Performance Requirements for Reverse Osmosis Water Efficiency - Drinking Water

Residential Reverse Osmosis (RO) systems are used to treat drinking water. RO water treatment equipment reduces total dissolved solids, heavy metals, inorganics, and organics water contaminants. ROs are typically installed under the kitchen sink; however, countertop, wall mount, and free-standing models are also used in the market. ASSE/ANSI 1086 covers water efficiency, automatic shut-off valves, and flow restrictor requirements for Residential RO systems and performance testing to address the membrane life concerns of high efficiency RO membranes. This standard includes test requirements for complete systems or components (RO membrane, automatic shut off valve, flow restrictor).
