Floating Aerators
The floating aerator is an aeration device with floating arrangement such that the floating aerator move up and down with the level of the water in aeration tank. It has a float, a motor a draft tube, isolation piece and a directly coupled turbine type arrangement. The turbine draws water from lower tank level and splashes it from top, increasing the water surface area and water air contact time thereby increasing aeration efficiency.
