Evaluation of Energy Consumption Efficiency of an Air Diffuser in a Sewage Treatment Aeration Tank Under Standard Conditions

Abstract

In 1970s, the Korean government formulated an energy saving plan, and in 1990s, they added items while implementing the efficiency rating and labeling system. According to the data released by the International Energy Agency (IEA), by 2050, energy savings by the equipment and facilities sector would account for 36% of the policy measures for greenhouse gas reduction. As such, the most useful way to reduce greenhouse gas emissions is to increase the original energy efficiency by distributing various energy-saving products through the efficiency management system. High-efficiency energy equipment certification is a system that certifies products that meet a certain standard in order to promote the supply of high-efficiency energy equipment. In the case of aeration devices, the performance and efficiency of air diffusers can be continuously managed to reduce national energy and carbon dioxide emissions. The purpose of this study is to confirm the definitive carbon reduction levels in the relevant field by examining the performance-based appropriate energy efficiency of air diffusers in aeration tanks during sewage treatment.
