The 1:1 units may only be operated with very soft or fully softened feed water.
The reverse osmosis system is ideally equipped to safely and easily remove the pollutants from tap water. The pre-filtration ensures particle- and chlorine-free water. In addition, volatile substances are bound (e.g. chlorinated hydrocarbons). Only after this high-quality pre-treatment does the water flow to the membrane. With the help of the water pressure, it is divided into a wastewater stream, in which all retained substances are removed, and a pure water stream (permeate). The permeate is stored in a pressure tank so that it is quickly available. The level of the tank is regulated with an electronical control. When the pure water is taken out through the drinking water tap, the water first flows through an activated carbon filter.
We all know osmotic processes. If you watch ripe black cherries it is possible that they will get ruptured or scared over places after a rain shower. The reason for it is the fact, that the skin of a cherry is a semipermeable membrane. Inside there is a solution with a high ionic concentration (cherry juice contains a lot of sugar and salts) and outside are rain drops with nearly no ions. The only way to balance the inside and outside concentrations is that water is flowing into the cherry - sugar and salts are too big to get through the cherry skin. But the cherry cannot grow so fast and therefore the inside migrating water raises the inside pressure - so called osmotic pressure - until the skin will rupture. With reverse osmosis techique the principle of osmosis is inverted. At the high concentration side (feed water, e.g. tap water) is a pressure (pump or tap water pressure) that forces the water molecules against their natural migration through the membrane onto the pure water side (permeate side). The salts (e.g. hardnes, nitrate, silicic acid, residues of pesticides and medicine) and other substances (except gases) are nearly not able to pass the membrane because they are too big. So on the permeate side is nearly only water. With the feed water a constant flow of new substances will reach the membrane. If you do not drain them they will accumulate and heavy soluble salts will precipitate. So a reverse osmosis unit will produce pure water (permeate) AND waste water (concentrate). |
