Comparison of RO Membrane Performance: From Qualification Testing to Full Scale Application at West Basin MWD

This paper presents the results of various RO membranes that have been tested at West Basin in 5,000 hour qualifications trials. The fouling nature of the sourcewater results in a marked difference In performance of diffent RO membranes. The protocol that was used to identify the membranes that would perform better on this water source is presented.
