Abstract: The apparatus treats storm water and includes a cylindrical basket that has a housing with a circumferentially extending air slot near the base of the housing. The basket contains an annular bed of absorbent material surrounded by a filter cartridge. Water flows radially inward through the filter and the bed into a cylindrical inner drainage space which has an outlet at its lower end, covered by a float valve. The drainage space is also in fluid communication with a one-way valve that allows air to pass from the housing into the environment. During operation, the float valve lifts when the water level rises and air is expelled from the drainage space through the one-way valve. As a result, water is continuously siphoned through the basket apparatus. When the water level drops, air enters through the air inlet slot of the housing and rises in turbulent fashion along the filter, scouring the filter and dislodging particulates. As a result, the filter is cleaned and the infiltration capacity of the basket filter is maintained.

Abstract: 1469288 Filters; centrifugal separator RACOR INDUSTRIES INC 3 July 1974 [19 Nov 1973] 29513/74 Headings BID and B2P An apparatus for separating a mixture comprising fluids of different densities and solid particles, comprises an elongated body 10 having means 24 in a lower part thereof for subjecting the mixture introduced through inlet 18, to centrifugal force whereby the denser fluid and particles are discharged through passages 61 and the lighter fluid and particles are passed upwardly through passage 29 to a chamber containing one (or more) inward flow filter element(s) 40, through whichthe lighter fluid passes to outlet 19. Some settling may take place in funnel 30. The means 24 comprises a deflector member 55 having helically curved flutes 62 and a shield member 56. The inlet 18 is provided with a one-way ball valve 25. The filter element 40 (preferably containing resin impregnated cellulose) is mounted on outlet conduit 21 having two inlet openings 50 (only one shown) at its upper end, and is clamped between cap 39 and spring 43. The apparatus is mounted by brackets 16. The apparatus may comprise two bodies mounted in series, the filter element of the first body being coarser than the filter element of the second body, or in parallel, in which case each body may be used independently. The body portion 11 may have a sight glass for noting the level of separated denser fluid therein. The apparatus may be provided with means for sensing the level of separated denser fluid in portion 11, the sensing means when a desired level is reached, actuating a control device to open the valve at the bottom of portion 11 and to operate a pump for discharging the denser fluid.

Abstract: A filtration apparatus having one or more upright tubular filter elements having a surface coated with a pre-coat layer of a filter aid through which a liquid is filtered. Different from conventional apparatuses, the filter element of the present invention is provided with a gas exhaust tube or liquid drain tube connected to the upper or lower part of the filter element, respectively. By virtue of this means, the liquid used for forming the pre-coat layer as the suspension medium can be completely discharged out of the apparatus prior to introduction of the liquid to be filtered so that the liquid in the apparatus can be switched from the pre-coat forming liquid to the filtered liquid without producing a mixture thereof, and without causing defects in the pre-coat layer.

Abstract: A filtering system, especially for swimming pools, by which a liquid or gas may be cleansed of suspended particles by passing the liquid or gas, under a pressure differential, through a multiplicity of vertical, tubular filter grids, each of which holds an outer layer of a diatomaceous earth particles which transmits the fluid and captures the particles. Each time a filtering cycle is stopped, the diatomaceous earth particles fall from the grid units due to gravity and their interconnection in the coating layer. This prolongs the useful filtration time of the filter grid units before they need to be backwashed. The filter grid units are supported by a central manifold provided with a plurality of removable hollow arms which radially extend from a central hub, and have a plurality of threaded openings therein, spaced apart from one another along the length of the arms, for receiving respective mating threaded ends of the filter grid units and aligning them in a vertical array within the filter tank. Each of the grid units is comprised of a rigid, braided or woven sock-like pervious filter tube tightly fitted over a rigid, perforated tubular frame. This arrangement prevents the adjacent grid units from tangling and losing effectiveness and also permits quick, easy removal and/or replacement of individual filter grid units.

Abstract: A static screen has a plurality of screening bodies and a plurality of aeration devices downstream of the screening bodies. Each aeration device is associated with a set of one or more of the screening bodies. Each aeration device may be a pulsing aerator. The pulsing aerators do not all release air at the same time. Each screening body works through periods of dead end filtration separated by backwashing events. The backwashing events comprise introducing a slug or pulse of air into the bottom of the screening body. Flow through the static screen continues at all times because the screening bodies are not all backwashed at the same time. The static screen may be used to remove trash from water flowing to an immersed membrane unit. Alternatively, the static screen may be used to provide primary wastewater treatment.
