    Abstract: An intermittently operating slow sand filter uses the damming of water in a raised pipe to provide a constant level of water in a slow sand filter container. The container includes a water inlet and outlet, and is partially filled with sand or other filter material. A pipe from the water outlet in the slow sand filter is raised upward to the desired level of water over the sand before descending to a water reservoir. Water backs up in the pipe and the container to the desired level above the top of the sand, even when the flow of water is intermittent. The schmutzdeuke forms at the top of the filter medium. The water level in such a manually operated slow sand filter, using fine quartz sand as the filter medium, and at ambient temperatures (about 21.degree. C.) is maintained above about 1 cm above the top of the filter medium and below about 8 cm above the top of the slow sand filter.

    Abstract: A storm drain filter is sized to cover the opening of a storm drain. It includes a top debris tray removably positioned within a bottom media tray. Each tray includes a peripheral trough surrounding a central overflow opening. The top tray is shorter in height than the bottom tray, so that a filter media receiving chamber is defined between the top tray and the bottom tray. Filter media is positioned in the filter media receiving chamber. A handle is attached across the central overflow opening of the top tray. In a first embodiment, the bottom surfaces of the top and bottom trays are perforated. In a second embodiment, the inner walls of the top and bottom trays are perforated. In either embodiment, water flowing into the filter is distributed around the top trough, passed through the perforated surface of the top tray, the filter media, the perforated surface of the bottom tray, and into the storm drain. Hydrocarbons and other contaminants are filtered by the filter media. Large particles and debris are collected in the trough of the top tray. The filter may be easily cleaned by lifting out the top tray, shaking out the debris, and replacing it in the bottom tray. The removable top tray also enables easy inspection or replacement of the filter media.

    Abstract: The water screening apparatus of the invention includes a conduit in which is positioned a discharge pipe opening through which water flowing in the conduit is to be dispatched completely during normal water flow conditions. The discharge pipe opening is positioned adjacent the conduit bottom wall portion so that as long as the water level does not rise above it, the water is completely dispatched therethrough. A bar screen is transversely disposed inside the water conduit and downwardly slopes from the conduit upstream end to the discharge pipe opening and covers the whole conduit width. When the water level rises above the discharge pipe opening, the water flowing above the discharge pipe opening will flow through the bar screen, the latter intercepting any macroparticles beyond a set threshold level carried by the water flow. These intercepted solid particles will slide along the bar screen under the pressure exerted by the water flow, to be carried in this way into the refuse discharge pipe to be disposed of along with part of the water flow. This way, during water overflow conditions, even if the water is not completely disposed of by means of the discharge pipe opening, the overflow water will not carry large solids or suspended matter, since it will be screened before being conveyed elsewhere, for example to a river.

    Abstract: A replaceable filter cartridge for use in a fluid filter assembly includes a substantially cylindrical filter element including a pair of oppositely disposed filter element ends. A first endplate is bonded to one of the filter element ends so as to close the end and prevent fluid leakage therethrough. A second endplate is bonded to the opposite filter element end so as to close the opposite end and prevent fluid leakage therethrough. The second endplate includes an outer annular wall which is sized so as to create a noticeable distance of separation between the second endplate outer wall and the outer surface of the filter element and thereby define an annular clearance space therebetween. The outer wall of the second endplate is annular and substantially concentric with the filter element and provides a lip or free edge for the snap-on assembly of a closing lid member. By configuring the lid member with a series of snap-over fingers, it is possible to simply snap the lid onto the second endplate and thereafter use the lid for handling and manipulation of the replaceable filter cartridge.

    Abstract: A reactor for conducting a continuous multi-phase catalytic reaction such as the conversion of syngas to higher hydrocarbon fuels. Gaseous reactants are introduced via a gas-permeable plate into a slurry which includes the product and a finely divided catalyst. The liquid product is separated from the remainder of the slurry by means of a filter unit including a filter member. A pressure differential is established across the filter member by means of a constant level device within the filter unit which maintains a level of filtrate within the filter unit below the level of the slurry. The slurry is maintained in a constant state of agitation by the introduction of the gaseous components as a steam of bubbles. Fluctuations in the pressure differential across the filter member prevent the filter member from clogging and the gas spaces above the filtrate and the slurry are in communication.

    Abstract: A device for the distribution of water to be treated into and for the recovery of washing liquid from a water treatment filter apparatus of the type including a tank containing therein a filter material includes a channel coupled to and extending along the length of the tank, the channel receiving therein water to be treated. The channel has an opening into the interior of the tank at a level above the filter material. The opening is defined at the lower portion thereof by an overflow over which the water to be treated flows from the channel to the tank. The overflow includes a first inclined plane inclined downwardly and away from the channel in a direction toward the tank and a second inclined plane inclined downwardly and toward the channel from the first inclined plane. The inclined planes extend into the tank and form a deflector structure to prevent any filter material from passing through the opening during backwashing of the filter material.

    Abstract: A method and apparatus for filtering suspended solids from a liquid suspension such as sewage, wherein the liquid to be filtered is forced upwardly through a filter media. Upon leaving the filter media, the filtered liquid flows over a weir and into an effluent trough, from where it is directed to an outlet conduit for suitable disposition. The solids entrapped in the filter media during the filtering process are removed therefrom by a cleaning or washing process, which simply involves increasing the rate at which the liquid is passed through the filter media. During washing, the liquid, such as water, is forced through the filter at a rate of flow equal to several times the rate of flow the water moves during filtering, which acts to fluidize the entrapped solids removed from the filter media, enters the effluent trough located above the filter media and because the rate of flow is higher than that during the filtering process, is directed into a compartment spaced away from where the filtered water has been directed. The washwater may then be re-directed through the treatment plant, or to other suitable disposal. The washing operation of the filter can either be pre-set to take place at specified time intervals, or can be initiated upon the establishment of a predetermined back pressure in the filter inlet resulting from clogging of the filter by the solids removed from the water being filtered.
