Energy is the second largest expense in most water resource recovery facilities. In an activated sludge plant, for example, more than half of total energy consumption goes to the aeration blowers.Operators looking to reduce energy costs naturally look at the blowers. Many blower-related energy conservation measures are available, including:Advanced process control to match airflow to demand
Supplementing existing blowers with new right-sized blowers
Replacing existing blowers with new high-efficiency modelsThese measures are often supported by electric utility incentive programs that pay customers to reduce their bills. A typical incentive covers up to half of project costs, including equipment, installation and engineering. The
