摘要： A method and system for treating wastewater is disclosed. In one example the method comprises activating a mixing system that imparts a motive force on wastewater in a vessel, measuring at least one property of a first portion of the wastewater at a first time, measuring the at least one property of a second portion of the wastewater at a second time subsequent to the first time, calculating a difference between the at least one property measured at the first time and the at least one property measured at the second time, performing a determination of whether the difference is within a predetermined allowable range of differences, and responsive to a result of the determination, controlling a component of the mixing system.

摘要： A 3D printing system comprises a pressure system to provide a negative pressure and a hopper having a first opening to receive powder to be used for printing, wherein the powder is received in an open state of the first opening. The hopper has a second opening to guide air from outside the hopper to inside the hopper and has a third opening connected to the pressure system so as to provide for a negative pressure inside the hopper, the negative pressure to overcompensate for the air receive through the second opening such that a pressure being lower when compared to an ambient pressure of the hopper is generated inside the hopper.

摘要： A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

摘要： An air-stirred tank reactor (ASTR) and methods of use thereof are described herein. The ASTR is equipped with an impeller or set of impellers that mechanically mixes a liquid culture, as well as sparges gas into the liquid medium. The impeller can further have lighting sources that can illuminate the liquid culture. Unlike conventional bioreactors, the ASTR provides superior liquid mixing, efficient gas mass transfer, and a low-shear culture environment through appropriate impeller rotational speed and sparging rate.

摘要： Fine-bubble-producing aeration units and large-bubble-producing (or other mechanical) mixing units are interspersed with each other in a given body of water to be treated. The two different types of units are independently controlled to independently regulate degrees of aeration and mixing in the given body of water.
