Drinking Water System

Reverse osmosis systems push purified water through a semi-permeable membrane. The membrane itself removes inorganic chemicals, sediment, and high molecular weight organics from the water. These systems also include sediment and carbon filters to catch contaminants before and after the membrane itself. As a system, the remove many common inorganic and organic contaminants, sediment, and odor. The point of use system is smaller and is intended to purify small volumes of water. Typical applications are drinking water and humidification. About 50-300 gallon per day systems are used. A surge tank is often supplied for peak flows, membranes are under-rated for cold water less than 77 F and over-rated above 77 F. Even though the RO membrane will reject microbes, these systems do not meet disinfection standards.
