Low Speed Surface Aerators
Low speed aerators are used in waste water treatment plants to replace oxygen consumed by the biological material. The impeller churns the liquid surface and sprays water radially outwards at high velocity to maximise the mass transfer. The unique impeller design draws liquid from the depths of the basin to provide full mixing throughout the basin.
These aerators are typically used in large treatment works where the a typical water depth of 4 m - 6 m.
These aerators consist of a motor, gearbox, coupling, shaft, impeller and baseplate. The baseplate height is adjustable to provide precise impeller submergence levels to achieve maximum oxygen mass transfer.
The Zentec low speed aerator is ideal for municipal and industrial wastewater treatment facilities aiming to enhance treatment efficiency and reduce operational costs.
