Remediating biofouling of reverse osmosis membranes
Several potential additives and the use of influent pH adjustment were examined to remediated the biofouling problem of the ETF reverse osmosis (RO) system. Tests were conducted with simulated RO feed containing salt, metal hydroxides and bacteria. The addition of sodium hexametaphosphate (SHMP), sodium bisulfite, and adjusting the influent pH to 3 were each successful in reducing the RO biofouling. Little or no benefit was found from the use of a biofilm remover (Filmtec Alkaline Cleaner) or the use of surfactants (Surfynol or sodium lauryl sulfate). In addition, Surfynol use resulted in irreversible fouling and necessitated membrane replacement. At the water recoveries used in the ETF (>90%), sodium bisulfite addition resulted in the recovery of 70--90% of the flux and almost complete restoration of the DF to prefouled conditions. Based on the bench-scale tests completed, IWT would recommend that sodium bisulfite addition be tested at the ETF. This testing would involve optimizing the amount of bisulfite required. In addition, it is recommended that the addition of SHMP or influent pH adjustment be evaluated since the relative differences in labscale tests were small and scale-up effects could be present. The ETF operating permit allows each to be added.

Reverse osmosis performance with solutions containing tri-n-butyl phosphate
Tests were conducted to determine whether the reverse osmosis (RO) units at the F/H Effluent Treatment Facility (ETF) at the Savannah River could be made to process solutions containing tri-n-butyl phosphate (TBP). It was desired to test whether operation at a feed pH other than neutral would improve performance. Test results are discussed in this report and indicate that little improvement in the water flux can be expected at other pH values.
