Spiral solid-liquid separator

Solid-liquid separators are used for separating liquid from animal manure, high-concentration organic wastewater from livestock farms, such as chicken, cattle, and horses, and various other intensive animal husbandry operations. A solid-liquid separator is a machine used to separate solid particles and flocculent matter from liquids, primarily utilizing centrifugal force.

With the development of livestock farming, the government's environmental protection requirements are becoming increasingly stringent. Efforts are underway to address environmental pollution from farm wastewater and manure. Manure solid-liquid separators are also undergoing continuous innovation and technological advancements to address a wider range of livestock manure issues. Therefore, these separators can be used to treat a wide range of livestock, poultry, and animal manure. They offer high efficiency, high-end patents, and competitive pricing, ensuring better service to the public.

Solid-Liquid Separator Effects

1) For livestock farmers whose existing biogas digesters are too small and whose wastewater retention time is too short, resulting in high wastewater concentrations, a livestock manure solid-liquid separator can be used to treat the wastewater before it enters the digester. This effectively reduces the COD and BOD contents of the wastewater, alleviating the operational load on the digester and streamlining wastewater discharge.

2) Using a solid-liquid separator can transform feces in fresh sewage into valuable fish feed or organic fertilizer. The separated sewage is intermittently fed into the biogas digester, allowing the anaerobic digester time to fully digest the wastewater. This allows the active bacteria in the digester to thrive, resulting in higher gas production. This naturally increases the methane content and purity of the gas, thus overcoming issues with biogas generator malfunction.

3) Sewage treated by the solid-liquid separator is fed into the digester, effectively preventing biogas digestion and eliminating the need for cleaning the digestate.

4) Using a livestock and poultry manure solid-liquid separator can reduce the investment in biogas digester construction. For example, if a farm discharging 100 tons of wastewater daily uses a matching livestock and poultry manure solid-liquid separator for pre-treatment, the investment in anaerobic digesters can be reduced by 300 cubic meters. Because the concentration of manure and sewage mixed into the digester is too high, the anaerobic digester needs to be extended accordingly. Therefore, if a farm discharging 100 tons of wastewater daily does not use a livestock and poultry manure solid-liquid separator, the investment in anaerobic digesters would be 1,000-1,200 cubic meters. Using a livestock and poultry manure solid-liquid separator can reduce the construction cost by 300-400 cubic meters.
