APPARATUS FOR AERATING LIQUIDS IN A TANK HAVING WAVE ATTENUATOR

摘要

A surface aerator in a tank creates horizontally directed surface flow that forms waves as the flow progresses through the tank and impinges upon the tank wall. At least one substantially horizontal baffle is mounted adjacent the inner wall of the tank adjacent or subjacent the liquid level and is positioned at a point of high wave amplitude to attenuate the waves by eliminating the vertical energy component thereof. The baffle may have a passage therethrough for circulation of liquid.
