Abstract: An upflow filter of the type in which a liquid influent (e.g. water) is directed upwardly through buoyant filter media particles includes a porous supporting member, preferably in the form of a screen having openings through it that are larger than the nominal size of the media particles. A layer of particulate material is positioned on the upper surface of the porous supporting member and has a nominal particle size that is greater than the size of the openings through the supporting member. This layer of particulate material includes a plurality of interstices, or passages through which filtered liquid influent can pass, and, in the most preferred embodiment, also retains the buoyant media particles in the filter.

Abstract: An upflow, buoyant media filter for industrial and municipal water and wastewater treatment is disclosed. The filter bed is supported in a tank such that there is defined an influent reservoir below the filter bed and an effluent reservoir above the filter bed. By inducing a continuous circulating flow of influent within the influent reservoir, the waste is slowly agitated allowing it to coagulate. As the waste particles are carried to the relatively quiescent areas near the perimeter of the tank, those that are heavy enough settle to the bottom of the tank. The lighter particles are carried along in the circulating flow to continue the coagulation process. Waste particles which do not settle out are ultimately removed by the filter media. As the waste particles build up on the surface of the filter media, they agglomerate. As their density increases, these particles tend to drop off of their own weight or may be scoured off by the circulating flow of influent. This self-cleaning process permits less frequent backwashing of the filter.

Abstract: A filter module wherein the fluid to be filtered is projected into a chamber containing a floating bed of buoyant bodies confined within the chamber at the top side and wherein the point of entry of the fluid is constantly moved about the center of the bed so that successive portions of the bed are subjected to weltering while the remainder is quiescent such that the solids are separated from the bodies dispersed by weltering and gravitate to the bottom of the module and are drawn off and the filtrate is drawn off through the quiescent portion of the bed at the top.

Abstract: A process and apparatus for cleaning contaminated raw water, in which raw water and a flocculator are introduced into the reaction space of a pressure vessel, which vessel has such reaction space at the bottom thereof, a filter space above the reaction space and containing a filter made of particles of elastic, granular material, and a clean water space above the filter space so that the raw water passes through the three spaces, whereby the pollution material contained in the raw water becomes enclosed by the cells of the floccules of the flocculator and the floccules become absorbed by the filter particles. Accumulated pollution material is removed from the filter particles by regenerating the filter with a fluid flowing from the clean water space through the filter space into the reaction space. The required extent of purity is achieved by varying the velocity of the raw water introduced into the reaction space, to thereby adjust the percentage of the voids in the filter.

Abstract: This invention describes apparatus and process for filtering liquids by employing a vertical cylindrical container divided by an immovable non-porous plate into a separate top and bottom chamber with each chamber containing a bed of filter material. The liquid to be filtered is passed upwardly through the buoyant filter material of the top chamber and then passed in series through the filter material contained in the bottom chamber. Conduit means for passing the liquid from the top chamber to the bottom chamber is located internally of the cylindrical container; passing directly through the said immovable separating plate.

Abstract: A liquid filtering method for operating an apparatus comprising a deep bed of dual, vertically separate, granular filter media beds. The first filter media bed has relatively coarse, light grains, e.g. in a size range of 0.050 to 0.375 inches and having a specific gravity in the range of 0.9 to 1.6. The second filter media bed, which underlies the first bed, has finer, heavier grains which have a specific gravity greater than 2.1. During filtration, after flow downwardly through the first bed, a substantial portion of the partially filtered liquid is intercepted and directed upwardly through the second bed to a clean liquid outlet located within the depth of the second bed. The remainder of the partially filtered liquid continues to flow downwardly into and through the second bed to the same outlet. Upon backwashing, the first bed is slurried and turbulently recirculated through a path external of the retaining vessel, while the second bed is only expanded. After backwashing, the filter media beds assume their original respective orientations.

Abstract: An apparatus for treating water includes a vertically extending contact vessel, wherein water is contacted with ozone, and a return vessel which contains a column of water of a sufficient height to drive water through downstream filtering stages. Ozone is removed from the water and the rate of ozone injection is monitored and automatically adjusted so that no great amount of ozone remains in water entering the filtering stages. The ozone is generated in elongated elements that are cooled by the process water and that are positioned to serve as a static mixer for such water.

Abstract: The invention concerns a method of separating solids from liquids for use with liquids containing solid components (for example, for filtering effluent) and/or for separating emulsions such as oil-water emulsions. It is proposed that a filter layer (3) consisting of thin, film-like filter particles should be used. These filter particles can be retained by sieve floors (4), thereby permitting the use of non-standard regeneration techniques such as very rapidly siphoning off the liquid enriched with the solids and/or emulsified droplets, drawing it rapidly through a drainage pipe (5), and increasing the pressure in the gas chamber of the filter.

Abstract: A liquid purification system using buoyant filter media for removing suspended solids from liquid comprising a vessel having a wastewater inlet and a clarified effluent outlet. Baffles are provided in the vessel to define an upflow region for the wastewaters over a weir into a downflow region for subsequent removal by the effluent outlet. Buoyant media is provided in the upflow and downflow regions where the buoyancy of the media in the upflow region carries some of the buoyant media over into the downflow region until equilibrium is reached. A device may be provided for the continuous removal, washing and return of buoyant media to the system.
