Changes in the Biochemical Oxygen Demand Procedure in the 21st Edition of Standard Methods for the Examination of Water and Wastewater
|
ABSTRACT:
The dilution biochemical oxygen demand (BOD) test has widespread application for design and operation of wastewater treatment processes, evaluating the quality of natural waters, and assessing the effect of wastewater discharges on these waters. While standardization of the BOD-measuring method has become of prime importance in maintaining dependable data acquisition, changes are made as needed in response to questions raised by analysts and to accommodate new applications.
