摘要：Ultraviolet Radiation (UVR) has been accepted as an attractive alternative to chlorination for the disinfection of wastewater. In this study the effluent from Sahebgaranieh treatment plant was subjected to changes in UV transmission and turbidity in order to correlate these commonly measured parameters with the performance of a submerged -UV- reactor employed in disinfecting the effluent. Studies have shown successful performance of the reactor in disinfecting typical secondary effluents. Highly significant correlations are observed between TJV- transmission, turbidity, and the degree of coliforms inactivation which depend upon disinfection limit. Besides, the method was regarded suitable in disinfecting effluent samples, having suspended solids twice as much the discharge quality at disinfection detention time of 102 seconds. Average UV dosages ranged from 230 to 580 milliwatt - second per square centimeter.
