A reverse osmosis (RO) bench-scale test and feasibility study was completed for the city of Hutchinson, Kansas, to evaluate the technical feasibility and cost of various RO pretreatment options and to recommend an approach to pilot testing for converting remediation groundwater into beneficial reuse as a drinking water supply. Use of RO in the remediation treatment process presents a novel approach to solving water supply and groundwater contamination issues faced by many cities in the Midwest. However, selecting the appropriate RO pretreatment method is considered critical to achieving long-term, reliable, and cost-effective RO operations with minimal membrane fouling. The groundwater, which was contaminated by various industrial activities, contains low levels of chlorinated solvents and relatively high concentrations of total dissolved solids, chloride, and inorganic membrane foulants. The most common and widely used method for removing chlorinated solvents from contaminated groundwater is air stripping. However, use of an air stripper ahead of RO enhances the potential for iron and biological fouling of the membranes. As an alternative, an air stripper could be placed after the RO system. In this case, the primary concern is the compatibility of chlorinated solvents on the membrane surface. To assess RO fouling concerns and assist with pilot test planning, a detailed evaluation and comparison of various RO pretreatment methods and water chemistries for systems that incorporate air stripping for VOC-removal as both a pre-RO and post-RO treatment step was completed. The results of this side-by-side comparison of cost and performance issues, as well as the results of a RO bench-scale test, are presented to show that RO can be cost-effectively applied in the remediation process for beneficial reuse of contaminated groundwater for drinking water supply.
