RO units are completely assembled and shipped ready for a trouble-free installation and start up. All units are factory tested prior to delivery to ensure quality and performance.

Reverse osmosis is considered one of the very best method for purifying water. Reverse osmosis water purification is a water treatment process whereby virtually all particles, contaminants, and even dissolved material, such as sodium, chloride, fluoride, calcium carbonate, calcium sulfate, and many others, may be separated from water. The reverse osmosis process forces the water through an ultra-fine semi-permeable membrane under high pressure. The water diffuses through the membrane and the dissolved salts remain behind on the surface of the membrane. Water that makes it through the membrane is considered completely pure, while water that does not make it through, is sent through a drainage tube and is rendered impure.
