Abstract

Combining the ceramic membrane microfiltration with alkaline agent,a new method is proposed to treat deep well water(Ca2+ 250一400 mg/L) from Pengshan district in Sichuan. It is observed that the flux change arises from pressure and temperature difference. The cleaning of membrane fouling by ultrasonic is tested. The results show that alkaline agent(Na2C03) is effective to decrease the degree of hardness of deep well water. Appropriate temperature and higher pressure difference are benefit to increase the flux. It is effective to clean membrane fouling by ultrasonic.
