The microfiltration drum solid-liquid separator is a national agricultural machinery subsidy product, designed for low-concentration, low-solids materials to solve the low efficiency problem of traditional separators. Sewage is pumped into the machine, initially filtered by the microfiltration drum, with liquid discharged directly and solids sent to a screw press for secondary dewatering. Dry materials can be bagged directly, and the effluent has very low solids content, making it an efficient equipment for large-scale breeding and environmental treatment.
