Of the physical methods of destruction of harmful micro-organisms most widely used disinfection with ultraviolet rays by means of decontaminating the quartz, which is also called kvartsevatel. Disinfecting effect of ultraviolet radiation, mainly due to photochemical reactions that occur due to the UV lamps, resulting in irreversible damage to DNA, RNA and cell membranes, causing the death of microorganisms. Germicidal rays destroy not only the vegetative forms of bacteria, and spore-forming. To date, widely used for UV emitters home use. The main element of this device is a transmitter unit consisting of waterproof housing, a semiconductor emitter and a protective cap. Contact with the UV light occurs through bottom hole cap.

The housing is made of plastic in the form of a float cap of stainless steel protects against unwanted UV rays hitting the eyes. The advantages of UV disinfection of water include: reducing the time of disinfection, compact, unchanging taste and chemical properties of water, ease of manufacturing equipment, improve the environmental purity of the process, as well as significant cheapening of the process. Also note that the traditional water disinfection with chlorine will not get rid of pathogens. There are a number of aquatic pathogens resistant to chlorine: Pseudomonas aeruginosa, Adenoviruses, Enteroviruses, Hepatitis A, Entamoeba histolytica, Giardia intestinalis, Cryptosporidium parvum, Dracunculus medinensis fight that will only kvartsevatel water. The principle of UV-devices based on the hard ultraviolet UV emitter, which is in contact with microbial cells break down proteins and enzymes are colloids of protoplasm. Ultraviolet light is invisible light range to the human eye.
