Upload NowIn this article we will discuss about the principle, requirements and procedure for determination of Chemical Oxygen Demand (COD) in water. Since there are more amounts of various chemically oxidisable organic substances entering water systems, BOD alone does not give a clear picture of organic matter content of water. Principle: A known volume of potassium […]

Detecting Coliform Bacteria in Water | Biotechnology
Article shared by :
Potable (drinking) water has great importance. Water is polluted by several waste materials and are responsible for infections like dysentry, typhoid, cholera etc. Analysis of water samples on a routine basis is not possible for each pathogen. Hence water is examined to detect Escherichia coli which indicates faecal contamination since this bacterium is always present […]
