Full Description

There is little question that membrane technology is the wave of the future in terms ofdrinking water treatment and pathogen protection. In addition, membrane systemsare becoming more cost-effective each day, and when life-cycle costs are considered,low-pressure membranes are often less expensive than traditional water treatmenttechnologies.For most surface water systems, the most appropriate membrane applications are low-pressure membranes, including micro- and/or ultrafiltration. One common concern withlow-pressure membranes is their ability to remove dissolved organic matter and thecorresponding organic fouling of the membrane material. The removal of organicmaterial is critical for many water systems considering the passage of the Stage 1Disinfectants/Disinfection By-Product (D/DBP) Rule.Accordingly, this paper discusses the results of a side-by-side pilot study performed byHDR Engineering, Inc. and the Town of Wadesboro, NC to evaluate thefeasibility of low-pressure membranes for an expansion of its water treatment plant andfor compliance with the Stage 1 D/DBP Rule. Includes tables, figure.
