Design of a Deflector for Water Aeration in Wastewater Treatment
Keyword(s):
The aeration phase within wastewater treatment is the most power consuming step required in the treatment of waste water. After the energy crisis in 1970s increasing attention has been paid for this step to reduce the energy cost [1]. Higher standard oxygen transfer efficiency (SOTE) reduces the amount of air required to aerate wastewater which reduce the air blower power consumption. In this study SOTE was investigated for the case of adding a bubble deflector, i.e. an external geometry that directs the bubbles toward the less oxygenated water, which improves the efficiency and eliminates the effect of dead zones in a rectangular water tank.
