Two Koch Membrane Systems HF-82-35-PMPW UF membrane cartridges were tested for removal of viruses, bacteria, and protozoan cysts at NSFs Drinking Water Treatment Systems Laboratory. The testing was conducted as part of a series of ETV verifications of the US Navy Office of Naval Researchs Expeditionary Unit Water Purifier (EUWP), manufactured by Village Marine Tec. The tests reported herein served to demonstrate the performance of the Koch Membranes Targa-10-48-35-PMC UF membrane cartridge used in the EUWP. The Targa-10-48-35-PMC is a larger version of the HF-82-35PMPW; both cartridges are made with the same UF membrane fibers. For this verification, the HF-8235- PMPW was operated at a target flux of 40 gallons per day per square foot (gfd), which is the operating flux of the Targa-10-48-35-PMC in the EUWP. This verification did not address long-term performance, membrane cleaning, or full-scale field maintenance and operation issues. These items will be addressed in the verification reports for the full EUWP. The UF cartridges were challenged with approximately 5 log10 of the bacteriophage viruses fr and MS2, 7 to 8 log10 of the bacteria Brevundimonas diminuta, and 5.7 log10 of live Cryptosporidium parvum oocysts. The bacteria and viruses used in this study served as surrogates for pathogenic bacteria and viruses that may be introduced into drinking water through accidental or intentional contamination. Each challenge was 30 minutes in length. The membranes removed a minimum of 4.8 log10 of the viruses, 6.0 log10 of B. diminuta, and 5.7 log10 of C. parvum.
