Abstract

This chapter introduces the technical background and water quality improvement principles of water-lifting aeration, and describes the methods of designing and optimizing the structure of a water-lifting aerator. The mixing and oxygenation performance of a water-lifting aerator is analyzed using established mathematical models of hydrodynamics and oxygen transfer for the aeration chamber of a water-lifting aerator. Application conditions for controlling the internal water quality pollution and algal blooms by using water-lifting aeration technology are analyzed and discussed. With the help of the computational fluid dynamics (CFD) method, the flow fields outside a water-lifting aerator are numerically simulated, and the effective radius of the algae inhibition zone analyzed and determined. The proper installation height and outflow configuration of a water-lifting aerator are also numerically analyzed and optimized.
