Wastewaters are one of the most important sources for transmission of pathogenic agents in environment, so they should be disinfected in a manner that their overall qualities become accordant with WHO-guidelines, if it is needed to reus water correctly. Unfortunately, the protozoa and parasitic worm's eggs can not be destroyed by chlorination alone. This experiment was carried out in order to determine the efficiency of the UV-Lamps in inactivation of the Ascaris Lumbericoides-ova which is the most resultant organism among the other nematode eggs. The minimum inhibitory dose of UVR (UVC plus UVB irradiances) for Ascaris-ova complete destruction ascertained to be 420 miliwatts-seconds per square centimeter.
