AWWA WQTC69403

A pilot study was conducted on source water in Texas with high turbidity, high color andhigh organic contents. The treatment scheme included pretreatment with chlorine dioxide, PACland sodium permanganate. The pretreated water was then sent to a conventional clarifier withplates. The coagulated and clarified water was filtered using microfiltration/ultrafiltration (MF/UF) membranes. Similarpretreatment was used for ceramic membranes and water quality performance of ceramicmembranes was compared with polymeric membranes in terms of turbidity, color and organicsremoval. The ceramic membranes were operated in dead-end and cross flow filtration mode.Experiments were conducted to determine optimum pretreatment for ceramic membranes.The preliminary results showed ceramic membranes are comparable to polymericmembranes under similar conditions in terms of organic and turbidity removal. The permeabilityrates of ceramic membranes are superior to the permeability rates of polymeric membranes.Ceramic membrane performance was independent of the mode of operation. Includes tables, figures.
