EFFECT OF ANOLYTE WATER AS DISINFECTANT ON MICROORGANISMSIN SOME DIFERENT WATER SOURCESG.A. OSMAN AND A.A. MELEGYAbstract The main aim of this study is to evaluate the disinfection effect of anolyte water on microbes detected in different polluted sites. Samples were collected from outlet of Zenin Wastewater Plant, intake and finished water of El-Giza Drinking Water Treatment Plant, and ground water from eight wells in Rahawy Village region, Giza governorate, Egypt, during 2015. Results showed that, classical bacterial indicators were detected in Nile water and some wastewater samples, while they were absent from outlet of El-Giza Water Treatment Plant (except that total viable bacterial counts at 37°C and 22°C). Coliforms were detected in some samples of wells water (50% from all samples). Staphylococci group, Pseudomonas spp. total yeasts and total fungi were detected in ground water samples with averages 1.63, 2.83, 4.25 and 2.25 CFU / 100 mL, respectively. Total yeasts and total fungi were counted in outlet of El-Giza Water Treatment Plant as 20.88 and 9.88 CFU/100mL, respectively. All samples which collected from different sites, when treated with anolyte water (0.5 and 1% concentrations, v/v for 20 minutes contact time for drinking water and Nile water, respectively, as well as 5% concentration, v/v for 30 minutes contact time for wastewater) as a biocidal agent, all the previously mentioned microbes were not detected. Physico-chemical parameters [pH, total dissolved solids (TDS), manganese (Mn), and iron (Fe),] were estimated and appeared within permissible limits according to Egyptian Standard for drinking water and wastewater except Fe and Mn in groundwater samples. So, anolyte water can be considered as biocidal agent for inactivation of microbes in the aquatic environment.
