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...

Aeration is one of the important processes employed in activated sludge process of the biological treatment units of wastewater. In this process the level of dissolved oxygen in the effluent is raised to the required amounts to decompose organic matters present in the effluent and thereby to reduce the BOD (biochemical oxygen demand) of the effluent by a physical means called aeration process . The aeration process consumes as much as 60-80% of total power requirements of wastewater treatment plants. Therefore, the efficiency in design of aeration process is required so that wastewater...
