    Abstract: In systems for treating wastewater liquid by utilizing aerobic biological species, the contaminated wastewater stream is pretreated in a dissolved air flotation system to remove suspended solid waste, including large particles such as fats, grease, and physically emulsified oils. The purified wastewater containing dissolved waste is thereafter gasified and further decontaminated in a bioreactor tank. Biological species in the bioreactor tank consume gas and perform bodily functions that converts dissolved waste into easily removable carbon dioxide and suspend solids. Gas consumed by the biological species is replenished by pumping the wastewater though a liquid-gas mixer. A controller regulates the speed of the pump based on real-time gas concentration measurements provided by a corresponding gas probe disposed within the wastewater in the bioreactor tank.

Air outlets of the manifold direct an air stream towards the outlet of the pipe to draw material through the pipe from a hopper of particulate material, the pipe inlet being located within the hopper. An air inlet valve in the air supply line is connected to a controller which is operable to open and shut the valve for pulsing the gas stream to control the amount of material delivered through the pipe.

    Abstract: An object of the invention is to provide a mixer and a mixing control method that enable to keep the driving efficiency of a motor high, and to flexibly follow a predetermined rotation speed of a mixing rotor pair, which is varied depending on various applications of the mixing rotor pair. A fixed speed motor is rotated at a constant rotation speed, and a variable speed motor is variably rotated at an arbitrary rotation speed. A difference in rotation speed between the fixed speed motor and the variable speed motor is supplied to the mixing rotor pair as the rotation speed by operations of a sun gear, a planetary gear, an internal gear, and a gear retainer of a planetary gear transmission.

    Abstract: The present invention relates to a wet-type recirculation system for particle size analysis of sample including coarse particles (hundreds to thousands ?m). According to the wet-type recirculation system of the present invention, the mixture liquid is recirculated using not a single recirculation line but two recirculation lines between the mixer and the particle size analyzer and the recirculation lines are connected with the mixer at the upper inputting part side of the mixer to discharge the mixture liquid. Further, the rotatable baffle is attached to the inside of the mixer to generate vortex in a horizontal direction as well as a vertical direction within the reservoir of the mixer and the baffle is rotated by a pressure of the mixture liquid discharged from the two recirculation lines to form vortex.

  • Publication number: 20080247265
    Abstract: The present invention provides an apparatus for the mixing or dilution of chemicals from one more sources that have been analyzed using laboratory analysis or an insitu-analyzer for concentration or molarity. The chemical is then transferred to a series of precisely calibrated vessels each of have a volume 10% of the next vessel. For example the main vessel may be 1 L in volume and the second vessel is 0.1 L in volume, the third is 0.01 L in volume and the fourth is 0.001 L in volume. The present system utilizes these two or more metered vessels which are connected to bulk chemical sources via intake lines. Each metered vessel contains an overflow tube, which drains any excess chemical by gravity flow from the metered vessel so as to adjust the chemical amount to a pre-calibrated desired level.

  • Publication number: 20080186801
    Abstract: A bubble micro-pump includes a first component, a second component and a bubble-generating unit. The first component includes a flow path having a first area and a second area. The second component above the first component has a first roughness surface and a second roughness surface. The first roughness surface opposite the first area has a first roughness factor, and the second roughness surface opposite the second area has a second roughness factor smaller than the first roughness factor. The bubble-generating unit on the first component generates bubble in the first area and the second area when a fluid fills the vacancy between the first component and the second component. Due to the difference in roughness factor, the backfilling velocity of the fluid in the first area is faster than that in the second area when the bubble starts to vanish, such that the fluid is driven to flow.

  • Publication number: 20080144427
    Abstract: A method and apparatus for combining and mixing together a plurality of liquids to form a blend. The invention discloses reservoir supplied intermittently operated servo driven pumps, and optionally discrete liquid flow meters, and precise, encoded, fast-acting flow shut-off devices to create and define repeated time synchronized ratio defined doses of the liquids. One or more liquids, designated secondary streams, are synchronously dosed into a secondary streams injection assembly which is located generally at the suction port of the primary liquid stream dosing pump. The primary stream pump, during its synchronized intermittent operation, withdraws ratio defined primary stream and secondary stream liquids from the injection assembly. The primary stream pump serves also to propel the combined liquids ratio dosed streams into and through mixing structure on the discharge of the primary stream pump.

  • Patent number: 7363115
    Abstract: There is disclosed a system and method of formulating a batch comprising at least two chemicals. An embodiment is disclosed wherein a feedforward algorithm can be used to control the target blend. Subsequently a feedback closed loop control loop algorithm is provided for a multivariant blend. Use of this approach allows for a continuously autoreplenished and controlled blend. Also disclosed is the ability to control via feedforward and feedback algorithms a fast responding control mode that allows for the elimination of a container. This approach will allow for “one pass” blending with control. The controller implements an automated fault detection and correction system, thereby identifying necessary maintenance prior to failure. If failure does occur the signature recognition allows rapid analysis and correction thus maximizing tool availability.
