ENVIRONMENTAL TECHNOLOGY VERIFICATION REPORT - REMOVAL OF PRECURSORS TO DISINFECTION BY-PRODUCTS IN DRINKING WATER, PCI MEMBRANE SYSTEMS FYNE PROCESS MODEL ROP 1434 WITH AFC-30 NANOFILTRATON AT BARROW, AK - NSF 00/19/EPADW395
NSF International. ENVIRONMENTAL TECHNOLOGY VERIFICATION REPORT - REMOVAL OF PRECURSORS TO DISINFECTION BY-PRODUCTS IN DRINKING WATER, PCI MEMBRANE SYSTEMS FYNE PROCESS MODEL ROP 1434 WITH AFC-30 NANOFILTRATON AT BARROW, AK - NSF 00/19/EPADW395. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-03/014, 2000.
Equipment testing and verification of PCI Membrane Systems Inc. Fyne Process nanofiltraton systems Model ROP 1434 equipped with a C10 module containing AFC-30 tubular membranes was conducted from 3/16-5/11/2000 in Barrow, AS. The source water was a moderate alkalinity, moderately turbid surface water with a pH near neutral and a total organic carbon (TOC) concentration of approximately 15 mg/l. The average feed water temperature was 14.4C. The skid produced an average of 0.87 gpm of permeate when operated so that 80% 0f the raw water supplied to the test skid was recovered as permeate. The average transmembrane pressure and specific flux during the verification study were 88 psig, and 0.14 gfd/psi, respectively. The membrane removed more than 95% of TOC and reduced UV254 absorbance by an average of 97%. The test skid reduced the average total trihalomethane (TTHM) formation potential from 535 ug/l in the source water to 31 ug/l in the permeate. The average haloacetic acid (HAA5) formation potential was reduced from 398 ug/l in the source water to 6.2 ug/l in the permeate. All disinfection by-product formation potentials were evaluated using the U.S. EPA's Uniform Formation Conditions. The EPA Stage 1 Disinfectants/Disinfection By-Products (D/DBP) Rule requires TTHM and HAA5 concentrations not exceed 80 ug/l and 60 ug/l, respectively.
