Many utilities are considering low-pressure membranes (microfiltration/ultrafiltration) as an advanced treatment option to meet future regulations and to protect public health. There are many possible process configurations and each has performance, operational, and cost implications. The purpose of this paper is to present a strategy for evaluating membrane process configurations and systems. This strategy involves designing pilot-scale studies, evaluating the results, and formulating design criteria. The implementation of this membrane selection strategy is demonstrated for a utility in the Metropolitan Salt Lake City area, which is planning a new 70 mgd water treatment plant. Two treatment trains involving membranes were evaluated. A membrane selection framework in which membrane systems were examined and screened is described. A pilot-scale study was conducted to determine the performance of the three membrane systems selected, in each train. The design of the pilot-scale tests is presented and results from these evaluations are discussed and interpreted. Includes reference, table, figures.
