Vertical shaft, slow speed aerators are ideal for the bacterial oxidisation of effluent by the transfer of oxygen from the atmosphere and to provide the necessary turbulence to maintain homogenisation and mixing between the live medium, the polluting elements and the water thus oxygenated. Oxygen transfer rates are proportional to the power absorbed at the aerator shaft and this, in turn, is governed by the size, speed, and immersion of the turbine.
