Abstract
A variety of coagulants were investigated for potential as a microfiltration pretreatment to improve NOM removal from drinking water. The impact of pretreatment upon subsequent membrane performance was investigated in both laboratory and pilot-scale trials. Membrane flux decline rates were reduced by pretreatment, but improvements were similar for all coagulants tested, including alum and prepolymerised aluminium and iron-based coagulants. These findings suggest that physical property differences between the floes of different coagulants do not significantly impact membrane performance when formed and removed under typical microfiltration plant operating conditions.
