Abstract

Jet aerators have several inherent advantages that make them desirable for activated sludge systems. Recent developments in aeration technology and higher wastewater standards required by law have indicated the need for data that will permit rapid design and economic evaluation of aeration systems. For this purpose, data have been developed for jet aerators to determine the number of units required; associated pumps and compressors; installation method; and power required for operation. This paper discusses the history, data development, and method of application of jet aerators. Individual unit performance is presented as the basis for system design. System operation then is evaluated at variable load conditions to illustrate control and operating efficiency possible with jet aerators. Installation, maintenance, and expected life also are discussed.
