Abstract: Filtration apparatus comprises a column (1) having a lower liquid inlet (7), an upper liquid outlet (2), and an intermediate internal screen (4) adapted to confine a bed (5) of buoyant particles therebelow; means (8) adapted to cause liquid to flow up the column; and means (9, 10) adapted to expand the bed. Such apparatus can be used to remove biodegradable impurities from a liquid, by causing the liquid to flow up the column, the column including, below the or each screen, buoyant particles on which biomass will collect; and intermittently operating the expansion means. For example, an aeration pump may be operated such that, in normal flow conditions, the bed is substantially undisturbed, and intermittently such that the particles are less buoyant and biomass on the particles is removed by attrition as the particles circulate.

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 treatment tank (1) with a liquid inlet (2) contains a layer of components (4) having buoyancy in the liquid. During treatment the liquid is directed so that it premeates through the layer. During treatment the layer is stabilised by restricting the buoyancy of the layer in the liquid. This may be done by maintaining the level of the liquid below the surface of the layer with the outlet stand pipe (7). The layer filters the liquid of particles alone, or together with soluble material. When the apparatus is to be serviced for removal of particles from the layer the buoyancy of the layer is released. This provides for loosening of the components and the particles can be freed from the interstitial spaces of the layer. The particles are released to a position below the layer and may be discharged from the tank. The invention can for example be applied to the mechanical and biological filtration of impurities from waste water.

Abstract: A multi-bed filtration system includes an upstream filter bed in series with a downstream filter bed of nonbuoyant media. Also included is a system for periodically backwashing the nonbuoyant filter bed. Coagulant-treated water is passed through the upstream filter bed, followed by the downward flow of water through the downstream filter bed. Thereafter, the downward flow of water through the downstream filter bed is periodically interrupted. During these interruptions, a limited amount of water is introduced upwardly through the downstream filter bed by the backwashing system. Such backwashing frees coagulated solids within the bed, causing the solids to move upwardly through the bed. The solids ultimately collect in a zone above the surface of the bed. When normal filtration recommences, water passes through the deck of solids in the zone prior to entering the nonbuoyant filter bed.

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.
