Abstract

Reuse of refined sewage with two goals of providing more water and protecting the environment from pollution is one of the solutions to water supply problems and one of the potential sources for irrigation in agriculture. The aim of this study is to evaluate the possibility of effluent disinfection using a sand filtration system to reduce microbial contamination with potassium permanganate powder. Each experiment was performed in 3 replications. The results of this study showed that adding 5 weight percent of potassium permanganate powder to silica sand eliminates the removal efficiency of total coliform and focal coliform to 99.99%. By reducing this percentage to 0.15 weight percent of potassium permanganate powder as the optimal amount, the results were the same. Also, the addition of 15 weight percent of potassium permanganate powder with silica sand increased the amount of opacity removal and the removal efficiency was 95.5%. As measured parameters were less than environmental standards. According to the results, the performance of potassium permanganate powder with silica sand is better than other treatments.
