Improvement of Oxidation Pond Effluent Quality by Sand Filtration
Keyword(s):
In this research, the sand filtration process is focused on as one of the techniques for raising the quality of oxidation pond effluent. Based on the data of down-flow filtration experiments, a mathematical model for DO and deposit is developed, and the behavior of the deposit in the sand filter is analyzed. The decomposition of the deposit follows a first-order reaction at a filtration rate higher than 5 m/day, while it follows a zero-order reaction at a rate lower than 1 m/day. From the relationship between deposit and head loss, the maximim quantity of the deposit is determined to be around 0.3 kg/m2 at the rate of 0.5-1 m/day and 0.2 kg/m2 at the rate of 5-10 m/day.
