CenTROL® Filter Clusters Conventional Filtration

Each CenTROL Filter has four granular media filter cells positioned around a central distributor column.  Circular weirs evenly divide the water to each operating cell for filtration.  The water then flows down through the filter media and through the underdrain and out into an effluent chamber and over the effluent weirs.

During backwash, the effluent weirs provide backwash head to clean the filters with water from in-service cells.  Backwash waste is discharged from the bottom of the distribution column.

Prefabricated components include the distributor column, washtroughs, and underdrain forms.  These components simplify construction and minimize cost.
