Analysis of Nanofilter Fouling in Potable Water Treatment


The province of Manitoba has many lime/soda water treatment plants unable to meet the latest provincial quality standards for chlorine disinfection by-products – trihalomethanes (THMs). As a result, many municipalities are looking for other alternatives. One suitable alternative is a dual membrane plant using ultrafiltration and nanofiltration (NF). Typical surface water sources in Manitoba contain major membrane foulants in relatively high concentrations, specifically DOC and hardness. Control of membrane fouling allows for longer filtration runs and for less water to be rejected, which is directly related to the operating cost of the plant. Membrane fouling is influenced by the quality of local water, and the effect of the water of the Canadian Prairies on membrane filtration is not well understood. We propose to study the mechanism for NF membrane fouling in a Manitoba plant, and gain knowledge that will enable its control.
