Vertical Shaft Aeration

Vertical shaft, slow speed aerators are ideal for the bacterial oxidisation of effluent via the transfer of oxygen from the atmosphere. The aerators provide the necessary turbulence in order to maintain homogenisation and mixing between the live medium, the polluting elements and the water thus resulting in oxygenated sludge. 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. In addition to a fixed installment, the vertical shafts can be positioned on floating pontoons.
