摘要： An assembly for removing grit from a fluid comprising a tank with a fluid inlet into the tank and a discharge from the tank. A flow directing assembly is positioned in the tank adjacent the fluid inlet and includes a substantially U-shaped surface opposite the fluid inlet such that fluid entering the tank through the inlet is caused to have a reversed flow in a direction more than 90 degrees from an inlet flow direction. At least one embodiment of the assembly further comprises a baffle positioned proximate the tank discharge to control flow adjacent the discharge. Yet a further embodiment of the assembly includes a screw conveyor positioned in a trough of the tank and a baffle is positioned proximate the trough to minimize fluid flow velocity adjacent to the screw conveyor.

摘要： A method and apparatus for treating wastewater streams by adding, either separately or as a mixture, a nitrate containing compound and an alkaline material in an amount sufficient to achieve a lower concentration of atmospheric hydrogen sulfide and dissolved sulfides downstream of the addition as compared to the atmospheric hydrogen sulfide and dissolved sulfides present in the wastewater stream prior to the addition. By adding alkaline material in addition to a nitrate containing compounds, the amount of nitrate containing compound added can be reduced by at least 10% as compared to the amount of nitrate that would theoretically need to be added in the absence of alkaline material to achieve a comparable lower concentration of atmospheric hydrogen sulfide and dissolved sulfides in the wastewater stream.

摘要： The bar screen of the present invention includes a bar rack and a cleaning rake. The bar rack includes a plurality of aligned bars and is adapted to be at least partially positioned within the channeled water. The cleaning rake is movably coupled to the bar rack and includes a plurality of tooth segments. Each tooth segment includes a base portion and a plurality of teeth. The base portion is coupled to the cleaning rake, and the plurality of teeth is connected to the base portion. Each tooth of the plurality of teeth is adapted to be inserted between adjacent bars on the bar rack to remove debris that has accumulated on the upstream side of the bar rack.

摘要： The present invention is directed to a sludge collector for use with a circular clarifier. The circular clarifier includes a tank that has a bottom and a wall that extends upwardly from the bottom of the tank. The tank is configured to contain a solution and allow sludge to settle from the solution to the bottom of the tank. The sludge collector includes a withdrawal manifold, a scraper assembly, and an entrapment plate. The withdrawal manifold is located at the bottom of the tank. The scraper assembly extends from the withdrawal manifold toward the wall of the tank and moves the settled sludge toward the withdrawal manifold. The entrapment plate extends between the withdrawal manifold and the scraper assembly to trap sludge between the withdrawal manifold and the scraper assembly and funnels the trapped sludge into the withdrawal manifold.

摘要： A system and method for providing an oxidized liquid effluent stream substantially free of volatile compounds is provided. The system includes a stripper positioned downstream of a separator, or disposed within a separator. The method involves volatilizing volatile compounds by performing a separation followed by stripping, or in the same chamber as the separation. In another aspect, the invention involves adjusting the pH of the oxidized waste stream prior to stripping in order to convert ionic species to volatile species that can be removed by stripping.

摘要： Improved flow modifier assembly for a water intake system having a cylindrical intake screen prevents damage to fish and other aquatic organisms by providing a controlled velocity profile which causes the average flow velocity to closely approach the peak flow velocity. By extending two or more concentric tubular flow modifiers into one end of the screen, it is possible to achieve flow uniformities of more than 90%, as compared to a maximum of about 72% for a prior art configuration utilizing a single tube flow modifier. In addition, the size, weight and cost of screen required can be greatly reduced for a given peak flow velocity as compared to prior art devices.
