  ABSTRACT: A declining rate filter operating through over flow control mode is proposed in this paper with a view to improving the overall performance of declining rate filters. Traditional declining rate filters have in-built self-adjustment of flow rates among the filters assisted with downstream orifice for flow control with limited flexibility for further adjustment. The proposed design allows the control of flow level and flow rates in individual filters, the water level in the over flow distributor tank and offers increased flexibility in responding to changes in filtration variables and optimising the overall performance of the filters. The design set up can also operate as constant rate filter through setting the water level in the distributor tank to the maximum.
