Abstract: A dissolved air flotation clarifier for removing impurities from a liquid to be clarified. The dissolved air flotation clarifier includes a housing having an inlet for receiving a liquid to be clarified. The housing further includes a reaction zone, a clarification zone and an effluent channel. The reaction zone has at least one saturated water distributor and at least one dissolved air flotation nozzle operably connected to the at least one saturated water distributor to receive saturated water from the at least one saturated water distributor. The dissolved air flotation nozzle is configured to release micro-bubbles from a saturated water so that the micro-bubbles can mix with the liquid to be clarified to remove impurities from the liquid to be clarified. The clarification zone includes a flow control member for controlling the flow of the mixture of micro-bubbles and liquid in the clarification zone to ensure that the area surrounding the inlet to the effluent channel has little or no micro-bubbles to prevent or significantly reduce micro-bubbles from becoming entrained in a clarified liquid passing through the effluent channel.

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.

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. The distribution member is preferably configured to occupy only a small percentage of space in a distribution chamber (e.g., a flume). In retrofit applications, the design of the distribution member is such that no significant alteration of the distribution chamber or fluid velocity is necessary. Preferably, the distribution member includes one or more plates extending substantially the length of the distribution chamber. The plate or plates are designed to create a uniform pizeometric head at each lateral extending from the distribution chamber regardless of how far a given lateral is from the fluid inlet in the distribution chamber. In a most preferred embodiment, a single plate is used. The design of the single plate allows it to be mass produced and yet still be used in numerous different environments and flow conditions.

Abstract: A filter system having a filter bed for filtering water or wastewater, where the filter bed is periodically washed between service runs by directing washing liquid and washing gas upwardly through the filter bed. The filter system includes a filter bed and at least one flume. The flume is in fluid communication with the filter bed. Preferably, the flume is configured such that no washing liquid and washing gas interface is present in the flume. The flume may be configured such that during washing of the filter bed between service runs the flume receives a washing gas and directs the washing gas upwardly through the filter bed to assist in cleaning the filter bed between service runs. The flume may further be configured such that during washing the only liquid directed from the flume to the filter bed is residual liquid that may be present in the flume from a prior service run.

Abstract: An apparatus for filtering water and/or wastewater including at least one underdrain lateral. The underdrain lateral is configured to receive a liquid during a filtration cycle and directs a washing fluid through a filter bed of one or more layers of filter media during a washing cycle. The filter can take any form including but not limited to an upflow clarifier, an upflow filter, a downflow clarifier, a downflow filter and a bi-flow filter. The filter media may be supported by one or more layers of gravel. Alternatively, a porous plate can be attached to the underdrain lateral in place of the gravel layers. The washing cycle can be a liquid only wash, a gas only wash, a combined liquid and gas wash or a combination of any of the aforementioned wash cycles. Preferably, the underdrain lateral includes a primary gas chamber and a secondary gas chamber where the secondary gas chamber serves to equalize pressure differences that may occur during the initial distribution due to velocity head changes and friction effects. Preferably, the underdrain lateral includes a plurality of chambers directing a washing fluid into the filter bed during a washing cycle where at least one of the plurality of chambers directs a liquid and a gas simultaneously into the filter bed and at least one other chamber of the plurality of chamber directs only one of a liquid and a gas into the filter bed at the same time as that the combination of liquid and gas is directed into the filter bed. Preferably, the height of evacuation openings formed in at least one wall common to a gas wash chamber and at least one adjacent chamber are varied to compensate for velocity head or friction loss.

Abstract: An underdrain system for a filter having filter media. The underdrain system preferably includes a bottom formed of concrete having a plurality of generally cone-shaped depressions formed therein. Fluid flows through the plurality of generally cone-shaped depressions during filtration and washing. The underdrain system further includes a fluid distributor operably associated with at least one of the generally cone-shaped depressions. The fluid distributor preferably has a plurality of elongated slots for distributing the flow of fluid passing into and out of the generally cone-shaped depressions. The slots are sized to prevent filter media supported by the fluid distributor from passing therethrough. An optional insert may be provided to ensure even distribution of fluid through the fluid distributor.
