Microbiological Water Purifiers

Microbiological water purifiers use chemical, mechanical, and/or physical technologies to filter and treat waters of unknown microbiological quality, but are presumed to be potable. This protocol addresses systems having a flow rate of 5 gpm or less and contains minimum requirements for materials, design and construction, and performance of these systems. The systems are not intended to convert wastewater or raw sewage into drinking water. System components covered under other NSF or NSF/ANSI standards or criteria shall also comply with the requirements contained in those other standards. This protocol shall in no way restrict new system designs, provided such designs meet the minimum specifications described herein.
