| Abstract | ||||
| The traditional sand filter which used strictly in modern irrigation system as a gravity flow system requires at least 1.2 m hydraulic head. Designing and testing of a new proposed filter is the main objective of this study, besides comparing its performance with the performance of the traditional sand one. the study conducted with two irrigation water levels different in quality which were Nile water and the mixed agricultural drainage water at two levels of water flow rate inside the filter (5 and 7 m3.h-1). The new proposed filter comprises separately three types of filtration media; one contains gravel layer of 13 cm thickness and mixed gravel and sand layer of 13 cm thick, the second media contains the same two layers besides a sand layer of 13 cm thick, while the third media contains another layer of mixed gravel and resin with 11 cm thick. The highest removal efficiency of 95.7% was recorded with the new proposed filter at 5 m3.h-1 of Nile water flow rate, with the filtration media that contains four layers (gravel, mixed gravel and sand, sand only and gravel mixed with resin). The lowest removal efficiency of 72.04% was recorded with 7 m3.h-1 of mixed agricultural drainage water flow rate with the traditional sand filter. The lowest pressure drop (3.75 kPa) was recorded with the new proposed filter after 900 h of operating times at 5 m3.h-1 of Nile water flow rate. | ||||
