Objectives were to demonstrate Seeded reverse osmosis (SRO) effectiveness in concentrating typical power plant wastewaters and to develop an economic comparison of SRO with other wastewater concentration technologies. Researchers transported a previously fabricated SRO pilot unit to the Utah Power and Light Company Hunter Station for a three-phase field study. In the first phase, they operated the SRO pilot unit to recover 80% of a cooling-tower blowdown feed. During the second phase, the SRO pilot unit recovered 65% of a flue gas desulfurization (FGD) thickener overflow feed. In the third and final phase, researchers reconfigured the SRO pilot unit to evaluate simultaneously the performance of five tubular, cellulose-acetate membranes provided by four manufacturers. Using field test results, the team then completed an economic analysis comparing SRO with other wastewater treatment processes. The SRO pilot unit membranes showed no signs of fouling from inorganic scaling throughout all three phases of the field testing. However, the membranes experienced a rapid deterioration during the first two test phases. 7 refs., 37 figs., 21 tabs.
