Abstract
A new accumulator for generating mixing bubbles comprises pivoting, counterbalanced buckets, the buckets receiving air directed from blowers, either directly from injectors connected to the blowers, or from diffusers used for aeration of the liquid in the tank. A bucket, weighed down by a counterbalance, receives air from injectors or diffusers below, and, as the air displaces liquid in the bucket, the buoyancy of the bucket increases until it exceeds the downward force of the counterweight, at which time the bucket pivots upward to release a large mixing bubble into the tank. An assembly for installation of the accumulator affixes the accumulator on a rigid vertical piece depending from a horizontal bridge.
