The kitchen drainage contains fish oil,
Although a considerable amount of oil such as tempura oil is contained, all conventional kitchen wastewater treatment systems only separate solids and liquids into solids and liquids. Since it remains in the solid-liquid separation tank while floating, it rots in the tank and causes odor, or adheres and solidifies on the inner wall of the tank and the inner wall of the pipe, so that the frequency of maintenance for removing this is increased. Alternatively, there is a problem that deposits accumulate over time and hinder stable operation or are discharged together with the treated water to cause environmental pollution.
