The goal is to produce water that is suitable for a specific purpose. Most water is purified for human consumption, but drinking water. In a study using UV-C to treat drinking water, A. niger was found to be completely inactivated after exposure J UV-C Sisti et al. 2017, which is in agreement with our study summary. We investigated the effect of ultraviolet germicidal irradiation UVI from a low-pressure mercury lamp on various pathogenic Aspergillus spp. including A. flavipes, A. flavus, A. fumigatus, A. glaucus, A. nidulans, A. niger, A. terreus, A. ustus and A. versicolor suspended in tap water under laboratory-scale conditions. The UVC band with prominent emission. of ultraviolet, UV radiation, on the other hand, can effectively inactivate various microorganisms in water and therefore its use is increasing.
