Industrial water purification equipment introduction principle

Industrial water purifier is used for industrial production of water purification device. Industrial water purifier can be used for: drinking water, bottled water, food industry water, semiconductor industry, fine chemical industry, optical industry water, electroplating water, pharmaceutical water, dialysis medical water, instead of various types of distilled water and ultrapure water supply. A complete water treatment system consists of three main parts: pretreatment system, fine treatment system and post-treatment system. Raw water through the PP cartridge (sand rod filter), activated carbon unit, water softener unit and other pretreatment systems, so that the suspended solids in the water (particulate matter), colloid, organic matter, hardness, microorganisms, and other impurities content is greatly reduced, in order to reduce the subsequent reverse osmosis, electrode desalination, and other fine treatment system to reduce the processing load, and to prolong its service life. PP filter element Material: polypropylene hot melt fiber filter element. Characteristics: 10μm filter holes can retain particulate matter in the water (such as sediment, rust often found in tap water), reduce turbidity, but can not filter out bacteria and ionic substances. Specification: 10 inch (250㎜) / 20 inch (500㎜). Activated carbon unit Activated carbon has a large specific surface area and is covered with micropores of very small pore size (10-30?), which has obvious adsorption and filtration effects on organic matter colloids, residual chlorine, iron ions, and so on. Desktop water purifiers, water purifiers and other commonly used 10-inch / 20-inch activated carbon cartridge. Large water purifier unit commonly used fiberglass / stainless steel material activated carbon filter tank. Water softener unit Large and medium-sized water systems often use automatic water softener to remove calcium and magnesium ions in the raw water. Automatic water softener by the sodium ion resin tank, regeneration salt tank and multi-channel control valve, can set the program control operation, automatic regeneration (time type / flow type of two control modes), regeneration of the use of the siphon principle of salt suction, and then injected into the salt, regeneration time is usually 2 hours. Small desktop water purifiers generally use 10-inch / 20-inch water softener resin cartridge to reduce the hardness of the raw water. Reverse osmosis unit RO (Reverse Osmosis) reverse osmosis technology is the use of pressure gauge difference as the driving force of the membrane separation and filtration technology, originated in the United States in the 1960s astronautics research, and then gradually transformed into civilian use, has been widely used in scientific research, pharmaceuticals, food, beverages, seawater desalination and other fields. RO reverse osmosis membrane pore size is as small as nanometer (1 nm = 10-9 meters), under certain pressure, H2O molecules can pass through the RO membrane, while the inorganic salts in the source water, heavy metal ions, organics, colloids, bacteria, viruses, and other impurities can not pass through the RO membrane, so that can pass through the pure water and can not pass through the concentration of the water is strictly differentiated. RO membrane for high-value ions, colloids, bacteria and molecular weight greater than 300 dalton of organic substances (including heat source) removal rate of up to 99% or more, the removal rate of low-value ions (NA +, K +) up to 95%, when the source water conductivity & lt; 3505µs/cm, RO pure water conductivity is usually ≤ 55µs/cm. It meets the national standard of third grade water. And then through the atomic ion exchange column cycle filtration, the water rate of up to 18.2MΩ.cm. Reverse osmosis is the most economical way to achieve 90% to 99% impurity removal rate, but also reagent-level ultrapure water system is the best pre-treatment method. Note: The filtration capacity of RO membrane is greatly affected by the water temperature, the most suitable water temperature is 25℃～30℃, the temperature drops by 1℃, the water yield of RO membrane drops by about 3%, when the water temperature is close to 0℃, RO membrane will stop producing water. Ultrafilter unit Ultrafiltration membrane is also known as hollow fiber ultrafiltration membrane. The pore size is between reverse osmosis and microfiltration, about 0.01 ~ 0.1μm, commonly used as a post-treatment device for pure water systems, which can be used to retain a variety of particles in the solution, macromolecule solutes, bacteria, viruses, pyrogens and so on. The pore size of ultrafiltration membrane is determined by the retention test of certain molecular weight substances, and is expressed by the value of molecular weight. The molecular weight of ultrafiltration membrane that can filter out pyrogens