H2o Top quality Evaluation: COD measurement is often a important Resource for assessing the overall air pollution amount and natural and organic content of h2o. High COD values reveal the existence of major quantities of natural and organic pollutants, such as wastewater, industrial effluents, or natural chemicals. Checking COD will help in assessing the drinking water high quality and determining sources of air pollution.
Inspite of some issues, COD stays a valuable Instrument for checking and managing the treatment processes in a very wastewater remedy plant and guaranteeing compliance with environmental rules.
