This paper presents the results of a pilot study that employs a unique hollow fiber and system design for the recovery of primary filter backwash water from a municipal water plant. Study objectives were to: evaluate the treatment of Ingram's Mill backwash water with hollow fiber ultrafiltration to produce (permeate) water having effective particle reduction, turbidity less than 0.5 NTU's, and a 4-log reduction of Giardia and Cryptosporidium from the incoming-backwash water; establish membrane system operating parameters such as flow rates, system backwash cycle, and cleaning schedule on the backwash-feed water; challenge the membrane system during the test period, with higher particle counts than otherwise will be seen with a full-scale production plant to determine any limitations in the membrane separation process; and, produce sufficient and consistent data, for the purpose of designing a commercial hollow fiber ultrafiltration system. Includes 2 references, table, figures.
