Abstract

Sewage treatment plants are energy hogs. Among many, aeration systems account for 40-50 percent of the total energy use. To save energy, strengthening oxygen transfer characteristics is necessary. In order to do so, microscopic bubble-creating equipment is a prerequisite. This study focuses on microscopic bubble-producing air diffuser manufacture to save energy and enhance oxygen transfer.
