Above-mentioned EDI (Electrodeionization, electrodeionization technology) is a kind of pure water manufacturing technology that ion exchange technique, ion-exchange membrane technique and ion-conductance migrating technology are combined.It is that electrodialysis and ion exchange technique are combined, and utilizes two end electrodes high pressure that charged ion in water is moved, and coordinates ion exchange resin and selective resin film to move removal with speeding-up ion, thereby reaches 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 see through ion, and wherein anion-exchange membrane only allows negatively charged ion to see through, and does not allow positively charged ion to see through; And cationic exchange membrane only allows positively charged ion to see through, do not allow negatively charged ion to see through.Between a pair of anion and cation exchange membrane, filling mixture iron exchange resin has just formed an EDI unit.The space being occupied by mixture iron exchange resin between anion and cation exchange membrane is called as freshwater room.The EDI unit of some amount is enumerated together, made anion-exchange membrane and cationic exchange membrane alternative arrangement, add special ion exchange resin between ion-exchange membrane, the space of its formation is called as dense hydroecium.Under the promotion of given volts DS, in freshwater room, zwitterion in ion exchange resin moves to positive and negative electrode respectively, and enters dense hydroecium through anion and cation exchange membrane, and the ion in feedwater is adsorbed by ion exchange resin and occupies because ion-conductance moves the room staying simultaneously.In fact the migration of ion and absorption are simultaneously and recur.By such process, the ion in feedwater enters into dense hydroecium through ion-exchange membrane and is removed and becomes de-mineralized water.
Above-mentioned reverse osmosis membrane device is to utilize impressed pressure, makes the water in strong solution overcome the osmotic pressure of organic cellulose semi-permeable membranes and be penetrated into dilute side, reaches the device that makes water desalination, desalination.Be called for short RO (Reverse Osmosis Unit).Reverse osmosis is the most accurate embrane method liquid separation technology, applying working pressure in water inlet (strong solution) side presses to overcome naturally osmotic, when the flow direction of the working pressure of pressing higher than naturally osmotic water molecules naturally osmotic when being added on strong solution side will reverse, 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 allows water molecules to see through, and 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, refers 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 that flow down from above are dispersed into many shallow bids or drops, the air blasting from bottom and water have very large contact area, and the pressure component of airborne carbonic acid gas is very low, like this, just the carbonic acid gas desorbing from water is taken away very soon.Water, by air blast de-carbon, can be down to the content of carbonic acid gas below 5mg/L.Its simple point of telling the truth is exactly that the content of gas dissolved water is directly proportional with the air content pressure component contacting with him, 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.
