| Abstract | ||
| In this research, a bench-scale filter is designed and constructed in order to compare the performance of different media namely, sand, crushed marble stone and crushed red brick. The filters are operated under various operating conditions such as filter depth, raw water turbidity, pretreatment, effective size and uniformity coefficient. These filters are operated under conventional and direct filtration modes with different doses of alum. Statistical methods had been used to determine the best media using Duncan multiple range test. The result showed the superiority of crushed red brick media in the removal of turbidity and total bacteria. The results also indicated that filters operated under direct filtration mode show better performance than that operated under conventional filtration mode. The pH of treated water show slight increase for the two modes of filtration.Keywords: Filter media , Red brick, Marble stone, Sand filter. | ||
