The required quality of drinking water has increased steadily in the past three decades in response to health-effects studies, public concerns and advances in analytical techniques. Membrane systems are suited to meet new regulatory demands via integration into existing systems or as stand alone treatment systems. Utilities are in need of operational and water quality information for integrated membrane systems (IMSs) cost and performance. Information on IMS surface water treatment is especially limited because few full-scale systems exist and limited pilot studies have been conducted. Specific concerns addressed in this study include fouling control, disinfection byproduct (DBP) precursor removal, biostability, and pathogen removal by IMSs. Pilot tests were conducted with advanced water treatment multi-objective IMSs. The information gained from these efforts provided direct comparison of potable water production via IMSs and conventional coagulation-sedimentation-filtration (CSF) treatment. Furthermore, IMSs were optimized in terms of configuration and operating condition. This paper presents preliminary results of IMS pilot testing. The objectives of the pilot investigations were: determination of productivity and water quality for different IMSs; determination of microbial rejection for varying microbes and membrane operating conditions; determination of consistency of IMS production; and, comparison of water quality for IMS and conventional surface water treatment. Includes 10 references, tables, figures.
