The City of Pierre, SD currently has a water supply that consists of minimally treated groundwater, which has high hardness, total dissolved solids and manganese. The City conducted a facility plan to evaluate potential source water and treatment alternatives for their water system. The recommended source and treatment alternative featured a surface water treatment plant and raw water intake on the Missouri River. The proposed water treatment plant would rely on ultrafiltration (UF) technology as the key process in the water treatment schematic. To ensure the technology was suitable for the source water quality in Pierre, the City elected to conduct pilot studies on multiple UF technologies. The City opted to pilot three separate UF systems; a polymeric pressurized system, a polymeric immersed (suction) system, and a ceramic pressurized system. Without existing infrastructure to house the pilot units or tap off an existing raw water line, the pilot featured a unique setup near the banks of the river which required construction of an enclosed and secure pilot facility along with permits for temporary construction of a raw water intake, temporary water use, and temporary discharge. The results of the pilot study revealed interesting data, discussed within this presentation, and ultimately concluded that all membrane technologies piloted would be suitable UF systems for full-scale installation.
