The process of Reverse Osmosis reverse osmosis process uses a semi-permeable membrane to separate and remove dissolved solids, organic, pyrogenic, colloidal matter, submicro-organismos, viruses, and bacteria from the water. The process is called reverse osmosis since it requires pressure to force pure water through a membrane, leaving impurities behind. Reverse osmosis is capable of removing 95% – 99% of total dissolved solids (TDS) and 99% of all bacteria, thus providing a safe, pure water. Reverse osmosis is a procedure that ensures the physical, chemical and bacteriological water desalinator treatment. It works by semipermeable membranes of polyamide, coiled spiral, which act as filter, retaining and eliminating most of the salts dissolved at the time that prevent the passage of bacteria and viruses, resulting in a pure and sterile water. Water with a high content of salts such as sodium, calcium, boron, iron, chlorides, sulfates, nitrates and bicarbonate, can be treated with reverse osmosis until reaching the limits considered acceptable water for their use. The multiple advantages of osmosis reverse domestic include the following:-savings in the purchase of bottled water, without leaving the comfort of home nor charge with heavy carafes, bottles or cans. -Drinking water of the highest quality, crystal clear and fresh, within reach of your faucet. -Transparent and well flavored ice cubes. -Healthy and safe for the baby bottles. -Coffees and infusions of pure flavors. -Cooking vegetables, Rices, pastas and soups with perfect water. -Essential for low sodium diets and slimming diets. -Ideal use with delicate plants, aquariums and steam irons.
