Abstract

The aim of this study is to evaluate the disinfection effect of anolyte water on some species of bacteria detected in sewage sludge, by using different concentrations of anolyte water and different incubation periods. The results showed that tested bacterial species showed different reduction in their numbers by increasing incubation periods. Also, the obtained results showed that anolyte water in concentration of 1 ml produced 100% inactivation for E. coli, Staphylococcus sp., Bacillus sp., and Enterococcus sp < /em>. after 30min exposure time. While, 2ml anolyte water produced complete inactivation for E. coli, Staphylococcus sp., Bacillus sp.  and Enterococcus sp < /em>. after 20 min exposure time. In conclusion anolyte water can be used safely for inactivation of some pathogens found in sewage sludge.
