Abstract
Water circulation systems with air stripping arrangements to treat and remove undesirable disinfectant byproducts from potable water in municipal water tanks, ponds, and other bodies of water. The systems include a flotation platform, dish, draft tube, and an impeller to draw water from the depths of the tank up through the draft tube to be discharged outwardly of the dish to create a primary circulation pattern and an induced, inner or secondary circulation pattern. Each system additionally includes an air stripping arrangement positioned adjacent and about the upper portion of the draft tube and adjacent an upper portion of the secondary flow. The air stripping arrangement includes a plurality of submerged sets of air manifolds wherein pressurized air is supplied to the air manifolds and driven out of them in bubbles to create a treatment zone immediately above each set of manifolds.
