An effluent treatment facility (F/H ETF) will begin operation at the Savannah River Plant (SRP) beginning November, 1988. The facility will treat low-level radioactive wastewater, primarily evaporator overheads. Currently this waste stream is diverted to seepage basins, however, once the F/H ETF is on line, it will be treated and discharged to an NPDES outfall. Treatment consists basically of microfiltration following pH adjustment, reverse osmosis (RO), and final polishing by cation exchange. Activated carbon columns were recently added to the treatment process between the filtration and RO steps to remove organic species, primarily tri-n-butylphosphate (TBP) and n-paraffinic hydrocarbons (NPH). This was done to ensure that discharge limits for oil and grease and biochemical oxygen demand (BOD) will not be exceeded and to protect the RO membranes, which experience an unacceptably rapid loss of flux due to fouling when treating waste streams containing these organics. The carbon columns will not be regenerated and the large volume of secondary waste associated with their disposal has led to investigations of alternative methods for organic removal that will minimize waste generation. 3 refs., 3 figs., 2 tabs.
