Above-mentioned EDI (Electrodeionization, electrodeionization technology) is a kind of pure water manufacturing technology ion exchange technique, ion exchange membrane technology and ion-conductance migrating technology combined.It is combined at electrodialysis and ion exchange technique, utilizes two end electrodes high pressure that charged ion in water is moved, and coordinate ion exchange resin and selective resin film to move removal with speeding-up ion, thus reach the object of desalt.The ultimate principle of EDI equipment: the principle of work of ion-exchange membrane and ion exchange resin is close, can optionally through ion, and wherein anion-exchange membrane only allows anion-permeable, does not allow cation permeable; And cationic exchange membrane only allows cation permeable, do not allow anion-permeable.Between a pair anion and cation exchange membrane, filling mixture iron exchange resin just defines an EDI unit.The space occupied by mixture iron exchange resin between anion and cation exchange membrane is called as freshwater room.Enumerate together by the EDI unit of some amount, anion-exchange membrane and cationic exchange membrane are alternately arranged, add special ion exchange resin between ion-exchange membrane, its space formed is called as dense hydroecium.Under the promotion of given volts DS, in freshwater room, zwitterion in ion exchange resin moves respectively to positive and negative electrode, and enters dense hydroecium through anion and cation exchange membrane, and the ion simultaneously in feedwater is adsorbed by ion exchange resin and occupies the room stayed due to ion-conductance migration.In fact the migration of ion and absorption are simultaneously and recur.By such process, the ions across ion exchange membrane in feedwater enters into dense hydroecium and is removed and becomes de-mineralized water.
Above-mentioned reverse osmosis membrane device utilizes impressed pressure, makes the water in strong solution overcome the osmotic pressure of organic cellulose semi-permeable membranes and penetrate into dilute side, reach the device making water desalination, desalination.Be called for short RO (Reverse Osmosis Unit).Reverse osmosis is the most accurate embrane method liquid separation technology, working pressure is applied to overcome naturally osmotic pressure in water inlet (strong solution) side, when the working pressure higher than naturally osmotic pressure will reverse from the flow direction of water molecules naturally osmotic when being added on strong solution side, water is produced in the purification that the water molecules part in water inlet (strong solution) becomes dilute solution side by reverse osmosis membrane device; Reverse osmosis equipment can stop the organism that all solvability salt and molecular weight are greater than 100, but allow water molecules through, reverse osmosis composite membrane ratio of desalinization is generally greater than 98%.
The principle of work of above-mentioned TOC carbon dioxide cleaner (TOC is wherein model) is refer to that water enters from the top of carbon dioxide cleaner, under distribution apparatus drenches, after packing layer, enters water tank from bottom.In carbon dioxide cleaner, due to the barrier effect of filler, the current flow down from above are dispersed into many shallow bids or drops, the air blasted from bottom and water have very large contact area, and the pressure component of carbonic acid gas in air is very low, like this, just the carbonic acid gas desorbed from water is taken away very soon.The content of carbonic acid gas, by air blast de-carbon, can be down to below 5mg/L by water.Its simple point of telling the truth is exactly that the content of gas dissolved water and the air content pressure component that contact with him are directly proportional, and it is similar that the air suspended type of this principle and power plant removes oxygen principle of work.UV sterilizing unit is a kind of known sterilizing unit, as ultraviolet sterilization apparatus etc.
