Reverse Osmosis (RO) systems is a revolutionary new way and is faster than most systems today. The RO process uses a semi-permeable TFC membrane to remove 99% of impurities and contaminants such iron, lead, nitrate, magnesium, copper, bacteria, virus etc from water.
We offer RO Systems for both the residential and commercial customers. All our RO Systems have been individually wet tested and sanitized prior to shipment.
- R.O. Systems Residential: Residential line of RO Systems are an excellent source of water for drinking, cooking, coffee & tea, pets & plants, homes, offices, restaurants, pharmaceutical applications, etc. Custom designing and labelling is also available. To know more about the various kinds of residential systems we offer, Click Here.
- R.O. Systems Commercial: The new comercial series of RO Systems offers superior standard features and high quality. To know more about the various kinds of commercial systems we offer, Click Here.
- How Reverse Osmosis Works
A semi-permeable membrane, like the membrane of a cell wall or a bladder, is selective about what it allows to pass through, and what it prevents from passing. These membranes in general pass water very easily because of its small molecular size; but also prevent many other contaminants from passing by trapping them. Water will typically be present on both sides of the membrane, with each side having a different concentration of dissolved minerals. Since the water is the less concentrated solution seeks to dilute the more concentrated solution, water will pass through the membrane from the lower concentration side to the greater concentration side. Eventually, osmotic pressure will counter the diffusion process and a equilibrium will form.
RO forces water with a greater concentration of contaminants (the source water) into a tank that contains water with an extremely low concentration of contaminants (the processed water). High water pressure on the source side is used to "reverse" the natural osmotic process, with the semi-permeable membrane still permitting the passage of water while rejecting most of the other contaminants. The specific process through which this occurs is called ion exclusion, in which a concentration of ions at the membrane surface from a barrier that allows other water molecules to pass through while excluding other substances.
Semi-permeable membranes have come a long way from the natural pig bladders used in the earlier osmosis experiments. Before the 1960's, these membranes were too inefficient, expensive, and unreliable for practical applications outside the laboratory. Modern advances in sythetic materials have generally solved these problems, allowing membranes to become highly efficient at rejecting contaminants, and making them tough enough to withstand the greater pressures necessary for efficient operation.
Even with these advances, the "reject" water on the source side of a Reverse Osmosis (RO) system must be periodically flushed in order to keep it from becoming so concentrated that it forms a scale on the membrane itself. RO system also typically require caron pre-fileter for the reduction of chlorine, which can damage an RO membrane; and a sediment pre-filter is always required to ensure that fine suspended materials in the source water do not permanently clog the membrane. Hardness reduction, either through the use of water softening for residential units or chemical softening for industrial use, may also be desirable in hard water areas.
