Reverse Osmosis Water

March 4, 2019 Comments Off on Reverse Osmosis Water

The reverse osmosis process uses a semi-permeable membrane to separate and remove dissolved solids, the organic, the pyrogens, colloidal matter submicroorganisms organisms, viruses, and bacteria from the water. The process is called reverse osmosis since it requires pressure to force pure water through a membrane, exiting; the impurities behind. Reverse osmosis is capable of removing 95% – 99% of total dissolved solids (TDS) and 99% of all bacteria, thereby providing a safe, pure water which is reverse osmosis 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 bicarbonates, can be treated with reverse osmosis until reaching the limits considered acceptable water for their use. Filter membranes are the key and responsible for separating the salts in the water. Such membranes can be considered molecular filters.

The size of the pores of these filters membranes is extremely small, so it requires a considerable pressure to pass amounts of water through them. The choice of the most appropriate membrane model is according to the water to be treated and their subsequent employment, determining the most suitable installation type. Dirt remaining in the membranes are subsequently dragged and washed by the same current of water. In this way the system performs a constant clean. This stream of waste water required, is in direct relation with the type of membrane that is used and its demands. Original author and source of the article.
