BOD is calculated in sewage procedure or wastewater remedy to find the destruction of natural and organic wastes by aerobic microbes
Should the sample DO is greater than saturation place in the event the bottles are positioned during the incubator, oxygen will physically move away from Option and seem like an oxygen demand from customers. The ensuing BOD will probably be falsely large.
Should the sample isn't diluted, the Organic action on the microorganisms will expend the DO from the BOD bottle prior to the five day incubation time is up. If the ultimate DO is simply too small, the BOD cannot be established. There's no technique for understanding at what stage in the 5 days the DO reached zero.
