ABSTRACT
The inactivation efficiency of chlorine, ultraviolet light and ozone were determined for poliovirus type 3, Coxsackievirus type B4 and Hepatitis A virus in drinking water and treated effluent. Ultraviolet was more efficient than the other two disinfectants at wave length 254 rim where no infective virus was detected after 4 mm of UV irradiation in both drinking water and treated effluent. Inactivation by chlorine dose more than 25 mg/L was sufficient for studied viruses in both drinking water and treated effluent. Also virus- seeded drinking water was exposed to ozone for 18 min at ozone rate of 319 mg/L/h to obtain the maximum inactivation of PV3, CoxB4 and HAV but about 20 min of ozone exposure was needed for treated effluent. Physico-chemical parameters were measured before and after disinfection assay. No significant changes were observed
