Liquid Manure Dewatering

The manure produced in animal farms is of high value as a liquid fertilizer for plant growth. However, for a large farm or breeding farm, how to effectively manage the large amount of manure produced every day is difficult. If the liquid manure are not effectively treated, the nitrogen, ammonium, and phosphorus contained in the liquid feces will not only affect the environment, but also have certain hazards to human health. The ZK separation technology solution will effectively solve this problem.

ZK SEPARATION Decanters Application in Liquid Manure Dewatering Industry

ZK separation animal waste centrifuge is a decanter centrifuge specially designed for separating and processing animal liquid manure. Excellent performance in manure and fertilizer management can ensure that animal farms to meet environmental protection standards, so that the discharged water quality and phosphorus meet regulatory requirements. The ZK centrifuge is used in the centrifugal dewatering of liquid fertilizers, which can effectively separate liquid manure into solids and irrigation water. The separated solid is odorless and storage is very simple. After subsequent processing, it can be sold as natural fertilizer. The separated water can be used for plant irrigation. The application of ZK decanter in the treatment of liquid manure can effectively reduce the operating costs of aquaculture enterprises.
