Description:
This report summarizes the results of tests conducted to date at the EPA T&E Facility on the R3f filtration system utilizing fine beads (such as garnet beads or glass beads) and a conventional multimedia filtration system. Both systems have been designed and built by Enprotec, a water treatment company based in Hebron, KY. These systems were installed at the T&E Facility in August 2007 and tests were initially conducted to establish the optimum configuration of the R3f system. Subsequent tests sought to provide a comparative evaluation of the performance of the R3f system versus a conventional multimedia filtration system in meeting the SDWA drinking water standards, while qualitatively evaluating run times and the factors impacting the cost of filtration. The R3f system was also tested as a pre-treatment device for gross turbidity removal prior to polishing the water in a secondary filtration device such as fine pore-size bag filters, cartridge filters and ultrafiltration (UF) systems. Results of tests conducted on four different post-filtration devices – Harmsco cartridge filter, Rosedale bag filter, a Nanoceram cartridge filter and a low-cost UF system – are also summarized in this report. Finally, tests were also conducted using a germicidal UV lamp as tertiary treatment for virus and bacteria inactivation.
