A Radial aerators are equipment composed of a submersible motor, with impeller for aeration and agitation in sewage systems. They are a very flexible, versatile aeration system when the mixing of a fluid with air supply is required.
Working principle:
An air cavity is, with the help of the offset, generated, from which air is entrained by emulsification into the water flow.
1. The radial submerged aerator system is frequently used in waste water treatment plants, especially during homogenisation and equalisation, pre- aeration stages, biological oxidation plants, sludge stabilisation and post aeration processes.
2. Also can be used in Equalization tank, Sequential batch reactor treatment plant, Aerobic digester, Homogenization tank and Ideal for cleaning of storm tanks.
3. Mainly used for feeding water pre-treatment and sewage bio-chemical treatment process like, aeration grit chamber, ‘pre aeration tank, air floatation tank, stirring, etc.
4. Iso can be used in aquaculture pond to add oxygen and landscape water conservation.
1. This water/air mixture is compressed into the expulsion channels, which are designed to increase the contact time between air and water and maximise working area. As the unit is placed on the base of the tank or chamber it provides comprehensive mixing as well as aeration. This means the likelihood of dead zones are minimised in your application.
2. Used in balance tanks to mix effluent while the addition of oxygen helps
prevent septicity.
Impeller – SS 304 Shaft SS 420
Mech. Seal – Silicon Carbide
Aeration – Galvanized Steel
1. Extremely simple installation, even in a flooded tank
2. Ideal for mixing combined with aeration of waste water containing sewage, organic industrial effluent, slurry, etc.,
3. No need for compressed air supply as it is self-aspirating
4. Can supply oxygen for aeration in breakdown or overload circumstances
5. Low noise level compared to surface – systems
6. No aerosol effect
7. Can be used where water levels vary 8. Special structures such as bridges, not needed
