The primary objective of this project was to evaluate polyvinylidene difluoride (PVDF) membrane modules for performance treating ozonated secondary effluent water. West Basin Municipal Water District constructed its own custom engineered membrane filtration (CEMF) pilot system that is capable of independently operating up to three different pressurized membrane filtration modules in parallel. Pilot testing for seven PVDF modules was conducted over the course of 18 months. Five of these modules were considered qualified for use at the West Basin Municipal Water District facility, and the results of this pilot test were used to develop design conditions for each of the qualified modules for a future full-scale CEMF system. The research results can be applied by other facilities that also have a challenging feedwater or an ozonated secondary effluent feedwater. Published in 2022.
