A comparative study of the addition effect of activated carbon obtained from date stones on the biological filtration efficiency using sand dune bed.

Abstract : Up to now, even with the tremendous social and technological progress, pollution problems still occupy the focus of many researchers all over the world, and hence this paper focused on the treatment of domestic wastewater. In this context, a bi-layer filtration system made of sand dune and activated carbons have been developed. This latter was obtained from the hydrolysis of local date stones. The total thickness of the filter media was 60 cm. The height of the resulting bed ranged from 0 to 24 cm, and was controlled by adding only activated carbons. The efficiency of the filtration system was evaluated by monitoring the time-courses of COD and BOD5 values, as well as their evolution over the height of the bed. The comparison of these results to those obtained with a bed of sand dune only showed a clear enhancement of the efficiency which lay between 80-95 (%) for COD and 78-94 (%) for BOD5
