The economical operation of a wastewater treatment plant depends largely on the design and the interplay of the aeration and process controls. Moreover, the human factor and the management objectives are at the heart of the plant’s reality and should also be taken into consideration. Selection and thoughtful integration of all the subsystems is of paramount importance.
The intent of this paper is to provide information that will help the engineer appropriately define both the design and the evaluation criteria of various blower technologies. The real total costs of ownership over time should guide the selection process.
