AbstractIn this research the filtration process in water treatment plants was studied to increase the filtration rates in the sand gravity rapid filters. A model was designed with dimensions (60*60*225) cm with sand media of two layers . Seven experiments were done in this research for each case of filter media thickness,( which are five cases ) . Using new method of operation , involves the suction of water from the drainage pipes network through the sand media . In this method, the filtration velocity was Doubled, with filtration efficiency nearly to (92%).
