The authors distinguish industrial water equipment and laboratory water machine: With the rapid development of the real economy and the family business requirements for water quality, water equipment on the market is more and more used in the production of some experiments, treatment Large ones are used in industrial production, and some are used in family life. These equipments are generally divided into three types: one is pure water equipment for laboratory use, which can meet the water quality requirements of pure water and ultra-pure water in the laboratory; It is an industrial pure water equipment. The essential difference between pure water and laboratory pure water equipment is the amount of water to be treated. If it is large, it needs to be customized large-scale industrial pure water equipment; one is drinking-type pure water equipment, also called household pure water equipment. Water equipment. What is the difference between the two equipment? There will be some differences in the process flow. The following content will briefly introduce you: The working principle of industrial pure water equipment is to apply a certain pressure to the water to make the water molecules and Ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, and viruses dissolved in the water cannot pass through the reverse osmosis membrane, so that the pure water that has been permeated and cannot be permeated The concentrated water is strictly separated. According to different water quality requirements, the processes used are of different levels: Pretreatment: The traditional process consists of a mechanical filter, an activated carbon filter and a security filter. The newer process consists of mechanical filters, security filters and ultrafiltration. The second stage: reverse osmosis: it is composed of high-pressure pump and reverse osmosis, can be divided into one-stage reverse osmosis and two-stage reverse osmosis. Third stage: finishing: ion exchange and microporous filter, EDI and microporous filter The fourth level: EDI treatment: a continuous desalination process that organically combines electrodialysis and ion exchange. It is a high-tech green environmental protection technology. The fifth level: mixed bed treatment: mainly used to reduce the hardness, alkalinity and yin and yang in the water Ion, making it softened or deionized water. Laboratory pure water equipment adopts a combination of advanced reverse osmosis technology and ion exchange technology, using booster pumps, solenoid valves, high-capacity ion exchange resins, RO reverse osmosis membranes, filter elements, pipeline connections, control elements, and ultraviolet Products such as lights purify water. All levels of filter element function for laboratory pure water equipment: Level: Pretreatment: Use precision filters to remove large particles, residual chlorine, calcium ions, and magnesium ions in the water to achieve better pretreatment effects. The second stage: reverse osmosis: reverse osmosis is to use a high-pressure pump to provide a higher concentration of solution with a pressure greater than the osmotic pressure difference, water molecules will be forced to pass through the semi-permeable membrane to the side of the low concentration, and reverse osmosis can filter out 90%- 99% of the vast majority of pollutants, including inorganic ions. The third level: ion exchange: ion exchange is used to remove ions, theoretically almost all ionic substances can be removed. The fourth level: terminal treatment: mainly produce ultra-pure water of ultra-low organic type, sterile type, and heat-free type according to the special requirements of customers. What is the filtration process of the household water dispenser? The household pure water equipment is through five-stage filtration to reach the direct drinking standard, thoroughly filtering out bacteria (0.4-1 microns), viruses (0.4-0.02 microns), toxins, heavy metal ions, and organic Compounds and other harmful substances also increase the oxygen content of the water, making the water weakly alkaline, which is more suitable for human absorption, sweet and delicious. Filter element function at all levels of household pure water equipment: Grade: PP cotton: Initially filter the raw water to remove coarser particles, sludge, colloids, suspended substances, etc. in the water. The second level: granular activated carbon: adsorption of peculiar smell, color, organic matter, and some heavy metals in the water. Third level: carbon rod activated carbon: further removal of chlorine, organic compounds, color, peculiar smell, turbidity, etc. The fourth level: RO reverse osmosis membrane: 0.1 nanometer pore size, to remove bacteria, viruses, heavy metals, and other organic impurities in the water. The fifth level: post activated carbon: remove peculiar smell and improve taste.
