A study evaluated the rejection of six synthetic organic compounds (SOCs) from a potable water source by a nanofiltration membrane process. The SOCs were ethylene dibromide (EDB), dibromochloropropane (DBCP), chlordane, heptachlor, methoxychlor and alachlor. To investigate SOC rejection, a membrane pilot plant was constructed that utilized a single, 4- by 40-inch FilmTec N 70 spiral wound, thin film composite membrane with a molecular weight cutoff of 300. The effects of different operating pressures and membrane feed stream velocities on membrane rejection of SOCs are reported. Trihalomethane formation potential (THMFP) and total organic halide formation potential (TOXFP) and general water quality in and out of the membrane are also reported. Accurate organic and inorganic mass balances were conducted in solutes.
