Reverse Osmosis is the latest technology to remove all excess Total Dissolved Solids (TDS), Chemicals in water upto 95%. It removes Bacteria and Virus to a level of 99% , Other Purification method has no effect on TDS level of water. The water coming out of the systems is pure, clean, safe, odour free, sparkling fresh, refreshing, healthier and most of all Great tasting water for diets, baby formula, coffee, tea, hard drinks, refreshment drinking water, ice cubes, cooking, washing vegetables, aquariums, pets and lots of other applications. How the Reverse Osmosis System Works? Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. These impurities and contaminates are flushed down the drain. Ultimately, the factors that affect the performance of a Reverse Osmosis System are: Incoming water pressure Water Temperature Type and number of total dissolved solids (TDS) in the tap water The quality of the filters and membranes used in the RO System (see operating specs).
