Reduction of VOC emissions from aeration basins using mobil hoods and circulating aeration
- Univ. of Cincinnati, OH (United States); and others
As regulated under the Clean Air Act Amendments (CAAA) of 1990, Publicly Owned Treatment Works (POTWs) with large treatment capacities will be required to reduce their emissions of volatile organic hazardous air pollutants, primarily from the aeration basins. Previous studies indicate that circulating aeration may significantly reduce volatile organic compound (VOC) emissions, most of which are from the upstream portion of the aeration basin. Based on these findings, circulating aeration facilitated by partial tank covering using mobile hoods is proposed as an effective emission control strategy. Using this technology, less VOCs will be stripped into and concentrated in reduced amount of off-gases which can be efficiently treated by conventional control technologies. Compared with fixed rigid covers of aeration basins, mobile hoods are inexpensive to construct and easy to operate.
