Abstract
The invention is directed to an automatic backwash filter system that includes at least one influent port for introducing a fluid to the filter; a plurality of partitions forming a plurality of compartments for holding a filtering media for filtering the fluid; at least one porous plate for supporting the plurality of partitions; wherein each of the partitions is mounted atop a continuous portion of the porous plate; and at least one effluent port for draining the fluid away from the compartments. The filter may also include a filter media comprising one or more selected from the group consisting of sand, anthracite coal, and activated carbon. The invention also includes a method for preparing the automatic backwash filtering system that includes the steps of arranging a plurality of partitions to form a plurality of compartments for holding a filtering media for filtering a fluid; binding together a plurality of porous plates by a lap joint at least one of the partitions; and securing the plurality of partitions to the plurality of porous plates so that each of the partitions is mounted atop a continuous portion of the porous plate to prevent the filtering media from passing therethough. Each of the plurality of partitions may be secured to the porous plate with angles and mounting bolts.
