5 Simple Statements About chemical oxygen demand Explained

Measuring oxygen demand instead of TOC creates a clearer picture of how the acquiring waters will probably be influenced because of the organic and natural-made up of wastewaters. However, an empirical ratio amongst BOD, COD and TOC might be established and so, TOC analyzers can be practical for more rapidly analyzing one other two parameters to enhance drinking water treatment procedures.
