Scope

This document describes the microbial coulometric method for determining the biochemical oxygen demand in water.
This document is applicable to the determination of biochemical oxygen demand in surface water, groundwater, domestic wastewater, and industrial wastewater. Water samples that are toxic to microorganisms are not suitable for this determination method.
The detection limit of this method is 0.5 mg/L, the lower limit of determination is 2 mg/L, and the upper limit of determination for undiluted water samples is 500 mg/L. If the concentration exceeds this upper limit, the samples should be diluted before determination.
