Abstract: In a wastewater treatment plant a clarifier is fitted with piping and a pump to withdraw settled sludge from the bottom of the tank upwardly through the tank's center column and radially out from the clarifier via an exit pipe above the liquid level. The exit pipe can be supported on a fixed walkway. At the bottom end of the central tower is a manifold device for collecting settled sludge, including an annular preferably cylindrical wall, a central pipe hub and at least one pipe branch extending from an opening in the cylindrical wall radially inwardly to the central hub. Sludge is drawn up through a vertical sludge return pipe by a pump located preferably above the tank's liquid level, drawing sludge into pipe branches of the manifold device and through the hub to the sludge return pipe, then out through the exit pipe.

Abstract: 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.

Abstract: The invention pertains to a process for in-situ regeneration of activated carbon loaded with trihalomethane (THM). Based on the invention, this is achieved with alkaline hydrolysis of the THM with increased temperatures within the activated carbon in halogen-free, good water-soluble, or gaseous compounds. After completion of the chemical hydrolysis treatment, the activated carbon is cleared of reagents and reaction products by rinsing with water and diluted acids, and is then available for reloading in the untreated water flow. During the entire cleaning process, the activated carbon bed must not be moved.

Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.
