Disinfection with ultraviolet light (UV) is a widely recognized and proven method for treating industrial wastewater in industries like food and beverage, microelectronics and oil and gas. When microorganisms such as bacteria, viruses and protozoa are exposed to UV light, the UV energy destroys their genetic material. This process, known as thymine dimerization, eliminates the pathogens’ ability to reproduce and cause infection.  Disinfection is not the same as sterilization, but exposure to UV light is effective against E.coli, Crytosporidiym, Giardia and other types of pathogens. For disinfecting water, UV light in the UV-C or shortwave UV band is used. This band or category of UV light is a form of electromagnetic energy that is invisible to the human eye and has a lower wavelength than sunlight. UV light for water treatment is also used in total organic carbon (TOC) reduction and the destruction of chlorines, chloramines and ozone.  UV disinfection is a physical rather than a chemical process, so it will not alter the water’s chemistry or add color, odor or taste. It is environmentally friendly, has a small footprint and offers low operational and maintenance costs. When des...
