Abstract:
A cover arrangement is provided for a launder channel of a clarifier tank. The clarifier tank has an arcuate outer circumferential wall and a weir wall, with the launder channel disposed between the walls. The cover arrangement has a single mounting section configured to be coupled to the arcuate outer circumferential wall and a plurality of cover sections, each of which are coupled to the same single mounting section at different locations. The cover sections are configured to extend from the arcuate outer circumferential wall inwards towards the center of the clarifier tank covering the launder channel.
Abstract:
A cover arrangement is provided for a launder channel of a clarifier tank. The cover arrangement includes at least one mounting section coupled to the clarifier tank near the launder channel. A plurality of cover panel members are provided, each panel member having a surface and two stiffening flanges located on opposing lateral edges of the surface, where each of the cover panel members further includes a light seal either one of attached to or attached near one of the stiffening flanges. The cover arrangement includes arranging the plurality of cover panels around the clarifier tank over the launder channel such that the light seal attached to or near the outer surface of the stiffening flange of a first panel member among the plurality of panel members abuts against a stiffening flange of an adjacent second panel member among the plurality of panel members.
Abstract:
A cover arrangement for an inboard launder channel includes at least one cover panel positioned over the inboard launder channel, having a first attachment portion and a second attachment portion. A first cover support bracket is coupled to a first upper side wall of the inboard launder channel and a second cover support bracket is coupled to a second upper side wall of the inboard launder channel. The first attachment portion is coupled at a first end to the first cover support bracket and at a second upper end is angled, inward towards the center of the inboard launder channel. The second attachment portion is coupled at a first end to the second cover support bracket and at a second upper end is angled, inward towards the center of the inboard launder channel. This allows a user to open the cover panel upward and away from one of the side walls of the inboard launder channel so as to clean the inside of the channel.
Abstract:
A cover apparatus for inhibiting the growth of algae on the fluid-contacting surfaces of a water treatment tank and for capturing noxious gases, the tank including a central influent, at least one substantially vertical peripheral wall having an upper and interior surface, a peripheral baffle having inside and outside surfaces, a substantially vertical weir, a spillway, and a launder channel having a width. The cover apparatus includes at least one panel member positionable over at least a portion of the launder channel to prevent light from reaching interior surfaces thereof. In an embodiment of the present invention, alternating covers are provided with a molded recess so that the covers may be mounted in end-to-end alignment to form a substantially sealed launder channel region.
Abstract:
A clarifier tank launder channel cover closure mechanism having a magnet, located at the top of a mounting bracket for supporting one side of a cover panel member, opposite its hinge mount across a launder channel of a clarifier tank. A magnetic element is attached to the cover panel member, and is located in corresponding location to the magnet, such that when the cover panel member is closed over the launder channel, the magnetic element and the magnet are in a mating relationship.
Abstract:
In this respect, the present arrangement provides a density current baffle that employs a baffle that is dimensioned to balance the fact that larger horizontal projections of density current baffles improve performance while simultaneously recognizing that an overly large baffle would simply not correctly function, be unnecessarily large and complex and may in fact have a negative impact on the otherwise ordinary operation of flows within the clarifier tank. Thus, the present arrangement provides a baffle that improves performance while satisfying the desire to remain conservative in defining an upper limit for the projection. The horizontal projection of the baffle is structured according to the following equation: HP=24″+0.4 inches/foot×(Diameter−30)

A cover arrangement for an inboard launder channel includes at least one cover panel positioned over the inboard launder channel, having a first attachment portion and a second attachment portion. A first cover support bracket is coupled to a first upper side wall of the inboard launder channel and a second cover support bracket is coupled to a second upper side wall of the inboard launder channel. The first attachment portion is coupled at a first end to the first cover support bracket and at a second upper end is angled, inward towards the center of the inboard launder channel. The second attachment portion is coupled at a first end to the second cover support bracket and at a second upper end is angled, inward towards the center of the inboard launder channel. This allows a user to open the cover panel upward and away from one of the side walls of the inboard launder channel so as to clean the inside of the channel.
Abstract:
A density current baffle for use in a clarifier tank has a first baffle portion having a lower end, an upper end and an intermediate central portion. The lower end of the baffle portion is coupled to a side wall of the clarifier tank. The upper end of the baffle portion being disposed away from the side wall of the clarifier tank. The intermediate central portion between the lower end and the upper end, the baffle portion is curved such that the upper end curves inward towards the center of the tank.
Abstract:
A vented baffle system for use in a clarifier tank having a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank is formed by a plurality of individual and cooperatively-engageable baffles mounted on the peripheral tank wall. Each baffle includes a panel member that downwardly slopes from the peripheral tank wall toward the interior of the tank and the tank bottom and terminates at a lower edge disposed in space relation above the tank bottom. A first lateral end of the panel member unitarily carries an end bracket securable to the peripheral wall for supporting the panel member in a cantilevered fashion. One or more of the baffles are provided with a relief valve means for venting the pressure in a space formed between the junction of the lower side of the panel member and the peripheral tank wall. The resulting system provides a vented baffle system in which pressure exerted by the build up of gases in the space may be alleviated.
Abstract:
A waste treatment tank cover arrangement is provided having at least one cover module having a cover section, a mounting section, and a hinge, where the cover section is pivotably mounted to the mounting section, movable between a dosed position and an open position. At least one cover module mounting bracket arrangement has a first L-shaped bracket connected to an inner side of a launder channel wall and a U-shaped mounting bracket conned to the first L-shaped bracket and extending upward, where the U-shaped mounting bracket connects to and supports the mounting section of the cover module. The position of the mounting bracket and connected hinge are such that the position of the hinge is inboard relative to the location of the weir such that when the cover section is in an open position, the weir is exposed and not hidden beneath the mounting section.
