The small size, light weight, simple operation, power consumption province, large capacity, high dehydration efficiency and facilitate the whole process of automatic or semi-automatic network control and other sewage treatment facilities. Belt filter press. Environmental Protection Equipment Co., Ltd. Shandong Ruizhao Xiang belt filter press works: Sewage sludge through sludge and a concentration of flocculant concentrate mixed in static and dynamic mixer after the sludge in the tiny solid particles polybrene into larger flocculent mass, free water while separating belt filter press sludge Supplying, flocculation sludge is transported to the concentrate after gravity belt filter dewatering, free water is separated by gravity formed non-flowing state of sludge, then sandwiched between two upper and lower belt belt filter press sludge process, through the wedge pre-nip area of ??low pressure and high pressure zone steeled pressing force, shear force belt filter press sludge drawings, gradually squeezing the sludge, in order to achieve the greatest degree of mud, water separation, and finally form a filter cake discharge.
