Abstract: An upwash sand filter with a diaphragm hold-down for the granular filter media during filter stage is operable with self-graded coarse-to-fine media for upflow filtration, downflow filtration, or combined up and down flow to a central exit filtration. The media is held in place by a diaphragm that may be a perforated plate for allowing liquid to pass through the perforations, and in the downflow embodiment, the media column is supported on another perforated wall or plate to allow a final lower layer of coarser media to be used so that the plate itself is not the finest layer of the filter. In the upflow embodiment, a coarser top layer is employed for this same purpose. The diaphragm serves in all embodiments to prevent loss of media and avoid channeling through the media thereby allowing exceptionally high filter rates.

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 solids separation 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 solids separation 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: According to the invention, the enclosure (1) contains a granular material (4) having a specific mass less, or respectively greater than that of the liquid to be treated. When the liquid is admitted through an upper inlet line (2), a granular bed is formed at the bottom of the enclosure (1) or at the upper part thereof and the colloidal particles form aggregates there. When the supply of liquid to be treated is interrupted, the granular material rises to the upper, respectively lower, part of the enclosure (1) and releases the aggregates formed, which can be recovered.

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.
