Abstract

In previous research, reverse osmosis treatment of a ferrous iron mine discharge at Mocanaqua, Pennsylvania was studied. Using a tubular system, a loss of 90 percent of the original product flow in 400 hours of operation due to iron fouling was observed. Though sodium hydrosulfide flushes were successful in flux restoration, fouling immediately recurred upon resumption of operation on the ferrous water. To investigate the Mocanaqua fouling phenomena, field studies were undertaken. Reported are the results of the tests and comparisons with a spiral wound and hollow fiber reverse osmosis unit studied at the same time.
