Systems of the return osmosis, Filters of the return osmosis
The most progressive systems of preparation of drinking water are the obratnoosmotichesky systems giving water at the exit on degree to cleaning close to thawed snow of glaciers now. Water at the exit of the return osmosis possesses fine tastes. It is used without preliminary boiling.
Key a component of such system - the semipermeable membrane providing extent of water purification to 98-99% concerning almost any pollutants. The membrane passes through itself only molecules of water and oxygen, filtering all harmful impurity. The characteristic size of a time of a membrane - 1 Angstrom (10-10 m). Thanks to such cleaning from water the dissolved inorganic and organic compounds, and also heavy metals, bacteria and viruses are removed.
Major factor for the correct operation of the filter on the basis of the return osmosis is existence in your water supply system of pressure not lower than 2,8 atmospheres. If pressure needs to be chosen the filter less with a pomp (pump) which forces the necessary pressure.
