摘要： This invention relates to a trap for removing solid particles from a liquid flowing in a conduit. The trap comprises a filter element disposed across the conduit at an angle sloping rearwardly with respect to the direction of liquid flow in the conduit. A receptacle communicates with the conduit rearwardly adjacent to the lower end of the filter element.

摘要： In a system wherein a closed vessel is divided into several compartments, including a charging compartment and a washing compartment, which are successively traversed by an array of filter vanes rotating about an axis, air from a compressor maintains a constant pressure in the vessel whereas the pressure differential effective across the filter screens of the vanes is varied by regulators responsive to the rate of filtrand supply (in the charging compartment) and to the composition of the existing wash water (in the case of the washing compartment).

摘要： An inlet conduit in the form of a rigid, perforated support for gravel in the base of a fishtank is communicatively connected to a chamber having a first portion housing filter means and two second portions on opposite sides of the filter means. A tube formed with apertures throughout its entire length extends longitudinally across the lower end of a convergent nozzle which has an elongate cross-section and extends upwardly from the filter means. The tube is supplied with pressurized air through a hose and, as a result, air bubbles issue at a uniform rate across the whole width of the nozzle and, as these bubbles pass upwardly through the nozzle, induce flow of water through the gravel, through slots formed in the inlet conduit, and through filtering material enclosed in the filter means to thereby clean the water drawn through the nozzle.

摘要： A filter system and method are provided utilizing a filter tank separated into an inlet compartment and a filtrate compartment by a filter media. Under normal filter operation, the liquid to be filtered enters the inlet compartment, is passed through the filter media and out the filtrate compartment by a pressure differential created across the filter media by a pump device. When the need arises to move the filter media as a result of the buildup of contaminents on it, it is necessary to alleviate the pressure differential across the filter media. Such pressure differential is alleviated by the controlled flowing of filtered liquid through an orifice in a closed valve into the filtrate compartment.

摘要： A filtering device including a tank partially located below floor level having a filtrate compartment and a filter means interposed therebetween. Reservoir means and an end suction centrifugal pump means both located substantially on floor level wherein conduit means selectively permits the filtrate level in the reservoir to maintain a positive pressure at the inlet of the pump when pump is shut off, and to neutralize the pressure differential between the filtrate compartment and the tank.

摘要： Waste water containing pollutants such as suspended solids and emulsified oil is pumped continuously through a self-contained separating or polishing system utilizing a simplified plug-in module to remove the pollutants. The suspended solids are removed by mechanical filtration and the emulsified oil is separated by coalescing oil into floatable droplets which can be skimmed from a water surface and withdrawn for external accumulation. The treated waste water may be returned for further use or pumped to other facilities for further treatment.
