Abstract: The present invention is a device and method for clearing debris from fluid channels. In one embodiment, the device has a fixed screening member that is permeable in part wherein debris will collect. A movable scraper then scrapes along the screen and removes the debris therefrom and transports the debris to a desired location. In embodiments of the invention, the surface that comprises the screening member may be arcuate, and may be a surface of revolution. Different portions of the screening member may or may not be permeable. The invention may also include an overflow mechanism where overflow water is diverted into a separate unscreened fluid stream. Further, the invention may be suitable for use within a sump.

Abstract: A filtering apparatus for filtering sand, other debris, and pollutants from rainwater does not utilize electricity or complex valves. The apparatus includes a tank, preferably concrete, having at least one inlet, an overflow outlet, and a filter proximate the tank outlet. The overflow outlet in one embodiment comprises an overflow weir having at least one side and an open top. A screen is attached to the top of the overflow weir and/or the tank outlet, and is preferably made from stainless steel or plastic. The screen is preferably sized to filter sand. In use, rainwater enters the tank, debris settles, and water exits the outlet and the filter. When a large amount of fluid enters and fills the tank, the fluid level reaches the overflow. At this point, any excess rainwater that cannot exit through the screen will flow over and into the overflow opening and exit the tank outlet.

Abstract: The present invention provides a concentration type aggregation reaction apparatus having a concentration screen, which enables an aggregation reaction to be conducted in sludge and the sludge to be concentrated by separation of a liquid by means of a single apparatus. The concentration screen is in a cylindrical form and includes slits having horizontal openings. A decelerating device is connected to an upper portion of a shaft for an agitator for agitation in the tank and brushes are connected to the decelerating device. The brushes are adapted to revolve along opposite surfaces (on a primary side and a secondary side) of the screen. By use of these brushes, aggregates adhered to the screen are continuously removed.

Abstract: A concurrent backwash distribution apparatus for a filter having a filter tank and a plurality of underdrain laterals includes a baffle positioned in a common main conduit to define an auxiliary flume between the baffle and the underdrain laterals. The auxiliary flume is in fluid communication with the common main conduit and the underdrain laterals. The baffle has at least one flume liquid metering orifice preferably located near the bottom of the baffle so that it may be below a gas/liquid interface in the auxiliary flume during concurrent gas/liquid backwash operations. A flow distribution plate may be positioned between the auxiliary flume and the underdrain laterals, the flow distribution plate having at least one liquid metering orifice and at least one gas metering orifice. The baffle may take one of many forms. The baffle creates an adequate liquid pool in the common main conduit for low velocity flow of backwash liquid while at the same time providing uninhibited flow of backwash gas. Maldistribution is thereby controlled. Stand-pipes may be used in place of the baffle. A method for concurrent gas/liquid backwash according to the invention is also disclosed. The invention may be applied to flat bottom flumes or insufficiently recessed flumes.

Abstract: A filter and a method for filtration is based upon moving a filter surface that is caused to move through a first filtration region (FF) for separation of a prefiltrate and through a second filtration region (KF) for separation of a clear filtrate. A vacuum is applied on the filtrate side of the filtration region (KF). The filtrate region (FF) has two filtration zones (FF1 and FF2) with mutually different pressure conditions. The filtration zone FF1 has atmospheric pressure and the filtration zone FF2 has a pressure that is lower than the pressure of FF1. The pressure change between the filtration zones (FF1 and FF2) occurs in the pre-filtrate region, i.e., before the filter surface has reached the filtrate region (KF).

Abstract: An apparatus for associating a solution at an infinitely-variable level and/or flow rate with respect to an agent including an agent amount indicator that promotes agent-solution association adaptable for use in a chlorinator, or comparable component, of a fluid treatment plant. An embodiment configured according to the invention includes a chamber with an inlet and a vertically-inferior outlet. The level and flow of fluid in the chamber is regulated by a weir mounted on the outlet. Fluid in the chamber passes through an agent the retainer maintained in the chamber and washes over the agent, dissolving and depleting the agent. A magnetic follower on top of the agent urges the agent toward the bottom of the retainer. As the agent becomes depleted, the follower approaches the bottom of the retainer until it attains a predetermined distance from a sensor which activates a low-agent-supply alarm.

Abstract: A skimmer assembly is used in a swimming pool having a water surface, a return inlet and a wall. The skimmer assembly includes an elongate container defining a channel therein. The container has a first side opposing a second side. The first side defines a substantially horizontally oriented, elongate cutout therein. The cutout is in communication with the channel and is configured for communication with the water surface. The cutout has an upper edge and a lower edge. The container has a substantially open first longitudinal end and a substantially closed second longitudinal end with a nozzle disposed therethrough. The nozzle is aligned substantially parallel with the channel and has an opposing inlet and outlet. The outlet of the nozzle tapers toward and is in communication with the channel. A porous trap having an open mouth is connected to the open first end of the container. An elongate, semi-flexible hose is disposed outside the container and is connected with the inlet of the nozzle. The semi-flexible hose supports the container such that the upper edge of the cutout is maintained above the water surface and the lower edge of the cutout is maintained below the water surface. The semi-flexible hose can be manually adjusted to thereby reposition the container.
