Effect of Media Properties on Performance of Sand Filtration for Drain Water Treatment

Abstract
Open drains in Egypt are currently suffering from increased pollution loads caused by discharge of untreated domestic and industrial wastewater. Untreated effluents adversely affect agriculture drains water quality and limit their potential for reuse. Belbies drain, which originates North of Cairo, is considered one of the most polluted agriculture drains in Egypt.
The research focuses on the efficiency of the sand filtration unit mixed with different media in drain water treatment, in which the analysis of variable parameters will be conducted, to optimize the design of the unit & investigate the most efficient configuration for the filtration unit to be operated with. Three media have been tested with the sand filter which are: perforated Ceramic cylinders, Sponge and 2 commercial activated carbon (Jacobi and A.C-LN).
The experiments were conducted in six experimental runs. The first run was conducted to determine the optimum depth of filtration for each type of filtration medium. It was observed that the best removal results have been obtained at filtration media depth of 120 cm. Also, sand mixed with other media such as Sponge and Activated Carbon has the better result than that of sand alone at depth 120cm with respect to total chemical oxygen demand removal, total suspended solids removal which were 75%, 58% respectively.
The second run of the experiment was conducted to study the performance of three filtration medium. It was noticed that the Activated carbon (Jacobi) has the best removal efficiency with respect to COD tot, T.S.S which were 79%, 94% respectively. The Sand medium mixed with Sponge had nearly the same results as sand mixed with A.C-LN.
The third run was conducted to study the effect of mixing ratio of Activated carbon Jacobi mixing with sand on the performance of the filter. It was noticed that, the removal efficiencies were increased as the weight of Activated carbon Jacobi in the mixing ratio were increased as well with respect to COD tot, T.S.S which were 88%, 99% respectively.
