Testing of Sewage, Nitrogen, Chlorides, Hydrogen Sulphide, Organic Carbon, Dissolved Oxygen, Grease and Fats, Chemical Oxygen Demand

Testing of Sewage

	Testing of Sewage Sewage is most commonly tested for: total solids nitrogen chlorides hydrogen sulphide organic carbon dissolved oxygen grease and fats chemical oxygen demand biological oxygen demand
These tests are important to analyse the strength of sewage and to what extent, it can harm the environment. Presence of chemicals in sewage indicate the various treatment nature of the sewage (whether the sewage is fresh or is it decomposed anaerobically or whether it contains lot of organic matter, etc.)
