Disinfection of treated sewage. [Ultra-violet irradiation]

Journal Article:

Abstract

The release of treated sewage in the vicinity of bathing places, drinking water sources or fish and shellfish culture plants is undesirable due to high bacterial content. Disinfection by chlorine would be relatively expensive and the toxicity would result in a local dead zone. The formation of small, but measurable, amounts of persistent chlorated hydrocarbons could also lead to long-term biological effects. Disinfection by ozone or gamma radiation would involve investments unacceptable in small plants. Ultraviolet radiation with wavelength 2500-2600 A has a powerful bacteriocidal effect and has been demonstrated to give bacterial mortality of 99.96 to 99.997 %. A standard plant produced in USA with a capacity of 11.3 m/sup 3//h is illustrated. UV radiation has no effect on the chemical composition of the water and the operating costs are low.
