Industrial EDI reverse osmosis water purification treatment equipment mainly adopts four methods to prepare? Author of the article: Now, EDI reverse osmosis water treatment technology in industrial water treatment equipment more widely used, the better the technology, there are four methods to take: ion exchange, electrodialysis, distillation and reverse osmosis. These four technologies have their own advantages and characteristics. In the process of use, the corresponding preparation methods can be selected according to the required funding capacity, the difference in water quality and the size of the space. The ion exchange technology system is a skill that occupies a small area and invests less money. It is suitable for small companies to use, but it has a large demand during use and is harmful to the environment; industrial EDI reverse osmosis water purification equipment requires membrane elements Regular cleaning is used for companies that have slightly lower requirements for pure water quality; industrial EDI reverse osmosis water purification equipment is now a more useful and excellent pure water production equipment, and the water purity is improved through the method of electro-deionization. , Will not cause any impact on the environment, and the water purity of the produced water is higher, but the equipment investment cost is slightly higher than the other two. Nowadays, many industries usually choose industrial EDI reverse osmosis water purification equipment, which is a brand-new ultra-pure water production technology. The equipment operates stably and can be continuously produced. Industrial EDI reverse osmosis water purification equipment belongs to an energy-saving and environmentally friendly technology, which reduces waste water output and reduces environmental pollution, which brings great convenience to electroplating professional production. Purified water is a colorless, odorless, transparent liquid, which is widely used in pharmaceuticals, cosmetics, drinking water, swimming pools and other occasions. These all depend on the method used in the production of purified water equipment. Today, the environmental protection editor will help you analyze which four methods are used to prepare industrial EDI reverse osmosis industrial EDI reverse osmosis water purification equipment: 1. Ion exchange method: this The method uses anion and cation resins to exchange ions in water to obtain purified water. This method can be divided into mixed bed and multiple bed methods. The mixed bed ion exchange method has better deionization effect, but is not conducive to regeneration. The multiple bed ion exchange is used more in the early stage, and it is beneficial to the regeneration of the resin. 2. Distillation method: The raw water is heated to evaporate, then condensed to remove ions in the water. This method consumes a lot of energy. It has been used in pharmaceutical factories in the past, but it is not suitable for modern industry. 3. Reverse osmosis method: Using external pressure as the driving force, water molecules in the raw water are selectively permeated through the membrane to achieve the effect of desalination. This method is currently a widely used desalination technology. 4. Electrodialysis: under the action of a direct current electric field, the raw water uses anion and cation exchange membranes to selectively allow anion and cation to pass through, so that part of the ions migrate through the anion and cation exchange membrane to another part of the water, and finally a part It is purified and the other part is concentrated.
