AWWA ACE59928

The qualitative and quantitative impact of process finished water quality was investigatedas part of a large-scale investigation on the effect of blending different finished waters ondistribution system water quality. This work was supported by the American Water Works Association Research Foundation and Tampa BayWater. Cu and Fe release was accessed for varying water quality and pipe materials in pilotdistribution systems (PDSs) that were made from unlined cast iron (UCI), ductile lined iron(LCI), polyvinyl chloride (PVS), and galvanized steel (G) pipes taken from actual distributionsystems. After one year of work, field results demonstrated that nanofiltration of a pretreatedsurface or a blend of softened ground, coagulated surface or desalinated waters released lesscopper and iron than finished water produced by enhanced coagulation or lime softening. Includes 9 references, tables, figures.
