Title: The electrolytic respirometer—I factors affecting oxygen uptake measurements
Abstract: The electrolytic respirometer provides a more accurate and more complete measurement of biochemical oxygen demand (BOD) of wastewaters samples than normally is obtained by the standard dilution BOD method. Laboratory and field studies have shown that the electrolytic respirometer is a dependable instrument for making BOD measurements, is simple to operate, and provides a continuous readout of the oxygen uptake reaction. The major factors affecting oxygen uptake measurements with the electrolytic respirometer are the mixing rate and the concentration of oxygen demanding material in the sample. These system limitations can be overcome by using simple procedures such as increased mixing rate or enrichment of the oxygen in the air in contact with the sample. The precision of BOD measurement with the electrolytic respirometer was considerably greater than with the dilution method.
