Two Are Better Than One: Advantages of Dual Point Control in Centrifugal Aeration Blowers
Abstract:The wastewater industry's answer to the design and procurement of single-stage centrifugal blowers and aeration process automation.
Studies conclude the aeration process in an activated sludge wastewater treatment plant consumes 40 to 60 percent of a plant's power usage. With the dramatic impact of the aeration process on the overall operational expenses of a plant, the last three decades has seen increased focus on the design, implementation, and operation of high efficiency single-stage centrifugal blowers and aeration control systems. State and local agencies offer a variety of funding options that favor energy-minded aeration systems due to the increased global emphasis on energy conservation.
This paper will discuss the different types of high efficiency single-stage centrifugal blowers used in wastewater treatment plants, along with blower and aeration system control methodologies to maximize the overall aeration process efficiency.
In addition, this paper will detail two case studies where alternative funding options allowed the implementation of high efficiency single-stage centrifugal blowers and aeration control systems, which yielded significant energy and operational savings.
