The report covers a field study conducted at Fort Meade, Maryland, to determine the capabilitties of two water purification units for the removal of coliform organisms and a cultured virus (f2 bacteriophage) from Little Patuxent River water. The study was conducted in conjunction with the Johns Hopkins University Environmental Health Department. The results of this study indicate that the prototype reverse osmosis water purification unit employing cationic polymer addition, prefiltration, and hypochlorination and the standard water purification unit employing coagulation, filtration, and hypochlorination are both capable of effectively reducing the concentrations in a natural water of coliform organisms and f2 virus to undetectable levels. |
