If wastewater that contains large COD amounts is discharged right into a purely natural human body of water, the natural and organic contaminants may well take in or respond with dissolved oxygen resulting in dangerously very low amounts of oxygen, often called hypoxia. This problem can worry or outright kill aquatic lifestyle.
The COD test is really a beneficial evaluate of effluent top quality of the wastewater cure plant. It provides a quick, approximate evaluate of all chemically oxidizable substances and can be used to establish performance difficulties in therapy services.
