Abstract: A filter assembly that filters water, particularly stormwater, that includes flow regulating, siphon inducing, and surface cleaning features that allow the filter assembly to operate at the design filtration rate for an extended period of time. During filtration, water flows inward through an annular filter medium into a drain manifold. The rate of flow into the drain manifold is controlled by a float valve assembly. A check valve permits air to escape, but not enter, the filter assembly creating a siphon effect when the rate of flow into the drain manifold is increased. The siphon effect draws water through the entire filtration surface and the entire volume of the filter medium. When the external water level decreases to the level of an array of voids in the filter assembly enclosure, the siphon is interrupted by turbulent air streams entering the filter assembly, agitating the filter surface and dislodging particulate matter.

Abstract: A filter and a method for filtration is based upon moving a filter surface that is caused to move through a first filtration region (FF) for separation of a prefiltrate and through a second filtration region (KF) for separation of a clear filtrate. A vacuum is applied on the filtrate side of the filtration region (KF). The filtrate region (FF) has two filtration zones (FF1 and FF2) with mutually different pressure conditions. The filtration zone FF1 has atmospheric pressure and the filtration zone FF2 has a pressure that is lower than the pressure of FF1. The pressure change between the filtration zones (FF1 and FF2) occurs in the pre-filtrate region, i.e., before the filter surface has reached the filtrate region (KF).

Abstract: A method and apparatus for cleaning cooling tower basins. The apparatus includes a reservoir and large pipe extending from the tower basin to a lower level to act as a siphon. A water supply can fill the large pipe, and a valve can be opened to start the siphon. A cleaning tool remains below the water level in the basin to maintain the siphon while the basin is cleaned. The makeup water valve maintains the desired water level in the basin, so the tower can remain in operation during cleaning. The material removed from the basin is strained and the waste water is disposed of through conventional sewerage.

Abstract: A method of operating a filter centrifuge or centrifugal filter in which a hydrostatic head is provided at the filtering surface so as to control liquid passage therethrough. The head may promote movement of the liquid through the filter layer or may induce reverse flow of liquid for backwashing or rinsing. In addition, a hydrostatic balance may be provided at this surface through control of the head to limit passage of the liquid through the filter layer. Preferably the head provides a suction augmenting centrifugal filtration.
