Full Description

Pilot-scale evaluations of individual membrane modules have been performed according to two tiers, short-term and long-term testing. The focus has been on low-turbidity surface waters which potentially require minimal pretreatment, with the primary objective of DBP precursor removal. An emphasis has been placed on nanofilters (NF), with microfilters (MF) and ultrafilters (UF) considered as potential pretreatment steps before NF. The Tier I work was intended to define short-term precursor rejection efficiencies while Tier II work was intended to elucidate potential fouling behavior over longer time frames (30 days).
