    Abstract: The filtration system provides a long horizontal flow path through buoyant filter media. The filter media is contained in a vessel and the relationship between the water level in the vessel and the amount of filter media is such that the media extends completely across the horizontal flow path of the water during the filtration mode of operation. The system is configured so that the buoyant media volume expands during a cleansing mode of operation.

    Abstract: An apparatus for separating suspended solids from a liquid includes a tank, a floating bed of granular filter material held at the upper portion of the tank at the time of filtration, a feed pipe for feeding the liquid at a position between a filtering section and a sedimenting section, a hollow member or members which are arranged within the tank at a position below the position of the filter bed but above the position of the feed pipe, an air supply pipe which blows air up through the hollow member or members, thereby creating a turbulence required for effective backwashing, an arrangement for bringing the filter bed down to a position where the lowermost surface of the filter bed is held below a position substantially flush with the top end of the hollow member or members, a means for discharging a filtrate from the tank which is arranged in the top portion thereof, and a means for discharging a deposit of the suspended solids from the tank, which is equipped at the bottom portion thereof. The backwashing is carried out when the filter bed comes down to a desired level by blowing air from the air supply pipe through the hollow portion of the hollow member or members, thereby creating a turbulence in the filter bed and consequently removing the suspended solids entrapped in the interstices between the filter material particles. The water rinsing may be coupled with the air blowing.

    Abstract: A single chamber filter module containing a buoyant bed of filter particles through which the fluid to be filtered is passed in an upward direction through the bed so that the solids become trapped within the bed. The filtrate is withdrawn from the upper end of the module. Periodically, the filter bed is rehabbed by dispersing the bed, washing the entrapped solids from the particles and discharging the solids from the lower end of the module.

    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: Apparatus for separating solid particles, such as amalgam waste from the waste water from dentists' surgical units, employs at least one filter body through which the liquid flows and which consists of a filter medium enclosed between two perforated walls, and at least one sedimentation zone. The filter medium consists of balls of alumina having a diameter of 0.05-15 mm and a density such that the balls float in or are carried along by the liquid flowing through the filter body. The balls, which do not fill out the entire volume between the perforated walls (although they fill out the cross-sectional area of the filter body), rub against each other in the flowing liquid, so that the filter body is self-cleaning.

    Abstract: An apparatus includes a waste-movement system having a bed-support assembly configured to receive, contain and support an aquarium bed of an aquarium. A vibration-source assembly is configured to be positioned relative to the bed-support assembly. The vibration-source assembly is also configured to selectively generate and transmit vibrational energy to the aquarium bed while the aquarium water is made to flow. This is done in such a way that the gravel of the aquarium bed becomes, at least in part, spaced apart (at least in part) from one another; and the aquarium water, at least in part, moves (at least in part) the liquefied waste and the solid waste through the aquarium bed from a first interior section to a second interior section of the aquarium.
