Wastewater Plants around the world have varying loading characteristics and technologies, and many employ the biological nitrification process to convert ammonia to a less toxic form in wastewater. The nitrification process requires oxygen that is provided by large blowers or aeration mixers. The oxygen is transferred to the water and provides an electron acceptor for the biochemical reaction that converts ammonia to nitrate. In an ever changing world challenged with the rise of energy costs, there has been a push to develop technologies that offer energy efficiency and reduced operating costs. Aeration is typically the largest energy consumer, requiring 40-60% of the plant’s total electric demand charge. However, there are ways to reduce the growing demand:
