 15kW Simplex Aerators in operation at Bury WwTW, United Utilities |
Key Features: • Power ratings from 3kW to 200kW. • Slow speed, range is 40 to 60 rpm. • Complete mixing • (SAE) into clean water 1.8 kgO2/kWhr • Upto 4.0m diameter • Bridge mounted or floating |
| 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 Surface Aerators are available for conventional bridge mounting, on tripods with light access bridges, in simple rectangular tanks or channels, or floating. Simplex Surface Aerators can be installed in any configuration within aeration lanes thereby offering a broad range of treatment capabilities from small communities to major installations. Design: Biwater Simplex Aerator provides 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 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: Biwater Treatment offer a standard design of Simplex Aerators in the range of 3KW to 200KW. All aerators are guaranteed for the standard aeration efficiency (SAE) 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 GRP or steel covers. Full scale test conditions can be simulated for
the majority of aerators at Biwater’s purpose built research
test facility, which has an adjustable volume of up to 2250m³
and a maximum power input of around 100kW.
