摘要： Devices and methods associated with these devices for significantly reducing or eliminating liquid (e.g., water) in a water or wastewater treatment unit above the underdrain from moving downwardly into the underdrain during an air only wash cycle of the treatment unit. The treatment unit can take many forms including but not limited to an upflow filter and a downflow filter. The treatment unit may include a filter bed having one or more layers of filter media supported by gravel above the underdrain. The treatment unit may also include an underdrain having a porous plate, slotted plate or slotted upper structure that obviates the need for gravel. Positive pressure is provided to the underdrain to overcome the downward force of the driving head in the treatment unit to significantly reduce or prevent liquid present in the treatment unit above the underdrain from moving downwardly into the underdrain.

摘要： Systems for use in one or more sludge or waste collection devices (e.g., containers, vessels or basins). One such system is a sludge removal system for removing sludge from one or more sludge collection devices. The sludge removal system includes one or more sludge removal grids disposed in one or more sludge collection devices. Each sludge removal grid preferably includes at least one header and a plurality of sludge collection laterals. Another such system includes a fluid distribution system for distributing one or more fluids in one or more sludge or waste collection devices. A movement restricting or prevention member is provided in both the fluid distribution and sludge removal systems to prevent or restrict movement of the sludge collection laterals and the fluid distribution laterals away from or towards a floor of a corresponding collection device without anchoring or fixing the laterals to the floor.

摘要： An apparatus for use in a filter system for filtering water or wastewater. The apparatus preferably includes at least one underdrain lateral having at least an inner chamber, a first outer chamber and a second outer chamber. The first outer chamber and the second outer chamber are preferably in fluid communication with the inner chamber. The inner chamber, the first outer chamber and the second outer chamber are preferably formed by an inner liner and an outer liner. The outer liner is a separate piece from the inner liner and surrounds the inner liner. The inner chamber is preferably configured to simultaneously receive a liquid and a gas during a washing procedure including simultaneous use of a liquid and gas to clean a filter bed to create a liquid and gas interface in the inner chamber.

摘要： An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.
