractor is by two zhang tight filters , from a series regular arrangement in an-shaped shape in the roller .Rely on filters itselt to the formation of sludge layer tension squeeze and shear forces , the sludge layer of capillary water containing solid extruded , obtain the high mud cake , so as to achieve the sludge dewatering .
