Abstract
This study aimed to improve the Dyna-sand filter performance using dual coal sand media with different ratios to achieve the required efficiency. Two ratios of coal sand were applied in this study 4 sand to 1 coal and 2 sand to 1 coal to determine the best removal ratio for the Dyna sand filter unit, against different high solids loads (50 -150 ppm) and several rate of filtration (150- 250) m3/m2/d.
The study results showed that media with ratio (4 sand: 1 anthracite carbon), the Dyna-sand filter achieved turbidity removal ratio between (93 and 94%) with different rate of filtration and under different TSS loads. The increase of A.C. ratio achieved very smaller effect on removal efficiency between 1: 2% than the previous starting media ratio. This achievement with the coal increase is not economic effective when compared with the starting ratio.
The study concluded that; the application of dual media with ratio 4 S :1 A.C. is the best modification to Dyna sand filter.  The improvement in its turbidity removal ratio between 10: 20% compared with sand only against high inlet solids loads with different rates of filtration.
