Membrane filtration systems generate several waste streams, including a waste washwater flowthat is approximately 10 percent of the total plant treated water production. Provisions forhandling the waste streams can have a significant impact on the capital and operating costcharacteristics and viability of the treatment plant.Using the design of United Water Idaho's new 6 mgd Columbia Water Treatment Plant (WTP) as a case study, five basicalternatives for waste washwater handling that are typically available to most municipal treatmentfacilities are presented. This paper discusses the capital cost, power, staffing, maintenance, chemical, space,permitting, reliability, and operational flexibility considerations of each alternative, along with the potential for impacts to water quality or membrane performance. Thepaper concludes with the selected approach for the Columbia WTP. Includes tables, figures.
