Data for inactivation of free-living nematode Rhabditida from water environment using ultraviolet radiation

Sometimes free-living nematodes in conventional water treatment processes are not eliminated and cause adverse health effects in water consumer. So, the efficiency of UV lamps (125 W) with irradiation intensity 1020 [LW cm(-2). on inactivation of free-living nematode Rhabditida released in water samples has been investigated along with the investigation of the effects of turbidity and change of temperature and exposure time in constant of pH 8 +/- 0.2. The results showed that UV radiation could disabled the larval and adult nematodes after 12 and 15 min in the presence of turbidity 5 NTU, respectively. Also, increased turbidity up to 50 NTU decreased the inactivation efficiency of larval and adult nematodes from 100% to 73% and 64%, respectively. In addition, with increased temperature, the inactivation efficiency increased significantly in a short time. The results showed a significant relationship between increasing exposure time and temperature and turbidity reduction with UV radiation efficiency in the inactivation of the nematode (P < 0.00). It was also found that the efficiency of the lamp on nematode larvae was more than the adult nematode. Therefore, UV radiation can well inactivate larvae and then adult free-living nematode Rhabditida in water. (C) 2018 The Authors. Published by Elsevier Inc.
