The Climb To The Top

Back in the late 1980’s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators. As production plants got away from in-ground basins, one of the more simple innate operational checks became more challenging; that being the view of the aeration basin water surface. For years, a plant operator could simply look at the basin from across a parking lot or out a window and see the surface aeration pattern and be able to do the “eyeball check.”
