During the installation of the microwave and ultraviolet water treatment equipment, the commissioning shall be carried out continuously, production Silver ion sterilization A lot of work needs to be completed before installation. For example, some of their installations must meet the final installation standards and have the final acceptance standards, so that there can be more ways to deal with it, Silver ion sterilization programme The operation shall be carried out according to the relevant design requirements as far as possible, and all operations can be accepted during the operation process, so as to ensure the actual use.
Ultraviolet is a kind of light wave invisible to the naked eye, which exists outside the ultraviolet end of the spectrum, so it is called ultraviolet. Ultraviolet radiation is one of the electromagnetic waves from the sun, which is usually divided into four categories according to the wavelength. The following is a special form of material operation, which is a particle stream with disconnected particles. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. production Silver ion sterilization When ultraviolet rays irradiate microorganisms, energy transfer and accumulation will occur, and the accumulation results in the inactivation of microorganisms, thus achieving the purpose of disinfection. When bacteria and viruses absorb more than 3600~65000uW/cm2, it has a strong destructive power to DNA and RNA of bacteria and viruses, Silver ion sterilization programme It can make bacteria and viruses lose their viability and fecundity, and then eliminate bacteria and viruses to achieve disinfection and sterilization effect. On the one hand, ultraviolet light can mutate nucleic acids, hinder their replication, transcriptional blockade and protein synthesis; On the other hand, the production of free radicals can cause photoionization, which will lead to cell death.
Stainless steel wire woven filter screen is often used, 30-40 hole/cm filter screen is used for crude oil filtration, and 140-180 hole/cm filter screen is used for decolorization oil filtration. production Silver ion sterilization The selection of filter medium will affect the clarification of filtered oil and fat, and whether the cake unloading is smooth. The filter media used in the grease industry are mostly woven media, Silver ion sterilization programme Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.
1. If linear installation is required, please use the installation method of low water inlet and high water outlet to slow down the water flow rate and increase the effect of ultraviolet radiation. 2. When working, Silver ion sterilization programme Do not look directly into your eyes with an ultraviolet lamp. When the equipment is open, repeated opening and closing will seriously affect the service life of the lamp. 3. If the water flow is too fast, please install current limiting and pressure limiting devices. 4. If the turbidity of raw water exceeds 5 degrees, a prefilter should be installed to ensure ultraviolet sterilization. 5. Please take out the quartz sleeve every time. production Silver ion sterilization After using the disinfection lamp for two to three months, check the surface for dirt to determine the next time to clean the surface of the quartz sleeve.
Ultraviolet disinfection can ensure sterilization effect and water quality. This is a long-term effective sterilization technology. There is no reactivation reaction and no rebound of flora, ensuring complete disinfection effect and water quality safety. production Silver ion sterilization Compared with other sterilization methods, UV has many obvious advantages, especially the difference from chemical disinfectants is that UV sterilizers will not bring toxic substances and residues into pure water, and will not change its chemical composition, odor and pH value. This function is very important in the pharmaceutical industry and related industries. Silver ion sterilization programme The chemical dosage of influent often changes the characteristics of the product. It can effectively kill all bacteria and viruses, and inactivate chlorine resistant microorganisms such as Legionella, Escherichia coli and Pseudomonas. Cryptosporidium, amoeba and bacteria.
The simple answer is yes, even more organisms. The research shows that 254nm ultraviolet light is effective for all food borne pathogens, natural microbiota, mold and yeast. Silver ion sterilization programme Because the size and shape of microorganisms will affect their absorption of ultraviolet light, the time required to kill each species is also different. How does UV sterilize? production Silver ion sterilization The working principle of ultraviolet sterilizer, also known as ultraviolet disinfection or ultraviolet germicidal radiation (UVGI), is to destroy some chemical bonds, disrupt the structure of DNA, RNA and protein, resulting in the inability of microorganisms to reproduce. When a microorganism cannot reproduce, it is considered dead because it cannot reproduce in the host body and is no longer infectious.
