Description:
This technology assessment addresses design and evaluation of fine bubble aeration equipment. It discusses the associated gas transfer theory used as the basis for measuring water and wastewater oxygenation efficiency. Mixing requirements are also discussed. While bubble aeration is not new technology, increasing power costs and the potential for relatively high oxygen transfer efficiency has generated renewed interest in the performance of fine bubble wastewater aeration equipment. The many interrelated variables affecting measurement and efficiency of fine bubble aeration systems are identified and discussed. Comparison with other aeration methods is made, and an estimate of the potential national impact of fine bubble aeration on wastewater treatment energy savings is presented. Research and development efforts which are needed to improve fine bubble aerator performance are identified. This report evaluates fine bubble aeration technology and discusses its development status. The report is liberally referenced so the reader can obtain specific details if desired.
