scope:

The methods described under these standard guidelines, which were first developed by ASCE (1996), provide several proven techniques for measuring oxygen transfer under process conditions. Nonsteady-state, off-gas, and inert gas tracer methods are described in Chapters 2, 3, and 4. Chapter 5 is a brief comparison among methods. The methods presented are considered to be well developed and provide satisfactory precision for a wide range of aeration processes in suspended-growth biological systems.

Because a wide range of process variables and wastewater characteristics that affect the precision (and accuracy) of these methods are difficult to control, the methods are offered as standard guidelines and are not recommended for compliance testing of aeration equipment. These guidelines use both the Système International (SI) units and common units. Symbols and nomenclature are defined in Appendix E. ASCE (1996) can still be obtained from the American Society of Civil Engineers in Reston, VA.
