  • To study the pollution control of microfiltration, PVDF hollow fiber microfiltration membranes were used to treat dyeing wastewater. It was important to optimize the membrane flux in order to control the membrane fouling. Membrane flux of 31 L/(m2·h) was reasonable when treating wastewater. Sodium hypochlorite and sodium hydroxide was found to be effective in the chemical cleaning. Forwardwash demanded less agents compared to backwash. It only cost 0.06 yuan of sodium hydroxide producing every ton of water. Forwardwash using raw water after chemical cleaning enhanced the recovery of membrane.

Abstract: To study the pollution control of microfiltration, PVDF hollow fiber microfiltration membranes were used to treat dyeing wastewater. It was important to optimize the membrane flux in order to control the membrane fouling. Membrane flux of 31 L/(m2·h) was reasonable when treating wastewater. Sodium hypochlorite and sodium hydroxide was found to be effective in the chemical cleaning. Forwardwash demanded less agents compared to backwash. It only cost 0.06 yuan of sodium hydroxide producing every ton of water. Forwardwash using raw water after chemical cleaning enhanced the recovery of membrane.