is usually 6,000 daltons (dalton). Ultraviolet Instrument Unit Ultraviolet light is a kind of invisible light wave, exists in the outer part of the ultraviolet end of the spectrum, so it is called ultraviolet light, according to different wavelength ranges, it is divided into A, B and C bands, among which C band ultraviolet light wavelength is between 240 - 260nm, which is the most effective bactericidal wavelength, and the strongest point of the wavelength in the band is 253.7nm. When sufficient dosage is generated by the ultraviolet equipment, it can be used for the sterilization of the bacteria, and it can also be used for the sterilization of the bacteria. When the ultraviolet equipment produced by a sufficient dose of strong ultraviolet light irradiation to water, liquid or air, which a variety of bacteria, viruses, microorganisms, parasites or other pathogens in the ultraviolet UV-C radiation, cell tissue in the DNA, RNA is destroyed, thus preventing the regeneration of sub-cells, ultraviolet disinfection equipment in the absence of any chemicals, a shorter time (usually 0.2-5 seconds) kills the water, liquid, water and other pathogens in the water, liquid and air. UV disinfection equipment, without the use of any chemicals, in a short period of time (usually 0.2-5 seconds) kills more than 99.9% of bacteria and viruses in water, liquid or air. Scientific tests have proved that the wavelength of 240-280nm ultraviolet light has a highly efficient sterilization function. Modern ultraviolet disinfection technology is based on modern epidemiology, optics, biology and physical chemistry, based on the use of specially designed high-efficiency, high-intensity and long-life C-band ultraviolet light generating device, produced by a strong ultraviolet C irradiation of flowing water (air or solid surface), when the water (air or solid surface) in a variety of bacteria, viruses, parasites, algae, and other pathogens by a certain dose of UV C light radiation, the cells in the water (air or solid surface), the bacteria, viruses and other pathogens in the water (air or solid surface). When various bacteria, viruses, parasites, algae and other pathogens in the water (air or solid surface) are exposed to a certain dose of ultraviolet C radiation, the DNA structure of their cells is damaged, thus killing bacteria, viruses and other pathogens in the water without the use of any chemical drugs to achieve the purpose of disinfection and purification. Ultraviolet sterilizer with 304 or 316L stainless steel as the main material, high-purity quartz tube as a casing, with high-performance quartz ultraviolet low-pressure mercury disinfection lamps, has a strong bactericidal force, long service life, stable and reliable, etc., and its sterilization efficiency of ≥ 99%, the service life of imported lamps ≥ 9000 hours. Ultraviolet sterilization Ultraviolet light is a kind of invisible light wave, exists in the ultraviolet end of the spectrum on the outside, so it is called ultraviolet, according to the different wavelength range, is divided into A, B, C three kinds of bands, of which the C band of ultraviolet wavelengths in the 240 - 260nm between the most effective sterilization bands, the strongest point of the wavelength of the band is 253.7nm. The principle of ultraviolet sterilization is generally believed to be the nucleic acids in the organism absorb the energy of ultraviolet light and change their own structure, which in turn breaks the function of nucleic acids. When the energy absorbed by the nucleic acid reaches the lethal amount and the irradiation of ultraviolet light can be maintained for a certain period of time, the bacteria will die in large numbers. Characteristics of ultraviolet sterilization: 1. Ultraviolet sterilization is fast, efficient and effective. 2. 2. ultraviolet irradiation will not change the physical and chemical properties of water, pure water will not be brought into the pollution caused by additives. 3. Apply to a variety of water under the flow, simple operation, easy to apply, only need to regularly clean the quartz glass casing, replace the lamp can be. 4. small size, lightweight, low power consumption. 5. Ultraviolet sterilization has no continuous disinfection effect and is susceptible to secondary pollution. The oxidizing effect of ultraviolet (UV) light. Purification column unit purification column filled with the United States of America Rohm and Haas / Dow produced UP nuclear level mixed-bed resin, when the raw water through the purification column, the cations in the water and the cation resin in the H + replacement, the anions in the water and the anion resin in the OH - ion replacement, the exchange of water into the water of the H + and OH - will be immediately combined with the generation of H2O, so that the anions and cations in the raw water to be removed, and the resistivity of its water can reach a maximum of 18.3 MΩ.cm.
