| Abstract | ||
| Porcelanite rocks were selected to be the dual media with sand in this study to improve the performance of the filtration process in water treatment plants. The work required installing a pilot filtration unit in the location of the filters in one of the water treatment plants, so the experimental work was performed on the same influent water of the filters in the plant (the effluent from the sedimentation tank. The pilot filtration consists of three plastic column filters, working parallel and simultaneously. The first contains 70 cm sand (the same type used in the filters of the plant), the second and third were dual filters (porcelanite with sand) of different depths and sizes using different filtration rates (5, 10, and 15 m/hr). The results showed that the dual filters had better performance than sand filters in turbidity and bacterial removal, less initial head losses and less total head losses at different filtration rates. | ||
