Sand Filtration of Oxidation Pond Effluent for Reuse in Park Irrigation

摘要

This study is an investigation of intermittent sand filtration of oxidation pond effluent utilizing local river bed sands as filter media. The experimental set-up for this investigation consisted of several laboratory scale filter columns filled with local river bed sands. These columns were dosed at a selected rate and sequence with oxidation pond effluent. The parameters investigated included depth, dosing sequence, and hydraulic loading rate. The results of the quality parameters investigated, including COD, volatile and total suspended solids, turbidity and algae concentration, were evaluated statistically.
