①YY-softening functional filter element; Bloylite resin imported from the UK mainly reduces water hardness. Bloylite resin has a large exchange volume in water, which is 50% longer than domestic 001 * 7 cationic resin, which can extend the life of reverse osmosis and improve RO Desalination rate of water.
YY-UF ultrafiltration deep processing filter element; polypropylene (PP) hollow fiber membrane ultrafiltration membrane, mainly removing organic matter in source water can protect reverse osmosis and reduce TOC has a good effect.
Two-stage reverse osmosis purification system
RO (reverseosmosis) reverse osmosis technology is a membrane separation and filtration technology using pressure difference as the driving force. Originated from aerospace science and technology research in the United States in the 1960s. The RO reverse osmosis membrane has a pore size as small as nanometers (1 nanometer = 10-9 meters). Under a certain pressure, H20 molecules can pass through the RO membrane, while impurities such as inorganic salt ions, organic matter, colloids, bacteria, heat sources in the source water cannot Through the RO membrane, the pure water that is permeable and concentrated water that is impermeable are strictly separated;
RO membrane can remove 99% of high-valent ions, colloidal bacteria and organic matter (including heat source) with molecular weight greater than 300Dalton, and 90-95% of low-priced ions (NA, K0). When the source water conductivity is<350μs / cm. The conductivity of RO pure water is usually <= 5μs / cm. It meets the national standard for third-class water use. The reverse osmosis method is the most economical method to achieve 90-95% impurity removal rate. It is also the best for ultrapure water system. Pre-processing method.
Optional: post-treatment ultra-purification system
Ion-exchange resins use H + exchange to remove cations in the water and OH- to remove anions in the water. The H + and OH- replaced in the resin combine to form H2O. The ultra-purification column is packed with Dow UPW-450. Special polishing resin for ultrapure water, its water resistivity can reach 18.2MΩ.cm.
Rhenium ion exchange is a traditional, mature process desalination equipment. Due to the differences in equipment structure and technology, such equipment can produce desalinated water, pure water, high-purity water, and ultra-pure water. Widely used in various industries such as electronics, machinery, chemical industry, shipping, food and beverage and medicine. According to the user's source water quality and water standards, various types of beds can be combined in various ways to meet the user's water quality standards. The control system can be divided into automatic and manual. The principle of ion exchange is that under certain conditions, functions such as softening, alkali removal, and salt removal are achieved by relying on the exchange of certain ions of the ion exchanger (resin) itself with the isoelectric ions in the water to be treated.
