Abstract: Methods and systems for filtration are disclosed. A feed mixture including at least one liquid component and at least one solid component and a flow of gas may be directed to a filter element and filtrate and gas may be passed through a filter medium from a feed fluid side to a filtrate side. The gas loosens and removes foulants accumulating within and on the upstream surface of the filter medium. The gas and filtrate may be separated from one another after passing through the filter medium.

Abstract: The disclosure relates to a filter apparatus together with a method for the filtration of liquids, such as, in particular, water, with a housing with an inlet and a filtrate outlet for filtered liquid, with a filter means which is arranged in the flow path of the liquid between the inlet and the filtrate outlet for filtering out particles from the liquid, and with a dirt discharge via which filtered-out particles can be discharged from the housing, the filtrate outlet being assigned an outlet valve and the dirt discharge being assigned a discharge valve. According to the disclosure, the outlet valve and the discharge valve are coupled in such a way that the discharge valve opens the dirt discharge only when the outlet valve has at least partially shut off the filtrate outlet, in order thereby to generate a cleaning pulse.

Abstract: An apparatus for the separation of a solid/liquid suspension by filtration includes a tank filled with a suspension to be treated. At least one cavitied plate is located in the tank and has at least one internal cavity. The plate is immersed in the suspension to be treated. The plate is inclined with respect to the vertical and only a lower inclined face of the plate is covered with a filter medium, the upper face being solid. The compartment of the cavitied plate communicates with a conduit which collects filtered suspension. Gas flushing pipes are positioned below the plate for emitting gas bubbles that pass across the filter medium and remove material clinging thereto.

Abstract: A water purification device comprises a raw water channel forming plate extending spirally along the inner wall of a filter tank. A collector for collecting filtered water, positioned in the layer of the filter medium substantially at the center of the raw water channel forming plate, is also disclosed. Since the raw water is filtered from the periphery of the layer of the filter medium and the continuous raw water channel formed by the spirally extending raw water channel forming plate enables the number of influx points of raw water into the raw water channel to be reduced to one at a minimum, the structure is simplified and manufacture costs are reduced.

Abstract: A filtration method employs a water tank, a filtration tank within the water tank and provided with a filter material for straining solids from sewage supplied to the water tank, to produce filtered water within the filtration tank, a shield or guide plate encompassing the filtration tank adjacent the filter material to provide a liquid flow passage therebetween, and a bubble generator having a plurality of openings for generating bubbles within the flow zone, so that the bubbles pass along the filter material. Sewage water that is supplied to the water tank is conducted to the flow zone where part of the water passes through the filter material and solids suspended therein are strained out and attached to the outer surface of the filter material. The generated bubbles passing through the flow zone create a difference in pressure between a point at which the fluid including the bubble is flowing in the water flow zone and an opposite point within the filtered water chamber of the filtration tank, which will dislodge the solids attached to the filter material and prevent clogging of the filter material so that the filtration and passage of bubbles may be continuous without clogging.

Abstract: A media retention plate for an underdrain system having one or more filter blocks. The plate can include a first slot configured to allow the passage of air and a second slot configured to allow the passage of water during an air backwash. The media retention plate is configured to facilitate the water to flow back into the one or more filter blocks through the second slot while maintaining air flow through the first slot to create an optimal collapse pulse. The first and second slots are evenly sized and evenly spaced apart to facilitate the creation of a relatively smaller-sized collapse pulse during a sequential air-water backwash. A plurality of inserts can be arranged along a perimeter of a basal portion of the bottom surface of the media retention plate. The inserts improve the structural integrity of and prevent uplift of the media retention plate.
