A COD Digester is a specialized laboratory device used for determining the Chemical Oxygen Demand of water and wastewater samples. It is an essential instrument for evaluating organic pollution and ensuring effective wastewater treatment processes.
Understanding Chemical Oxygen Demand
Chemical Oxygen Demand (COD) represents the amount of oxygen required to oxidize organic and inorganic matter present in water. Higher COD values indicate increased pollution levels, making COD analysis a key parameter in water quality assessment.
How a COD Digester Works
The COD Digester heats sealed digestion tubes containing the sample and chemical reagents at a constant high temperature. This controlled heating ensures complete oxidation of pollutants, allowing accurate COD measurement after digestion.
