From Solid–Liquid Separation to Efficient Fertilizer Production

If you want to achieve higher profits from solid–liquid waste separation, the best strategy is to turn both the liquid fraction and the solid residue into valuable fertilizers. A solid-liquid separator is not only a waste-handling machine—it is the first step of a complete fertilizer production process.

  Turn Liquid Effluent Into Liquid Organic Fertilizer

  Separated liquid is an ideal raw material for liquid organic fertilizer. After dewatering, you only need a few key machines to complete the production process: a duplex filter for impurity removal, a UV sterilizer for safety, an anaerobic fermentation tank, an ingredients-adding tank, and an automatic filling machine. With this equipment setup, you can easily convert manure wastewater into high-value liquid fertilizer.

  Turn Solid Residue Into Solid or Granular Fertilizer

  The separated solid residue is also a profitable resource. You can compost it and produce powdered or granular organic fertilizer for market sale. This process typically requires compost turners, shredders, drum screening machines, a packaging scale, and optional granulation equipment such as a disc pelletizer or double roller granulator. A rotary coating machine can further improve product appearance and shelf stability.
