◆ Process: raw water; grille; regulating tank; lifting pump; bioreactor; circulating pump; membrane assembly; disinfection unit; reclaimed water storage tank; reclaimed water system

◆ Sewage enters the regulating tank through the grille and enters the bioreactor through the lifting pump, the aerator is oxygenated by the PLC controller, the effluent of the bioreactor enters the membrane separation treatment unit through the circulating pump, the concentrated water returns to the regulating tank, the membrane separated water is chlorinated and sterilized by rapid mixing method (sodium hypochlorite, bleach powder, chlorine tablets) and enters the middle water storage tank. The backwash pump uses the treatment water in the cleaning tank to backwash the membrane treatment equipment, and the backwash sewage returns to the regulating tank. the lifting pump opening and closing is controlled by the water level in the bioreactor. The filtration operation and backwash operation of the membrane unit can be controlled automatically or manually. When the membrane unit needs chemical cleaning operation, close the inlet valve and sewage circulation valve, open the medicine washing valve and the medicine circulating valve, start the medicine liquid circulating pump, and carry out the chemical cleaning operation.
