Abstract
The supply of oxygen for aeration is the single largest energy consumer at activated sludge wastewater treatment plants, representing 50–90% of total plant energy requirements (1,2). Replacement of less-efficient aeration systems with fine pore aeration devices can save up to 50% of aeration energy costs and has resulted in typical simple payback periods of 2–6 yr (3). As a result of these very impressive cost savings, a very large number, 1000–2000 municipal and industrial wastewater treatment facilities in the United States and Canada now use fine pore aeration.
