Full Description

A full-scale (8-cubic feet/second) reverse osmosis (RO) water treatment plant equipped with conventional cellulose acetate (CA) membranes, and two pilot RO plants, equipped with polyamide (PA) membranes, were tested for their ability to remove total organic carbon (TOC) and a broad range of trace organics, including volatiles, purgeables, neutrals, bases, phenols, and acids from lime-clarified secondary municipal wastewater. Total organic carbon was removed to the extent of 89 percent by the CA membrane and to 99 percent by the two PA membranes. The three membranes tested removed trace organics to varying degrees, depending on the structural features of the compounds, such as charge, size, and branching. Ranges of removals of volatiles, purgeables, and extractables by the full-scale RO plant at 84 percent water recovery were 53-87 percent, 0-100 percent, and 73-
