RO plant is raw water through precision filter, granular activated sand filters, activated carbon filters, compression, and then the pump pressure, the use of (ro) reverse osmosis membrane pore size 1/10000μm make a higher concentration of water into low concentration of water, while the industrial pollutants, heavy metals, bacteria, viruses and other impurities in the water mixed with a large number of full isolation, to achieve the required physical and chemical indicators for drinking and hygiene standards, outputs to clean pure water is the best choice of body replenish water quality. It is key equipment of pure water plant.
Two stage RO system
This water treatment system uses mechanical filters, activated carbon filter as a pre-class treatment, the effective removal of suspended solids in raw water, sediment particles , organic colloids, organic matter, odor, chlorine and other impurities, with pre-programmed as a reverse osmosis desalination plant to remove the raw water. Most of the dissolved salts, bacteria, hot stream and so on, to ensure finished water quality standards.
If raw water conductivity is less than 300uS/cm, first stage output is less than 10uS/cm, two stage output is 2uS/cm.
EDI system
EDI, also known as electric desalination. It is a new ultra pure water technology which gradually developed in the 20th century. EDI equipment combined electro dialysis technology and ion exchange technology. It is using the selectivity penetrate function of anion and cation membrane and exchange function of ion exchange resin, under direct current electric field to make ion directed migration. Finally to make deep desalination of water. In the same time, hydrogen ion and hydroxide ion which produced when water ionize will regenerate ion exchange resin. So if use EDI equipment, no need acid and alkali chemical to do any regeneration, and it can produce ultra pure water continuously.
Advantages of EDI Technology
| 1.Best stability of water quality |
| 2.Constantly produce ultrapure water as per user requirements |
| 3.Modular production, can achieve automatic control |
| 4.No need acid and alkali regeneration, no pollution emissions |
| 5.No need stop because of regeneration |
| 6.No need regeneration equipment and chemical storage |
| 7.Compact equipment, small size |
| 8.Low operation and maintenance cost |
| 9.Simple operation and low labor strength |
