Water for Living CW5500 RO Membrane Specifications Background Reverse osmosis (RO) can be used to purify tapwater for drinking in homes. This application is generally referred to as "point of use" (POU). In addition to removing excess or harmful minerals, reverse osmosis removes odor, color, and other organic compounds, which contribute to bad taste or health concerns. Benefits of RO water include: · Safer drinking water: Consumers want safe, healthy, good-tasting water. RO purified water meets the requirements of the Safe Drinking Water Act and EPA standards for drinking water. · Good taste: RO removes excess minerals, odor, color, and other organic compounds that contribute to bad taste. · Health: RO membranes provide a barrier to bacteria and virus resulting in healthier water for drinking and cooking (better tasting coffee and other beverages, soups and water for general cooking). RO purified water is also better facial rinsing water. Products FILMTEC® Low-Pressure Reverse Osmosis Elements (28KB PDF) Nomenclature: (Example - TW30-XXYY-ZZ) TW30: Membrane is a tapwater type.
