How is bod related to water quality
WebThe standard 5-day biochemical oxygen demand (BOD 5) measurement of water quality is used widely as a design parameter for water resource recovery facilities (WRRFs).This measure usually includes a component of nitrogenous oxygen demand (NOD) that can cause oversizing of biological processes and under-evaluation of process capacity. WebBiological oxygen demand (BOD5) or chemical oxygen demand (COD) analysis is widely used to evaluate organic pollutants in water systems as well as the efficiency of …

Web23 nov. 2024 · The objective of water quality monitoring is to obtain quantitative information on the physical, chemical, and biological characteristics of water via statistical sampling (Sanders et al. 1987). The type of information sought depends on the objectives of the monitoring programme. Most natural waters contain small quantities of organic compounds. Aquatic microorganisms have evolved to use some of these compounds as food. Microorganisms living in oxygenated waters use dissolved oxygen to oxidatively degrade the organic compounds, releasing energy which is used for growth and reproduction. Populations of these microorganisms tend to increase in proport…
