Reverse Osmosis Systems for Process & Drinking
Reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration when no external pressure is applied. The membrane here is semipermeable that allows the passage of solvent but not of solute.

Our Eco water's reverse osmosis systems possess highest quality components. These systems are designed to emphasize most on functioning, affordability, easy operation and system expandability.



Our Reverse osmosis treatment plants produce high quality permeate water from seawater, municipal and well water. The production rate is based on feed water at 25°C, with turbidity of less than 1 NTU, silt density index (SDI) of less than 5. The sea water RO systems are designed for a total dissolved solids of 36,000.

The reverse osmosis process uses semi permeable spiral wound membranes to separate and remove dissolved solids, organic, pyrogens, sub micron colloidal matter and bacteria from water. Feed water is delivered under a pressure of approximately 16 kg/cm2 through reverse osmosis membranes. Water permeates the minute pores of the membrane and is delivered as purified water. Impurities in the water are concentrated in the reject stream and flushed to drain. Reverse osmosis is capable of removing 90-99% of total dissolved solids (TDS), 99% of organic, including pyrogens, and 99% of all bacteria in the feed water.



The impurities are concentrated as the feed water passes through the reverse osmosis system and flows over the membrane. Impurities removed from the feed water are concentrated in the concentrate, or the reject stream. As impurities concentrate, they may reach saturation and precipitate. The operator must be certain that impurities in the feed water are not concentrated enough in the RO membranes to cause precipitation because precipitation can ruin the membranes.
