Analysis of Secondary Pollution in Drinking Water Ultrafiltration System

Abstract:

Ultrafiltration processes are increasingly popular in drinking water treatment, as it can provide better quality water by removing microorganism and turbidity with lower filtration pore size, even without disinfection. Nonetheless, in our experiment the bacteria was occasionally detected in ultrafiltration effluent, and the related literature once had also been reported. This study was focused on the cause of secondary pollution in the drinking water ultrafiltration system, mainly from the production tank, biological stability, bacteria in air, as well as the membrane structure. And some solutions, including production water tank chlorination periodically, changing the operating mode of the ultrafiltration system, improving the design of the production tank, were studied to control secondary pollution in the treatment system.
