EDI ultra pure water and RO reverse osmosis equipment are both used for industrial pure water production equipment, but there are still certain differences between these two devices. Many people are not very clear about the differences between these two devices and do not know which one is more suitable when choosing.
EDI ultra pure water is generally referred to as EDI, which mainly uses the purification technology of electronic deionized water and a new desalination process combining electrodialysis and ion exchange.
RO reverse osmosis equipment adopts advanced single-stage low-pressure reverse osmosis technology, and its technical principle is to purify raw water (tap water, groundwater) through membrane separation filtration powered by pressure gauge difference.
The advantages of EDI devices include:
1. During the operation of the equipment, no chemicals will be added, so there will be no secondary pollution caused by acid-base regeneration;
2. During the water production period, there are no complex operating procedures, allowing for continuous and stable water production without downtime due to regeneration;
3. The size of the entire device can be customized according to factors such as the height of the site, thus reducing installation requirements, occupying a small area, and reducing operating costs;
4. The entire water production process does not require human management, and no chemical agents need to be added during operation. The area occupied is small, so the overall operating cost is very low.
Advantages of RO reverse osmosis equipment:
1. Physical methods can be used for desalination;
2. Realize continuous water production and stable water output;
3. Reverse osmosis water treatment technology will not cause secondary pollution of water;
4. Wide range of applicable water quality;
Whether in the electronic industry such as cathode ray tubes, glass shells, integrated circuit blocks, monocrystalline silicon semiconductors, pharmaceutical industry water, desalinated pure water, thermal power boilers, deionized water for electroplating processes, pure water for battery production processes, etc., the above two types of pure water production equipment can be used. The advantages between the two are roughly the same, and which one is more suitable depends on the enterprise's requirements for water quality.
