摘要： A method and system for controlling dissolved oxygen levels in a secondary treatment system of a wastewater treatment facility that can employ a membrane bioreactor in which oxygen introduction into mixed liquor is controlled to prevent bulking and minimize generation of extra cellular polymeric substances. The control is exercised by insuring that dissolved oxygen levels within the mixed liquor do not fall below a minimum system level at which microorganism stress would occur. This is done by setting a minimum dissolved oxygen level control point equal to a sum of the minimum system level and an adjustment factor determined on the basis of oxygen uptake rate and time delays inherent in sensing oxygen levels and changes thereof within the mixed liquor. The minimum system dissolved oxygen level can be continually calculated on the basis of an inferred food to mass ratio that would vary with sensed mixed liquor suspended solids.

摘要： 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.

摘要： A method and apparatus for injecting a gas into a liquid in which a rotating helical impeller within a draft tube submerged in the liquid creates a liquid flow within the draft tube. Gas bubbles are injected into the draft tube either above or below or alongside the helical impeller or in all three locations. The liquid is drawn into the draft tube with a superficial velocity greater than a substantially uniform terminal ascent velocity of the gas bubbles to allow entrainment of undissolved gas bubbles in the bulk liquid into the liquid being drawn into the draft tube. The gas bubbles are injected with a uniform diameter of between about 10.0 microns and about 1.0 millimeters. The small bubble size enhances the dissolution of the gas into the liquid and also allow the entrainment of the gas into the liquid being drawn into the draft tube.

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.

摘要： A surface aerator for mixing gas and liquid is disclosed. The surface aerator has an upwardly pumping impeller located within a draft tube. A flow diverter redirects pumped liquid from the impeller traveling in an upward direction to a radially outward direction where it impacts and aerates the remaining liquid in a vessel. A baffle extends radially at a shallow depth to a point beyond the impact area of the liquid to provide separation of the impact area from the rest of the liquid and promote aeration.
