Effect of Potassium Chloride on the Virucidal Effectiveness of Chlorine Disinfection for Military Needs. Phase 1

Abstract

The military looks to disinfection with free chlorine (FC) as the final barrier to prevent viruses and other pathogenic microorganisms from producing disabling enteric diseases in military personnel who must drink field- produced drinking water. The disinfection barrier is paramount in all of the variety of conditions under which the military must produce drinking water in the field. This study was divided into two phases, PHASE 1 was to determine whether KC1 (C1- in the range of 10 to 600 mg/L) has a significant effect (2 to 3-fold difference) on disinfection by the free chlorines. In the event that a significant KC1 effect was demonstrated, PHASE 2 was to be initiated to provide comprehensive data on the adjustment of FC that will be necessary to meet the military's required disinfection capability or to develop cautionary guidance for field disinfection at low K+ and/or C1- levels (for example, ROWPU operations). Keywords: Reverse Osmosis Water Purification Unit(ROWPU); Drinking water.
