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: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic media will become "spent" and at a certain "spent level", the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the "spent" organophilic media should be replaced with fresh media or the spent media regenerated.

Abstract: The filtration apparatus of the invention is of the type having one or more of upright tubular filter elements with the surface coated with a pre-coat layer of a filter aid through which a liquid is filtered. Different from conventional apparatuses, the filter element in the inventive apparatus is provided with a gas exhaust tube or liquid drain tube connected to the upper or lower part of the element. 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 causing no defects in the pre-coat layer.

Abstract: Apparatus and for the treatment of storm water runoff to remove contaminants that accumulate in the storm water when it flows over paved surfaces in urban areas. The apparatus includes a basket that has an outer surrounding water-permeable wall, and an inner water-permeable wall, spaced from and surrounded by the outer wall. A bed of an absorbent, able to absorb contaminants in the storm water, is disposed in the space between the outer and inner walls, while allowing fluid communication between the walls. An inner drainage space is defined by the inner wall and is in fluid communication with the absorbent. During operation, storm water flows through the outer permeable wall, into the bed where it is treated; and treated water flows from the bed through the inner wall into the inner drainage space. Treated water then flows from the drainage space, in some embodiments under a siphon-effect, into a treated water drainage conduit for disposal. The absorbent may be selected from compost, vermiculite, activated carbon, peat, ion exchangers, clays, and the like, and may be in the form of pellets or particulates. The baskets are of modular construction so that the beds are in containers that may be removed and replaced, with minimal labor. Moreover, the baskets may be backflushed to remove particulates and debris that clog the beds and retard the treatment rate.

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.
