Impact/Purpose:
This report documents the results of tests conducted on four filtration systems for the removal of turbidity, color, organic matter, microorganisms and their surrogates from surface water.
Description:
The U.S. Environmental Protection Agency (EPA) National Risk Management Research Laboratory (NRMRL) evaluated various filtration systems at the EPA T&E Facility in Cincinnati, Ohio and at a field site in Ely, Minnesota (MN) in collaboration with the Minnesota Department of Health (MDH). Color and organic matter are often present in lake water and these constituents are difficult to remove using conventional treatment technologies. The organic matter can also serve as a precursor to the formation of disinfection byproducts (DBPs). This report documents the results of tests conducted on the following four filtration systems for the removal of turbidity, color, organic matter, microorganisms and their surrogates from surface water: 1) Fyne Technology units manufactured by ITT Corporation (Zelienople, PA) that incorporate tubular membranes which are periodically cleaned by a foam-ball 2) GE Pentair unit that utilizes capillary hollow fiber membranes 3) Virex Pro unit manufactured by Seccua GmbH (Steingaden, Germany) that consists of hollow fiber membranes in a stainless steel housing. 4) A radial flow fluidized filtration (R3f) unit followed by polishing membrane filters (microfilter and ultrafilter modules manufactured by NOK).
