EDI (Electrodeionization) is also called continuous electric desalination technology. It scientifically integrates electrodialysis technology and ion exchange technology, through the selective permeability of cation and anion membrane to cation and anion, and ion exchange resin to exchange ions in water. Under the action of the electric field, the directional migration of ions in water is achieved to achieve the deep purification and desalinization of water, and the hydrogenated ions and hydroxide ions generated by water electrolysis are used to continuously regenerate the filling resin. Therefore, the EDI water production process does not require Acid and alkali chemicals can be continuously produced to produce high-quality ultra-pure water. It has the advantages of advanced technology, compact structure, and easy operation. It can be widely used in the fields of power, electronics, medicine, chemical, food and laboratory. Green revolution in processing technology. The effluent water quality has the best stability.

| Water tank | Storage water, Built-in stainless steel float ball valve and inlet water level sensor to maintain the normal water level of the tank. |
| Water pump | In order to ensure the system water supply flow and pressure balance set |
| Quartz sand filter(stainless steel 304 or FRP material) | It is mainly used to filter solid substances in water, and the filter medium is generally quartz sand. It has the characteristics of high strength, long life and stable water quality. It is an indispensable pretreatment equipment for reverse osmosis, electrodialysis and ion exchange |
| Activated carbon filter (stainless steel 304 or FRP material) | It can remove harmful humic acid, fulvic acid, lignoflavic acid and other organic matter in water. Usually can remove 60% to 80% of the colloidal material; 47% to 60% organic matter. |
| Softener(stainless steel 304 or FRP material) | It removes calcium and magnesium ions that form scale in hard water. |
| Security filter | The third stage filtration is carried out on the reverse osmosis system water, the purpose is to reduce or eliminate the filter material particles leaked out of the pre-treatment equipment to play a final protective role, to ensure that the final water into the reverse osmosis system meets the requirements. |
| High pressure pump | In order to ensure the system water supply flow and pressure balance set. |
| Reverse osmosis system | The reverse osmosis device in the system uses the world's most advanced polyamide composite membrane element as the main element, its single membrane desalination rate ≥99.5%, the system desalination rate 96-98%, can effectively remove the suspended particles in the water, organic silica gel, organic matter, bacteria, viruses, pyrogen and other impurities. |
| Ultraviolet ray sterilization (UV) | When the bacteria were exposed to ultraviolet light with A wavelength of 2600°A, the bacteria absorbed the ultraviolet energy and were killed |
| Ozone sterilizer | Ozone is a very strong oxidant, ozone water has a rapid and efficient sterilization. The concentration of ozone in water is 0.1-0.2mg/L, which can kill all bacteria. The concentration of ozone is 0.3-2mg/L, which can kill bacteria within 1 minute. |
