摘要： A filter assembly has a compressible filtering medium (18, 19) disposed in the flow path of water from the upstream region of an inlet chamber (11) to a downstream outlet (17). Said compression of the filter medium by the water passing through the filter assembly increases the proportion of the overall flow path of water constituted by a low resistance portion of the flow path. The clogging of the filter medium thus leads to an increase in water pressure in the upstream region which, in turn, causes compression of the filter medium, which compression tends to increase the water flow rate through the outlet so as to counter the reduction in water flow rate causes by the clogging.

摘要： Disclosed is a container (1) for receiving a fluidized bed, comprising a turbulence chamber for receiving a medium that is to be vortexed, and a cushioning space (7) which is disposed below the turbulence chamber and is provided with an inlet (6) for a fluid that vortexes the medium. Said inlet guides the fluid into the cushioning space in such a way that a circular, upward-directed current is generated. Also disclosed are methods for backwashing a filter used for treating water.

摘要： The invention concerns a method and an installation for filtering liquid media, in a completely immersed filtering mass (MF), having a height (h), forming a channel and which consists in injecting raw water (EB) at one end (E), of said channel and at the surface of the filtering mass and extracting the treated water (ET) substantially at the other end (S) of the channel, the injection (E) and the extraction (S) sites generating at the surface of the filtering mass a liquid layer (N) capable of a horizontal motion (F1) from (E) towards (S); producing along the channel, a succession of (n) recycling loops to generate in the filtering mass a succession of (n) mutually adjacent columns (Cn) so as to generate between the intake and the exit of the liquid a general spiralling movement.

摘要： Apparatus for inhibiting fines carryover in the form of a settlement tank comprising: a filter which divides the tank into upper and lower portions; a fluid inlet in the lower portion for admitting into the tank a fluid with entrained solids; and a fluid outlet in the upper portion through which filtered fluid can leave the tank. The filter comprises filter media supported on a permeable wall, the wall including a filter media outlet which is normally closed, and opening means for opening the filter media outlet to allow the filter media to discharge into the lower portion of the tank. The invention also relates to a method of refilling the filter with filter media.

摘要： A filter assembly for filtering pond or aquarium water comprises a container (1,2) with an inlet chamber (15) having an upstream region (36) and a downstream outlet (13) leading to an outlet chamber (22). A filter (16) is positioned in the inlet chamber (15) between the upstream region (36) and the outlet (13). In use, progressive clogging of the filter causes the water pressure in the upstream region (36) to rise until it reaches a predetermined threshold when a normally-closed relief valve (28, 29) opens to allow water to pass from the upstream region (36) to the outlet chamber (22) without passing through the filter (16). The valve has a coloured valve stem (28) providing a visual indication that the valve is open and that the filter is blocked and requires cleaning. In one embodiment, the outlet chamber (22) contains a source (19) of ultra-violet radiation to which the flow of water is exposed, regardless of whether the valve (28,29) is in the open or closed condition.

摘要： A filtration device that enables efficient cleansing and rinsing of filtration media within a short time, in which filtration sand is not likely to become clogged, and in which unevenness within filtration sand is not likely to occur. A screw conveyor 32 is provided within a cleansing tank 38, which is suspended from the upper portion of a filtration tank 2. A space 52 is formed between a filter bed 4 and a wire mesh 50, which are vertically separated. Filtration media 14 is provided on the wire mesh 50, and filtration media 54, having larger particle sizes than the filtration media 14, is provided within the space 52. A plurality of strainers 12 are provided in the filter bed 4. Cleansing water spraying pipes 58 are provided on an outer wall surrounding the space 52. After the screw conveyor 32 is rotated and the filtration media 14 has been cleansed, cleansing water is sprayed from a filtered water discharge pipe 46 and the cleansing water spraying pipes 58, to expel contaminants through a raw water supply pipe 56.
