  The medium pressure uv sterilizer uses the irradiation intensity of the ultraviolet lamp, that is, the irradiation intensity of the sterilization lamp, which is inversely proportional to the distance of the disinfection object. When the radiation intensity is constant, the longer the sterilized items stay and the closer they are to the sterilization lamp, the better the sterilization effect, and vice versa, the device can be used in direct drinking water devices to achieve the purpose of purifying water quality. Its advantages include:

  1. Safe and reliable: Ultraviolet sterilization effect is extremely high, no chemicals are needed, and there is no secondary pollution to water bodies and the environment.

  2. No toxic and harmful by-products: UV irradiation does not change the properties of organic compounds, does not contain chemical reagents, does not produce harmful by-products, and does not increase by-products such as TOC.BOD that damage biological stability.

  3. The special disinfection effect of Cryptosporidium and Giardia, the traditional sterilization method has a very low killing effect on Cryptosporidium and Giardia. Under large doses, a large amount of disinfection by-products will be produced. By reducing the amount of radiation killing It has a good inactivation effect on the insect Cryptosporidium.

  4. It can reduce odor and degradation of organic matter. Ultraviolet light has a certain ability to degrade various trace organic compounds, and at the same time, it can reduce the odor and taste of water.

  5. Water temperature and pH have little effect on the disinfection effect.

  

  One of the treatment functions of the ozone generator is to dissolve the algal cells, and the other is to kill the algae, so that the dead algae can be easily removed by the subsequent process. Ozone generator can be used as a pretreatment method for algae removal. It is one of the effective ways to deal with algae problems in eutrophic water source water when used in conjunction with conventional treatment and other technologies. Algal toxins are becoming another focus of algal pollution. Under certain conditions, ozone generators can effectively remove some algal toxins. The specific removal rate mainly depends on the dosage of the ozone generator, followed by the raw water quality (algal toxin type, The nature and concentration of organic matter, alkalinity, etc.).
