Devices and methods associated with these devices for significantly improving the efficiency of an existing or new filter having a granular media filter bed. The methods and devices are designed to increase the height and hence overall volume of the filter bed to allow for longer filtration runs between washing or cleaning cycles of the granular media filter bed. One embodiment includes a multi-wash trough adapter that upon removal of an existing deep wash trough connects two shallow wash troughs or two shallow wash trough channels to an existing wash trough opening formed in a wall of a filter compartment. The shallow members have a height significantly less than the height of the existing deep wash trough, e.g., one third to one half of the height of the existing deep wash trough allowing the volume of the granular media filter bed to be significantly increased.
A method of retrofitting an existing treatment unit having a granular media bed for removing impurities from a liquid and one or more wash troughs disposed above the granular media bed, said method comprising the step of:
A multi-wash trough adapter, said multi-wash trough adapter including:
A method of retrofitting an existing treatment unit with an existing granular media bed having a first volume of filter media for removing impurities from a liquid and one or more existing deep wash troughs disposed above the existing granular media bed wherein during retrofitting at least one of the one or more existing deep wash troughs are replaced with two new shallow wash trough channels and granular media is added to the existing granular media bed to increase the first volume of filter media to a second volume of filter media greater than the first volume of filter media to improve filter efficiency, said method comprising the step of:
