Water equipment working principle and system structure Author: pure water equipment is a kind of water filtration equipment, water treatment flies, do not add any chemicals, direct civilian. The most important thing in pure water equipment is reverse osmosis technology. Its working principle is to apply a certain pressure to the water. The water passes through the reverse osmosis membrane. During the passage, the reverse osmosis membrane removes most of the inorganic salts (including heavy metals) in the water. ), organic matter, bacteria, viruses, etc. These impurities cannot pass through the reverse osmosis membrane. The principle is that the pore size on the reverse osmosis membrane is only 0.0001 microns, while the diameter of the virus is generally 0.02-0.4 microns, and the diameter of ordinary bacteria is 0.4- 1 micron. Pre-treatment As the pre-treated water will be purified by reverse osmosis one step further, it is necessary to remove impurities that affect the reverse osmosis membrane as much as possible; it mainly includes large particles, residual chlorine, and calcium ions and magnesium ions. In order to solve this problem well, precision filters, activated carbon adsorption filters and softening resins are designed to specifically remove large particulate matter, residual chlorine and calcium ions and magnesium ions in the water to achieve the best pretreatment effect. Reverse osmosis Reverse osmosis uses a high-pressure pump to provide a high-concentration solution with a pressure greater than the osmotic pressure difference. The water molecules will be forced to pass through the semi-permeable membrane to the low-concentration side. Reverse osmosis can filter out 90%-99% of inorganic substances. Most pollutants including ions, because of its outstanding purification efficiency, reverse osmosis is a very effective technology for water purification systems, because reverse osmosis can remove most of the pollutants. Ion exchange Ion exchange is the exchange of positive ions in the water with H+ ions in the ion exchange resin, and the negative ions in the water are exchanged with OH- ions on the ion exchange resin to achieve the purpose of purifying water. By removing ions through ion exchange, almost all ionic substances can be removed theoretically. At 25°C, the resistivity of the effluent reaches 18.2MΩ. cm. The quality of the water after ion exchange mainly depends on the quality of the ion exchange resin and the exchange efficiency of water and resin in the exchange column. The terminal treatment mainly produces ultra-pure water of ultra-low organic type, sterile type, and heat-free type according to the special requirements of customers. There are many treatment methods for different requirements, such as ultrafiltration filtration to remove heat sources, dual-wavelength ultraviolet oxidation to reduce total organic carbon (TOC) in water, and microfiltration to remove bacteria. Features of pure water equipment: 1. Large processing capacity, high water purification rate, ≥98% under normal conditions; 2. Strong removal of impurities and bacteria; 3. Low energy consumption; 4. Stable and reliable; 5. Equipment Small size, simple operation, easy maintenance, strong adaptability and long service life. Application range: Widely used in various places such as electronics factories, semiconductors, food, beverages, laboratories, chemicals, pharmaceutical factories and pure water stations.
