This paper describes a two-year research project at the University of Illinois at Urbana-Champaign that consisted of constructing a pilot plant that could be operated in the form of a feasibility study. During the first year, various components of the ultrafiltration (UF) and reverse osmosis (RO) pilot plants were acquired and assembled into one full system. Both pilot systems were to be outfitted with electrical transducers and controls and coordinated using LabView software for remote operation and control. Testing protocol was developed that allowed for comparison of results with the Electric Power Research Institute (EPRI) and other studies in the area of nitrate removal. Three facilities, consisting of reverse osmosis, ion exchange, and biological denitrification, could then be evaluated for cost and efficiency of contaminant removal. This goal was met by obtaining seven different RO membrane elements. A laboratory regime was also set up to measure important water quality parameters throughout the pilot study. Includes 60 references, tables, figures.
