Reverse osmosis (RO) is a technique for removing dissolved solids and pollutants from water by passing water through a semi-permeable RO membrane that enables water to flow through but leaves the bulk of dissolved particles and some other contaminants behind. In order for RO membranes to function, water must be under high pressure. The “permeate” refers to the water that goes through the RO membrane, while the “concentration” refers to the soluble substances that are refused by the RO membrane. A correctly functioning RO system may remove up to 99.5 percent of dissolved salts and contaminants from the water. Reverse osmosis can remove 99 percent or more of dissolved salts (ions), particles, colloids, organics, microorganisms, and pyrogens from the feed solution. Contaminants are rejected by a RO membrane based on size and charge.
LARCO India provides commercial reverse osmosis (RO) water treatment systems that transform high TDS water into low TDS water. Most of the time, water from bore wells and other sources includes a high level of dissolved salt, making it unsuitable for drinking and a variety of other uses. We supply Ro plants ranging from 50 LPH to 50 m3/hr.
