1T/H ss304 Two-stage Reverse Osmosis System Plus EDI Module And PH Dosing System
EDI Module compare to Mixing bed
| Item | EDI | Mixing bed |
| Water production | 15～18MΩ·cm | 2～10MΩ·cm |
| Stability | Stable water quality | Water quality is affected by resin exchange and regeneration quality |
| Operational | Easy to operate, no need for skilled workers | High level of operator requirements during regeneration |
| Environmental protection | No acid or alkali, no chemical pollution | Need acid-base regeneration, need to solve the problem of acid-base storage and emissions |
| Continue to operate | No need to stop during regeneration, regeneration while running | Need to stop regeneration when regenerating |
| Operating expenses | Low | High |
| Initial investment | High | Low |

Main Components of 1T Two-stage RO+EDI Machine
1, Original water pump
The raw water pump provides the raw water pressure for the raw water pretreatment system. If the raw water is under pressure, you can completely avoid this equipment. General requirements for raw water pressure >=0.3MPa
2, Original water tank
The original water tank has a simpler function and is used for storing raw water. This is afraid that the original water will not be available for a transfer (usually adding a float switch is more automated than the entire system).
3, Quartz sand filter
Quartz sand filter material is used to remove suspended solids, sediment, impurities, etc. of larger particles in raw water to reduce the turbidity of water. Moreover, organic substances, bacteria, viruses, etc. in the water can be largely removed as the turbidity is lowered, and good conditions are created for post-filtration sterilization.
4, Activated carbon filter
The adsorption capacity of activated carbon is used to effectively adsorb organic matter, free residual chlorine, colloids, particles, microorganisms, certain metal ions and discoloration in raw water.
The reverse osmosis system is the core component of the entire pure water system, and only through reverse osmosis can the standard of pure water be achieved. The reverse osmosis system mainly uses a membrane filtration process. The water molecules can then pass through the reverse osmosis membrane. Others such as calcium, magnesium, and sodium ions are discharged along with the wastewater. The following components of the system.
1, Precision filter
The filter primarily filters large particle molecules in the water.
2, Special high pressure pump
Generally, the high pressure pump we use here is the southern special pump. Provides strong power for reverse osmosis equipment.
3, Two-stage reverse osmosis membrane
The reverse osmosis membrane uses membrane filtration technology. Let water molecules pass through other ions to achieve the purpose of purifying water.
4, EDI Module
It cleverly combines electrodialysis and ion exchange technology, using high-pressure electrodes at both ends to move charged ions in water, and mixing ion exchange resin and selective resin film to accelerate ion removal.
5, Auxiliary system
For example, ozone sterilization system, light inspection, filling system. It can also be sterilized by ultraviolet rays, and there is no residue of ultraviolet rays.
