Treatment of municipal and industrial wastewater

Wastewater treated by the Rugao Hengfa Facility comprises both municipal and industrial wastewater discharged from Rugao ETDZ. To deal with the added industrial effluent, chemical agents are introduced early in the process to facilitate the precipitation of industrial compounds. The process generally consists of four stages whereby wastewater is pre-treated with chemicals, before being subjected to biological reactions, chemical reactions and disinfection.
