20140158601 | TRAVELING BAND SCREEN, ASSOCIATED ROLLER AND RELATED METHOD FOR RETROFITTING A TRAVELING BAND SCREEN ASSEMBLY - A traveling band screen has a support frame assembly, two continuous chains movably mounted to the support frame assembly for motion along respective mutually parallel endless paths, a plurality of mesh members each secured on opposing edges to the chains, and a plurality of rollers rotatably mounted to each of the chains. One or more of the rollers are split rollers. Each such split roller has a respective rotation axis extending perpendicularly to the respective chain and accordingly to the path of motion of the chin. Each split roller has two roller halves secured to one another via elongate fasteners that extend parallel to the respective roller rotation axis. | 06-12-2014 |
20130256225 | Orbital Wastewater Treatment System and Associated Method of Operating an Orbital Wastewater Treatment System - An orbital wastewater treatment system generally including a tank assembly and at least one impeller in the tank assembly for moving mixed liquor under process about the tank assembly is provided with an wastewater inflow sensor, an impeller power meter, and a control unit for periodically and incrementally varying impeller speed and weir height in order to reduce energy consumption. Operating such a wastewater treatment system comprises flowing mixed liquor or wastewater into a treatment pool in the tank assembly, rotating the impeller within the pool to move the mixed liquor or wastewater, and adjusting, in concert, a rate of rotation of the impeller and a level or depth of the pool to reduce a rate of energy usage per unit inflow volume while maintaining at least one process parameter such as dissolved oxygen content substantially constant at a given level in the pool. | 10-03-2013 |
