LITTLE STIRRER
Cage Rotor Aerator for use in oxidation ponds.
Introduction
The use of cage rotor Aerators is rapidly gaining wide acceptance as an efficient and economical method of treating effluent that is discharged into oxidation ponds. These Aerators are quiet running and give speedy assistance to a naturally occurring biological process.
Tests carried out have shown our Cage Rotor Aerator to have a clearly superior oxygen transfer rate and greater mixing ability than that of Aspirator type Aerators, and is more efficient than the high speed splasher type machines.
Operation and Action
The ability to keep the top third of an oxidation pond mixed and aerobic is critical to its successful management. The Cage Rotor supplements the natural process by bringing the bacteria into contact with the sewage and keeping the top layer aerobic and mixed. This process prevents dead spots in the pond and in turn prevents odours, midges and eliminates public nuisance.
Through aeration from the top of the pond, the possibility of dragging sludge up from the bottom is minimised. As a result any possible imbalance in bacteria production is also minimised. Sludge built up on the bottom of the pond should be dredged and disposed of as a separate operation.
Design Features
The rotor comprises of eight helical paddle arms mounted on the tips of four star shaped end plates. The rotor is mounted to the pontoons via self-aligning bearings, which are fully welded. The rotor is driven by a shaft mounted, geared motor. A walkway between the pontoons allows for easy access from one side of the machine to the other. All steel components are hot dipped galvanised to protect against corrosion. All major components are quickly and easily unbolted allowing for ease of transport. Current range comprises 1.1kw, 2.2kw, 4kw, 8kw and 11kw.
