Washing sewage treatment

Why do algae grow wild? The main culprit is that the nitrogen, phosphorus and potassium in the water exceed the standard seriously. A large part of phosphorus comes from the washing wastewater discharged into rivers and lakes. According to incomplete statistics, about 500-600,000 tons of sodium tripolyphosphate washing wastewater is discharged every year in China, which has greatly exceeded the degradation capacity of the water itself. Washing wastewater is strictly prohibited from being discharged directly in all parts of the country, and can be discharged only after the treatment and the effluent quality reaches the standard.

Washing wastewater mainly contains surfactant, sodium tripolyphosphate, cellulose, oil pollution, dust-sealed particles, various microorganisms, etc., with high PH value and high suspended matter content. For the treatment of washing wastewater, NanoMem® has developed integrated washing wastewater treatment equipment with flat ceramic membrane as the core technology. The combined process of flocculation sedimentation and flat ceramic membrane is adopted to effectively remove bacteria, viruses, microorganisms, nitrogen, phosphorus and other pollutants from washing wastewater. The effluent quality reaches the first-class national discharge standard.
