    Abstract: The present invention is related to a method and system for cleaning a media support structure in a filter cell in a liquid filter system, wherein a cleaning solution does not significantly enter a filter media zone. The method comprises supplying a cleaning solution to a filter cell to a level sufficient to submerge the media support structure, but not to significantly enter the filter media zone. Additionally, the cleaning solution level is monitored to ensure the cleaning solution does not significantly enter the filter media zone. Alternatively, the cleaning solution may be continuously recirculated and reintroduced to the filter cell during the cleaning operation.

    Abstract: Porous media filters are commonly cleaned by backwashing. Immediately following the backwashing process, a high concentration of contaminant(s) pass through the filter, which is a phenomenon know as filter nullripeningnull or maturation in the municipal water treatment community. A new process has been invented that can reduce the concentration of contaminants that pass through a filter during nullripeningnull and is called the extended terminal subfluidization wash (ETSW). ETSW is a new backwashing process for porous media filters that involves using a washwater flow rate below the minimum fluidization velocity of at least some of the filter media grains following the primary cleaning stage of backwashing (e.g., fluidization) for an amount of time sufficient to displace the majority of the water volume in the filter during the overflow portion of the backwashing process.

    Abstract: The present invention is directed to a filter apparatus for filtering out suspended solids from liquid that is passed through filter material supported within a tank. The invention is also directed to a method of cleaning the filter material while the filter material remains inside the tank. The disclosed apparatus and method facilitates the removal of solids which are deposited on the filter material during the filtering operation, as well as biogrowth and other foreign matter. The cleaning method utilizes a suction generating device, such as a pump and associated suction heads, for backwashing the filter material. The cleaning method also utilizes a device for directing a liquid stream of a chemical cleaning solution at high velocity to the filter material thereby chemically washing the filter material and dislodging filtered solids and other foreign matter therefrom. The suction heads and the nozzle heads are positioned relative to the filter material such that substantially all of the runoff which results from operation of the liquid directing device is removed from the filter material by the suction heads.
