- Manufacturers of diffused aeration systems claim that converting from coarse bubble to fine bubble system should yield a 50 percent energy cost savings.
- Fine bubble diffused aeration is able to maximize the surface area of the bubbles and thus transfer more oxygen to the water per bubble.
- The plant was used in 1952 to test diffused aeration technology and a diffused-air activated sludge purification system has been in continuous use since.
- Surface aerators are commonly quoted as having an aeration efficiency of 0.5-1.5 kg O 2 / kWh, diffused aeration as 1.5-2.5 kg O 2 / KWh.
