<p>A filter apparatus 1 comprises an inlet 2 for receiving a target fluid to be filtered, an outlet 3 for allowing exit of filtered target fluid and a filter means 4 such as a plate disposed between the inlet and the outlet. The filter means has a lengthwise direction and a widthwise direction and the inlet is disposed proximal one portion of the filter means for delivering at least some fluid, such as water, onto the filter means initially in a lengthwise direction. The outlet is disposed on an opposing portion of the filter means in the lengthwise direction and is at a distance just below the inlet. A flushing arrangement (10, Fig 3;101, Fig 6) may be provided to remove debris from the filter means during a flushing operation. The filter apparatus maintains a low profile in a heightwise direction and may used in underground installations where a satisfactory drop is required between an inlet and an outlet, and also between an inlet and an overflow outlet which permits exit of excess un-filtered water and debris.</p> |
