Abstract
"An industry that participated in an energy efficiency program initially installed a fine bubble aeration system in one of its smaller aeration tanks. The industry thought this was the best approach to try the fine bubble change in equipment in a small tank and if it proved to be energy efficient they may consider it in their other tanks.. The modification proved to be very beneficial to the industry because the summer after it was installed they increased the organic load to be treated by approximately 30 percent. The installed fine bubble system treated more than 50% of the facility’s influent. This performance exceeded forecasted expectations and provided real performance data to support additional modifications.
The industry has moved forward to convert two additional small tanks to fine bubble aeration. The conversion will provide the facility with the option to operate only its three small aeration tanks to treat all of its wastewater. The paper will provide the details of the initial energy efficient recommendation to convert all of the aeration tanks. Further it will present the development of how the plan was modified to address staging the improvements. The industry is presently consuming the same amount of energy as it was originally, however, it is treating 30% more organic load with the industry continuing to increase its production. Therefore for this location a modification to equipment is allowing them to control their energy consumption and eliminate the need to construct additional treatment tanks."
