COD – Chemical Oxygen Demand

Chemical Oxygen Demand (COD) measures the amount of oxygen required to chemically oxidize organic and inorganic substances in water. It is a key indicator of wastewater strength and pollution potential.

  • CPCB Limit (Discharge to surface water): <250 mg/L
  • CPCB Limit (Discharge to land for irrigation): <100 mg/L

High COD levels deplete oxygen in receiving water bodies, leading to aquatic life damage and poor water quality. Regular monitoring ensures efficient treatment and environmental compliance.
