COMPREHENSIVE STUDIES OF SURFACE AERATION SYSTEMS

Oxygen transfer rate and the corresponding power requirement to rotate the rotor are very vital parameters for the design and scale-up of surface aerators. Basically two types of operation are in use for surface aeration systems ¿ batch operation and continuous operation.The work presented in this book consists of two parts. The first one deals with the experimental investigations on the three types of batch surface aeration tanks. A comprehensive design analysis has been worked out and presented on these types of surface aeration systems. In the second category, experimental investigations have been carried out extensively on continuous flow surface aeration systems of different sizes. Analysis has led to the formulation of optimal geometric dimension and the simulation criteria for the design purposes.
