Types of Sludge dewatering machine
Sep 07, 2018

Sewage treatment Plant Sludge has: physical and chemical sludge, biochemical sludge, chemical and biochemical mixed sludge, such as three kinds. A variety of sludge to the dewatering machine adaptation has a certain difference, the current domestic sludge dewatering machine commonly used models are: centrifugal, filter belt type, spiral ring dispatch type and plate frame type. Precipitation sludge dehydration, the selection of flocculant and the proportion of the operation is very important, flocculation effect is good, sludge dehydration relatively smooth.

The following is a brief introduction to the actual use of three models for selection: Centrifugal type: Three kinds of sludge can adapt, but high energy consumption, high speed caused by noise. Filter Belt Type: Adapt to the physical and chemical sludge, and cake water content is low, the mixed sludge and biochemical sludge adaptability is poor, reflux sludge, backwash water consumption, high energy consumption, maintenance complex.

Spiral Ring Dispatch Type: The first generation dehydration machine represented by the Japanese prototype has been popularized and applied for 3-4 years, the disadvantage is the low yield.
