Analysis of weekly samples from the F- and H-area treblers indicates that tri-n-butylphosphate (TBP) is the major organic species in the feed to the F/H Effluent Treatment Facility (ETF). Concentrations up to 100 mg/L were observed, with an average of 50 mg/L from F-area and 3 mg/L from H-area. Normal paraffinic hydrocarbons (NPH) are present in lesser amounts, ranging up to 4 mg/L. These two species, both foulants of the reverse osmosis (RO) membranes, account for almost all of the dissolved organic carbon present in the samples. Samples from the sources which feed the treblers (and will feed the ETF) indicate that all eight canyon evaporators contribute TBP. None of the four tank farm evaporators contribute TBP. If TBP is to be removed at the sources, either the overhead streams from a number of evaporators will have to be piped to one or two central locations for treatment, or up to eight individual treatment points would have to be maintained. 6 refs., 5 tabs.
