Each individual of those oxidants is utilized to determine COD in differing kinds of drinking water: CODMn (COD Manganese) is utilized in determinations for slightly contaminated bodies of drinking water. In contrast, CODCr (COD Chrome) is Employed in determinations of heavily contaminated water or wastewater a result of the substantial oxidizing electrical power of the reagent [fifty two, 62].
This can help improve the overall environmental effectiveness of industries and reduce their influence on h2o means.
If wastewater containing superior COD stages is discharged right into a natural overall body of water, the natural contaminants may perhaps consume or react with dissolved oxygen leading to dangerously lower amounts of oxygen, generally known as hypoxia. This affliction can tension or outright get rid of aquatic existence.
