The application of UV technology in wastewater treatment

Sterilization

UV sterilization is by use of 254 nm wavelength UV light. Wavelength ultraviolet light, even in a small amount of ultraviolet light projected dose, can also destroy the life of a cell core - DNA, thus preventing cell regeneration, and loss of regenerative ability of the bacteria harmless, so as to achieve the effect of sterilization. Like all other UV applications, the scale of such a system depends on the intensity of ultraviolet radiation (irradiation intensity and power) and contact time (water, liquid, or air exposure to ultraviolet light, the length of time).

Reduce the total organic carbon

Among many high-tech and laboratory devices, organic matter will prevent the production of high purity water. There are many ways to the organic matter removed from the water, the more commonly used methods include the use of activated carbon and reverse osmosis. Shorter wavelength ultraviolet (185 nm) can also effectively reduce the total organic carbon (the value of mentioning these emitter of 254 nm wavelength ultraviolet light, can be disinfected). The shorter wavelengths of ultraviolet light has more energy, so the decomposition of organic matter. UV oxidation of organic reaction process is very complex, its main principle is a strong oxidizing ability of free hydroxide, oxidation of organic matter into water and carbon dioxide. And ozone removal system, this degradation of organic carbon, UV ultraviolet radiation dose is three to four times that of the conventional disinfection systems.

Liquid sugar disinfection

Most of the food and beverage manufacturers use liquid sugar. Sugar is the food that is easy to use bacteria, making it easy to promote bacterial growth. In addition, the liquid sugar is opaque, it is difficult to carry out thorough disinfection. 254 nm wavelength ultraviolet rays can be used for disinfection of liquid sugar products. To compensate for the liquid viscosity and color of the energy loss caused by ultraviolet transmitter needs to be tightly lined up to form the so-called "thin film" reactor. The close combination of this radiation can provide the required very high amount of ultraviolet radiation, which allows for effective disinfection of liquid sugar. Its ultraviolet energy output is approximately 7-10 times that of traditional disinfection system.

Degradation of residual chlorine

In municipal water treatment and water systems, chlorination is necessary. However, in the industrial production process, in order to avoid the adverse effects of the product to remove the residual chlorine is often necessary pre-treatment. The basic way to eliminate chlorine activated carbon bed, and chemical treatment. The disadvantage of activated carbon treatment is that it needs to continue to regenerate, but often encounter the problem of bacteria. 185 nm and 254 nm wavelengths of ultraviolet light have been shown to effectively destroy the chemical bonds of chlorine and chloramines. Although the need for tremendous UV energy can play a role, but it has the advantage of this method, no water to add any drugs, do not need to store chemicals, easy to maintain, but at the same time there are sterilization and removal of the role of organic matter.

Surface and air disinfection

With ultraviolet air disinfection and ultraviolet light for water disinfection as a long history. Air disinfection equipment used in hospitals, clinics and purify the room for years. Now, factories, offices and homes have begun to use the air disinfection equipment.

The principle of air disinfection and water disinfection. Typically, ultraviolet light can be installed in air ducts, located in the front end of the coil, or mounted on a wall shelf. When air passes through the airborne microorganisms were killed and rendered harmless. The principle of surface disinfection as well. In the food and beverage manufacturing industry products on the conveyor belt is carried by surface disinfection equipment disinfection.
