General Description:
The Simplex Aerator is a vertical shaft surface aerator which provides a mechanical means of oxygen transfer to sewage or industrial effluent. Manual or any required degree of automatic control can be provided including adjustment of aeration intensity by dissolved oxygen monitoring.

The Simplex Aerators can be mounted on conventional bridges, on tripods with light access bridges or floating. They can be mounted on configuration thereby offering a broad range of treatment capabilities from small communities to major installations.

Design:
Simplex Aerators provide sufficient oxygen input and maximum mixing characteristics with a minimum expenditure of power. The proven operating characteristics mean that the installations are simple, inexpensive and efficient.

Complete mixing and appropriate circulation velocities though the aeration tanks are achieved with the robust non-clog design.

Process:
Oxygenation of the fluid promotes the cultivation and reproduction of micro-organisms which carry out the treatment process by breaking down organic matter.

Oxygenation also re-establishes dissolved oxygen levels in the final effluent in order to sustain plant and animal life when discharged into rivers and lakes.

Vertical shaft aerators achieve oxygen transfer by developing a large interface between air and liquid so that oxygen can diffuse from the air into the liquid. In achieving this it is necessary to prevent local build up of oxygen concentration by promoting good mixing within the liquid.

The Simplex Aerator satisfies both these criteria by drawing up sub-surface liquid and discharging it in heavy torrents thus creating heavy turbulence upon striking the liquid surface with great force.

Technical Data:
We offer a standardised design of Simplex Aerators in the range of 4KW to 110KW. All aerators are guaranteed for the standard aeration efficiency into clean water (at 15 Deg. C) of 1.8Kg02/kW/hr (based on motor shaft power).

Splash protection can also be provided in the form of covers.
