Disinfection principle of medium voltage ultraviolet sterilization equipment:

The principle of medium pressure ultraviolet sterilizer and low-pressure ultraviolet sterilizer is basically the same. The main difference lies in the fact that the ultraviolet lamp used belongs to the medium voltage standard. The ultraviolet lamp contains a small amount (liquid or solid) and appears in a vapor state under light irradiation. When evaporated, the photoelectrons bombard and produce various wavelengths of ultraviolet light. The wavelength of the emitted ultraviolet light depends on the vacuum pressure inside the lamp. The low-pressure ultraviolet lamp is evacuated to a lower pressure (1-10 Pa) and can emit a single ultraviolet wavelength sterilization light of 254 nanometers. The medium pressure ultraviolet lamp is evacuated to a medium pressure (10-50 Pa) and can emit ultraviolet light with a wide spectrum of 230nm to 370nm. When ultraviolet light is irradiated on microorganisms, energy transfer and accumulation occur, resulting in the collapse of the microbial cell wall and killing microorganisms. When microorganisms absorb doses exceeding 3600-65000 uw/cm2, the accumulation of energy causes the microbial cell wall to collapse and kill microorganisms. It has strong destructive power against it, Microorganisms lose their ability to survive and reproduce, thus achieving the purpose of disinfection and sterilization. In summary, the principle of ultraviolet sterilization and disinfection is to use the irradiation intensity of the ultraviolet lamp tube, that is, the irradiation intensity emitted by the ultraviolet sterilization lamp is inversely proportional to the distance of the disinfected object being irradiated. The higher the irradiation intensity, the better the disinfection effect. When the irradiation intensity is constant, the longer the irradiation time of the disinfected object being irradiated and the closer it is to the sterilization lamp tube, the better the disinfection effect, and vice versa.

Application scope: Widely used in the pre-treatment of water quality in pure water, food and beverage water, mineral water, electronics, printing and dyeing, papermaking, and chemical industries, as well as the filtration of industrial wastewater after secondary treatment. It is also used for deep filtration in reclaimed water reuse systems and swimming pool circulating water treatment systems. It also has a good removal effect on suspended solids in industrial wastewater.

Working principle: Using the adsorption performance of activated carbon to remove impurities from the liquid and purify it. Capable of adsorbing metal ions such as silver, bismuth, hexavalent chromium, antimony, and tin ions. It can effectively remove color and odor, as well as industrial heat sources from water, extending the service life of the exchange resin. Softener: also known as ion exchanger, ion exchanger is used to reduce the hardness of water. Raw water is softened from top to bottom through the exchanger, and the magnesium, calcium, and cations contained in the water exchange with the sodium ions of the water exchanger, making it less likely for carbonate and sulfate scales to form in the water, thus obtaining softened water.
