Biochemical Oxygen Demand (BOD) Reduction
Biochemical Oxygen Demand is the amount of oxygen required in the oxidation of organic matter by biological action under specific standard test conditions. This is widely used to measure the amount of organic pollution in wastewater and streams.
Many companies are paying surcharges for BOD rather than trying to effectively remove them from the wastewater. Two types of BOD are present in wastewater-soluble and insoluble.
FAQ
Q. How do I remove BOD from wastewater to avoid paying surcharges?
A. First remove insoluble BOD through Clarification. The more efficient clarification (lower turbidity), the more insoluble BOD removed. Soluble BOD may then be removed by biological metabolism or commonly through oxidation via ozone, hydrogen peroxide, bleach, potassium permanganate, etc.
Q. Why does the oxidation of soluble BOD consume so much oxidizer.
A. Probably too many suspended solids in effluent water. More efficient clarification may reduce the demand for oxidizer.
