What Is Reverse Osmosis?

In simple terms, reverse osmosis is the process of pushing water through a filter that traps the impurities ( bacteria, virus, organic & inorganic impurities and other contaminates ) on one side and allows the pure water to be obtained from the other side. More formally, it is the process of forcing a solvent (water) from a region of high solute concentration (impurities) through a Thin film composite (TFC) with a size pore of 0.0001 micron membranes to a region of low solute concentration by applying a pressure. The membrane here is semi permeable, meaning it allows the passage of solvent (water) but not of solute (impurities). The membranes used for reverse osmosis have no pores; the separation takes place in a dense polymer layer of only microscopic thickness. In most cases the membranes is designed to only allow water to pass through.

Reverse Osmosis Process

Reverse Osmosis (R.O) is one of the most convenient and economical methods of reducing unwanted contaminants in your drinking water. Reverse Osmosis is the process by which water molecules are forced, by water pressure, through a semi permeable membrane. Most of the impurities and other contaminants are rinsed to the drain while the refined water is routed to a

The RO advantage

•  Purifies Water upto 99.9%.
•  Improves taste of water by removing salinity.
•  Makes water safe by removing finest impurities, Bacteria, Viruses and chemicals.
•  Storage tanks (wherever applicable) makes for Instant pure water.
•  Makes water pure and safe for drinking.
•  Makes water suitable for soaps, detergents, Clothes by reducing the hardness of the water.
•  Safe for babies as it removes hazardous chemicals from water.
•  Water can be used for medicines, baby food etc.
