Submersible Aerator
SUBMERSIBLE AERATOR
Features:
Submersible aerators
are frequently used in wastewater treatment plants, especially during
homogenization and equalization, preparing
stages, sludge stabilization and post-airing stages.
The aerator's submerged motor activates an impeller and the rotation of
the impeller result in vacuum to draw air from a special aspiration
chamber.
Water and air mix in the channel of aeration housing. The
air-water-mixture current is discharged speedily by the centrifugal force.
Power: 2- 75 HP, Oxygen input rate up to 85 kg o2/ hr.
1. High oxygen transfer rate due
to minor bubbles for wastewater treatment.
2. Oxygen transfer rate of unit BHP higher than other type of aerator.
3. Do not need to be emptied or the plant shut down for installation or
maintenance
