It serves like a key indicator of drinking water high quality and delivers beneficial insights into the level of natural and organic pollutants present in aquatic environments.
Examine wastewater samples for BOD testing residual chlorine Until it might be shown which the check here sample was gathered previous to where chlorine is added.
Chlorine is a strong oxidizing agent and it can inhibit the microbial advancement through wastewater BOD Investigation, so it should be faraway from sample in advance of commence the analysis. Chlorine is usually taken off by including the sodium sulfite towards the sample in next method.
Those sample dilutions meeting these conditions should produce probably the most legitimate results. These criteria are as follows:
