BOD Vs COD | What Is BOD | What Is COD

• COD measurements are usually made with samples of waste water or natural water, which are contaminated by domestic and industrial waste. • A closed water sample is incubated with a strong oxidizer such as potassium dichromate (K2Cr207) in combination with boiling sulfuric acid (H2SO4) at a specific temperature for a specified period of time.

COD is a defined test; the extent of sample oxidation can be affected by digestion time, reagent strength, and sample COD concentration. COD often is used as a measurement of pollutants in wastewater and natural waters. Other related analytical values are biochemical oxygen demand (BOD), total organic carbon (TOC), and total oxygen demand (TOD).

The competitive range for Evaporation would be 4-100 kg ,COD,/m 3, as indicated in figure 1.In addition, after 50 kg of ,COD,/m 3, when OHP is no longer able to operate due to an autothermal reaction, that would mean having to cool the reactor which could pose a risk.. Summary. There are different procedures for the treatment of refractory ,COD, in effluents that occur in certain types of industries.

Wastewater COD - Why it is Critical in Wastewater Treatment?

Wastewater COD, (,Chemical Oxygen Demand,) is the amount of oxygen necessary to oxidize the organic carbon completely to CO2 and H2O. Some organic chemicals are not completely oxidized. However, ,COD, is measured in approximately 3 hours via oxidation with potassium dichromate (K2Cr2O7) in the presence of Sulfuric ,Acid, and Silver Sulphate.
