Aquaculture engineering - design of gas transfer systems for aquaculture, part 2

摘要

This is the second of a three-part series on the design of gas transfer systems for aquaculture. Part 1 discussed site and water-supply considerations. Part 2 will discuss the rating of aerators under standard and field conditions. Standardized rating procedures have been developed in the wastewater treatment field. These rating procedures can be used to compare different types of aerators, but can not be used directly for design because the rating conditions are quite different from the operation conditions in aquaculture applications. However, the performance of gas transfer for aquaculture applications can be estimated from the standardized ratings. For some types of gravity aerators, alternative performance parameters may be more appropriate. Part 3 of this article will explore the design and selection of aerators.
