ABSTRACT:
A single port venturi device is provided for aeration of wastewaters containing suspended solids. The device has a non-obstructive design which prevents attachment or accumulation of suspended solids, and promotes even air distribution for efficient aspiration of air and mixing of air and wastewater. The device has provisions for adjustment of the venturi throat size, for protection of the throat from wearing out, for enhancing air and wastewater mixing capabilities, and for flushing of the solids accumulated in the air entrance.
