Abstract: A filter system for filtering water and/or wastewater which includes an underdrain system having a plurality of laterals that are anchored to the floor of a filter by a hold-down assembly. Preferably, the hold-down assembly does not rely on grout or other substance that is applied in a viscous or semi-viscous state and subsequently hardened as the primary means for connecting the underdrain laterals to the floor of the filter. Preferably, the hold-down assembly includes hold-down clips that can move relative to an anchor assembly and corresponding underdrain blocks so that the hold-down clips can cooperate with any desired portion of the corresponding underdrain blocks.

Abstract: A filter or clarification system for removing impurities from a liquid to be treated, i.e., influent. The system preferably includes a chamber for receiving a liquid to be treated. The chamber has a settling assembly including a plurality of inclined settling members forming a plurality of inclined liquid passageways through which the liquid to be treated is directed to remove impurities from the liquid to be treated. Preferably, the headloss of the settling assembly is solely controlled by one or more orifices formed in the settling members, i.e., the settling assembly is free of gaps formed between the settling members that appreciably affect the headloss of the settling system. Support members are provided for each of the settling members to allow the settling members to be easily and readily removed. Preferably, the support members provide sufficient stability to allow an individual to walk on the tops of the settling members. Preferably, the support members are configured to enhance clarification or filtration. It is also preferred that the support members and settling members be configured to permit the settling members to be readily and easily connected to the corresponding support member.

Abstract: A system and method for uniformly distributing fluids (e.g., washing and in-service) through a filter bed of a filter. The system and method of the present invention can be used with any type of filter that uses media to remove impurities from a fluid. The filter bed can include one or more layers of media. The media can be natural (e.g., sand, gravel, anthracite, etc.) or can be fabricated (e.g., plastic). The filter media can be supported by one or more layers of gravel. Alternatively, the filter media can be supported by a porous plate or other support designed to replace the gravel layers. The present invention includes a system having a distribution member configured to uniformly distribute a fluid through a filter bed of a filter. Preferably, the distribution member can be readily installed by relatively unskilled labor in both existing filters and new filters.

Abstract: A filter system for filtering water and/or wastewater including a sludge blanket clarifier for removing at least some impurities from influent. The sludge blanket clarifier includes a clarifier compartment in which a sludge blanket is to be formed to remove at least some impurities from influent directed into the clarifier compartment and through the sludge blanket. The clarifier compartment has at least one vertical sidewall extending from a bottom of the clarifier compartment to a top of the clarifier compartment. The clarifier compartment has a cross-sectional area that varies over at least a portion of a height of the clarifier compartment such that the velocity of influent just prior to entry into the sludge blanket is less than the velocity of influent just after entering the clarifier compartment. The sludge blanket clarifier preferably has one or more flocculator modules disposed in the clarifier compartment to aid in flocculation and distribution of influent. The sludge blanket clarifier preferably includes a sludge collection system for automatically removing excess sludge collected in the bottom of the clarifier compartment. The sludge blanket clarifier further includes a washing system for directing filtered or unfiltered water through the sludge collection system in a direction opposite to the direction of travel of sludge when being removed from the clarifier compartment to free any blockages or obstructions in the sludge collection system. Preferably, the sludge blanker clarifier is configured such that static head of the clarifier compartment can be used to backwash the influent distribution system to remove any blockages or obstructions in the influent distribution system. A recycle pump can be provided to seed the sludge blanket.

The system and method of the present invention can be used with any type of filter that uses media to remove impurities from a fluid. The filter bed can include one or more layers of media. The media can be natural (e.g., sand, gravel, anthracite, etc.) or can be fabricated (e.g., plastic). The filter media can be supported by one or more layers of gravel. Alternatively, the filter media can be supported by a porous plate or other support designed to replace the gravel layers. The present invention includes a system having a distribution member configured to uniformly distribute a fluid through a filter bed of a filter. Preferably, the distribution member can be readily installed by relatively unskilled labor in both existing filters and new filters. The distribution member is preferably configured to occupy only a small percentage of space in a portion of the filter system (e.g., a flume, a filter compartment or other suitable location of the filter system). In retrofit applications, the design of the distribution member is such that no significant alteration of the filter system or fluid velocity is necessary. Preferably, the distribution member includes one or more plates. The plate or plates are designed to create a uniform piezometric head at each portion of the underdrain regardless of how far a given portion of the underdrain is from the fluid inlet in the distribution chamber. A single plate can extend substantially the length of the distribution chamber. Alternatively, a single distribution plate may extend across only several portions of the underdrain (e.g., several underdrain laterals) leaving one or more portions of the underdrain (e.g., one or more laterals) unaffected by the distribution plate. Further, a plurality of plates can be arranged in a side-by-side fashion to extend substantially the length of the distribution chamber. Preferably, the design of the plate or plates allows them to be mass produced.

Abstract: An improved underdrain block for an underdrain system supporting a filter media bed in a liquid filtration system is provided. The underdrain blocks are preferably made of an extrudable polymeric material that is extruded in relatively long sections to provide light weight, strong, easily manufactured underdrain systems having a lower profile than prior art underdrain blocks. The underdrain block comprises an upper wall, side walls, a lower wall, at least one lateral member between the upper wall and the lower wall, at least two chambers within the underdrain block, each chamber being defined by the lateral member, a plurality of upper orifices in the upper wall of the underdrain block, and a plurality of internal orifices in the lateral member. The underdrain block is substantially greater in longitudinal length than a longitudinal distance between the upper orifices. In one embodiment, the underdrain block has rails situated on the upper wall for engaging extruded members, which in turn, have receiving recesses for receiving a layer of porous filter media. In another embodiment, the underdrain block further comprises an air nozzle for achieving an improved distribution of air through a filter bed during air backwashing.
