<p>Improved Swing Diffuser A swing diffuser apparatus for gas diffuser systems for liquid treatment is disclosed in which an array of diffusers (50) is movable between a deeply submerged, essentially horizontal operating position, a shallowly submerged, essentially horizontal operating position, and a fully exposed, substantially upright position at the edge of the container for the liquid. An articulated hanger arm linkage (22, 24, 26, 30, 32. 52, 54) rotates the array to achieve these positions as the linkage folds and unfolds.</p> |
