The purpose of this project was to determine the effects that tributyl phosphate (TBP) would have on a polysulfone crossflow ultrafilter. Aqueous simulant solutions containing TBP (100 or 1000 mg/L) and Fe(III), Si(IV), Al(III), and NaNO{sub 3} were examined. Results obtained from simulant solutions containing 100 mg/L TBP were virtually identical to those obtained in the absence of TBP. However, a solution containing higher concentrations of TBP (1000 mg/L) very rapidly reduced the permeate flow rate to nearly zero. Chemical cleaning was successful in restoring initial flow rates. Permeate flux was plotted as a function of transmembrane pressure for clean …

Description
The purpose of this project was to determine the effects that tributyl phosphate (TBP) would have on a polysulfone crossflow ultrafilter. Aqueous simulant solutions containing TBP (100 or 1000 mg/L) and Fe(III), Si(IV), Al(III), and NaNO{sub 3} were examined. Results obtained from simulant solutions containing 100 mg/L TBP were virtually identical to those obtained in the absence of TBP. However, a solution containing higher concentrations of TBP (1000 mg/L) very rapidly reduced the permeate flow rate to nearly zero. Chemical cleaning was successful in restoring initial flow rates. Permeate flux was plotted as a function of transmembrane pressure for clean water before and after the filter had been exposed to TBP. Also, the axial pressure drop was plotted as a function of the Reynolds numbers. Linear correlation of these data suggested that the filter did not swell or become distorted. Therefore, it was concluded that TBP does not have a permanent effect on this polysulfone ultrafilter. 6 refs., 7 figs., 1 tab.
