Hydrogen peroxide (h2o2) as a supplemental oxygen source the bod removal efficiency of aerobic biological treatment processes depends on a number of factors including (but not limited to): influent bod loading, f:m ratio, temperature, nutrient levels, and dissolved oxygen (do) concentrations.

The water demand component assesses the river basin water requirements for irrigation, and domestic, livestock, industrial and environmental sectors the crop water requirement is first estimated at the district level for the 12 crop categories and the other irrigated crops. Chemical oxygen demand is an important water quality parameter because, similar to bod, it provides an index to assess the effect discharged wastewater will have on the receiving environment higher cod levels mean a greater amount of oxidizable organic material in the sample, which will reduce dissolved oxygen (do) levels. Biochemical oxygen demand (bod) is a chemical procedure for determining how fast biological organisms use up oxygen in a body of water it is usually performed over a5-day period at20° celsius it is used in water quality management and assessment, ecology and environmental science.
