WSD residential series membranes are fully capable of removing the organic matter in water, microorganisms, viruses, metal ions, radioactive ions, carcinogens, scale, heavy metal ions, and other harmful substances. Majority of dissolved salt ions and pollutants cannot penetrate the membrane, but water molecules can pass through and allow drinking water for house.
