摘要： The inventions describe a phased activated sludge treatment system that incorporates elements of batch treatment technology into a flow-through treatment process. Control of mixing and aeration systems are independent to facilitate the operation of the main reactor vessel in alternating aerated and anoxic conditions. Conditioning vessels in communication with the main reactor are employed to preferentially control the distribution and balance of nitrogen and phosphorus compounds in the reactor and to remove such biological nutrients concurrently with BOD and TSS in the wastewater. The inventions provide the beneficial results of providing greater operator control of flow-through treatment processes, power saving and reduced operation and maintenance costs in comparison to conventional flow-through treatment technologies.

摘要： A system for wastewater treatment comprises a tank and includes a mixer that generates large mixing bubbles, for example a bubble having a largest dimension of 6 inches to 10 feet. In some embodiments, the mixer is located in the anoxic zone. The mixing bubbles are large enough to move wastewater as they rise to the surface and generate a mixing current in the wastewater. The mixing current mixes the wastewater, and bacteria and other microorganisms to promote the bacteria and other microorganisms' conversion of the pollutants contained in the wastewater. The system further comprises an Integrated Fixed-film Activating Sludge (IFAS) system.

摘要： A system for treating wastewater containing organic compounds is provided, comprising an anaerobic bioreactor, an aerobic bioreactor disposed rearwardly of the anaerobic bioreactor, and a membrane separation reactor disposed rearwardly of the aerobic bioreactor. The system is capable of removing organic pollutants in wastewater through biological treatment process and separating solid from the liquid ones by using a membrane. By employing the system for treating wastewater containing organic pollutants, organic pollutants can be effectively eliminated and the problem of scaling and fouling on the surface of the membrane prevented, thus achieving the objectives of lowering cost and improving efficiency.

摘要： The specification discloses a method for treating and digesting organic wastes in a wastewater stream. A first wastewater influent stream is mixed with an activated sludge biomass in an aerobic digestion zone, so that least a portion of the organic wastes in the first wastewater influent stream are digested by activated sludge biomass. The first wastewater influent stream is separated from the activated sludge biomass in a first separation zone to recover activated sludge biomass and to provide a wastewater effluent stream. The second wastewater influent stream is mixed with recovered activated sludge biomass from the aerobic digestion zone in a substantially anaerobic adsorption zone so that at least a portion of the organic wastes in the second wastewater influent stream are adsorbed by the activated sludge biomass. The second wastewater influent stream and the activated sludge biomass are then separated in a second separation zone to recover the activated sludge biomass and organic wastes adsorbed thereto from the anaerobic adsorption zone and to provide a substantially liquid wastewater stream which is recycled to the aerobic digestion zone. Finally, at least a portion of the activated sludge biomass and adsorbed organic wastes from the anaerobic adsorption zone are digested under substantially anaerobic conditions so as to recover a combustible gas stream. An apparatus for carrying out the method is also disclosed.

摘要： A method is provided for maintaining a biomass disposed on a substrate in a bioreactor tank. The bioreactor tank has an inlet and an outlet in fluid communication with a waste treatment system whereby an influent fluid may be selectively introduced through the inlet into the bioreactor tank for removal of waste material therefrom. This produces an effluent fluid which can be returned through the outlet to the waste treatment system. The method comprises processing a quantity of influent fluid through the bioreactor tank to produce a quantity of effluent fluid and removing the effluent fluid from the bioreactor tank through the outlet. The method further comprises isolating the bioreactor tank from the waste treatment system and establishing a set of dry cycle conditions in the bioreactor tank. The dry cycle conditions are selected to effect endogenous growth within at least a portion of the biomass whereby an average age of the at least a portion of the biomass may be tailored. The method also comprises restoring the bioreactor tank connection to the waste treatment system.

摘要： Waste-treatment processes are enhanced through generation and introduction of specific biological populations customized to perform or favor specific tasks either during the main process, for the formation or precipitation of certain biological nutrients, or to accomplish solids formation reduction in a post-treatment process. These bacteria may be grown from specialized mixes of activated sludge and waste influent by exposing these materials to controlled environments (e.g., in an off-line treatment area). They may then be returned to the main process to perform certain tasks such as converting particulate cBOD into soluble cBOD for utilization, to reduce high solids yield organisms by supplementing the population characteristics with low yield organism characteristics, to provide biological nutrients or oxygenation assistance, to improve nitrification/denitrification efficiency, or to disfavor filamentous biology such as Norcardia sp.

摘要： Circulation systems for ponds, lakes, or other bodies of water using a flotation platform, dish, and impeller. One embodiment has a connecting arrangement between the drive motor and the impeller that permits the two to be easily and quickly coupled and uncoupled. The connecting arrangement also is designed to accommodate slight misalignments between the shafts. An arrangement to adjust and calibrate the depth of the inlet to the draft tube is disclosed. The system further includes solar panels that can be pivotally swung outwardly to open positions, angularly adjusted about a horizontal axis, and mounted to face toward the central axis of the flotation platform rather than away from it. Arrangements are further provided to monitor and control the components of the system including remotely from shore.
