Description:
A multi-layer, cartridge-based system that combines physical filtration with carbon adsorption and ultraviolet (UV) light disinfection has been developed to perform as a water treatment security device to protect homes against accidental or intentional contaminant events. A series of laboratory experiments was conducted to evaluate the baseline performance of the system in removing physical and biological contaminants and to identify potential areas of further improvement. The tests were conducted at the U.S. Environmental Protection Agency (EPA) Test and Evaluation (T&E) Facility in Cincinnati, Ohio. The system was challenged with test water containing different levels of turbidity and a number of biological contaminants including B.subtilis, E.coli, MS2 bacteriophage and Polystyrene Latex (PSL) beads as a surrogate for Cryptosporidium. The data demonstrated that the performance of the system varied depending on the contaminant or surrogate used for the study. The aerobic spore B.subtilis was found to be a conservative surrogate for Cryptosporidium in comparison with PSL beads.
