Wastewater treatment

Sewage is sewage discharged into the daily lives of residents, mainly from residential buildings and public buildings such as homes, institutions, schools, hospitals, shops, public spaces and industrial toilets.

The pollutants contained in domestic wastewater are mainly organic substances and a large number of pathogenic microbial parasites, eggs and intestinal infectious diseases. The organic substances present in domestic wastewater are extremely unstable and easily deteriorate and cause an unpleasant odor. Bacteria and pathogens multiply by organic matter as nutrients in domestic wastewater, which can lead to the spread of infectious diseases. Therefore, domestic wastewater must be treated before discharge.

To treat domestic wastewater, it is necessary to build a pipeline system, and pipelines, naturally, cannot be separated from valves. Valida Valve provides you with a complete set of solutions for household wastewater treatment.
