Question

Accepted Answer

BOD and COD are measurements used in STP plants to assess the organic pollution levels in wastewater.

BOD stands for Biochemical Oxygen Demand and measures the amount of dissolved oxygen required by microorganisms to break down organic matter in wastewater.
COD stands for Chemical Oxygen Demand and measures the amount of oxygen required to chemically oxidize organic and inorganic matter in wastewater.
Both BOD and COD are indicators of the organic pollution levels in wastewater and help in determining the treatment processes required in STP plants.
BOD is a measure of the biodegradable organic matter, while COD includes both biodegradable and non-biodegradable organic matter.
BOD and COD values are typically used to monitor the efficiency of the treatment process and ensure compliance with environmental regulations.
