ABSTRACT:
A wastewater aeration system that can be pivoted upwardly to expose the treatment basin floor for removal of accumulated grit or other solids. The aeration system includes a blower and a rigid or flexible supply conduit extending into the basin to supply lateral pipes with air. The laterals normally extend horizontally along the basin floor and carry air diffusers which discharge air into the basin. A winch and cable system or other mechanism can be operated to pivot the lateral pipes and diffusers upwardly away from the basin floor so that they are out of the way of equipment used to remove grit from the floor. A vertical track may be provided along a wall of the basin to accommodate raising of the lateral pipes and diffusers out of the basin.
