"A study was conducted to evaluate the rejection of six synthetic organic compounds (SOCs) from a potable water source by a nanoflltration membrane process. The SOCs were ethylene dlbromide (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 FllmTec 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), 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 on solutes." |
