Abstract
A mixing apparatus for generating and mixing gas bubbles into an aqueous solution includes a structure defining an interior fluid-flow chamber that extends along a longitudinal axis between an input port at a liquid input end and an output port at a liquid output end. The structure includes a gas injection portion located upstream from the liquid output end and a mixing vane portion extending in the downstream direction from the gas injection portion. The gas injection portion defines a gas injection lumen and a first region of the interior fluid-flow chamber, while the mixing vane portion defines a second region of the interior fluid-flow chamber. The first region of the interior fluid-flow chamber includes a plurality of side fluid-path lumens that extend alongside a first part of the gas injection lumen. This first part of the gas injection lumen and the side fluid-path lumens merge with a downstream fluid-path lumen of the first region.
