Biochemical oxygen demand (BOD) is the amount of oxygen required by aerobic microorganisms to decompose the organic matter in water, such as sewage. You many also hear it referred to as biological oxygen demand. What does this mean as it relates to your communities wastewater treat plant? Simply put, a big portion of waste sent to a treat facility is protein, fat, vitamins and carbohydrates. In addition to waste food, bad bacteria, viruses and other not so nice things are discharged. We also eliminate a certain amount natural “good” bacteria. Over the years as our understanding of “good” microorganisms has increased, we have found ways to harness their potential for advancing society.
At ClearCove we know BOD is critical to all microorganisms. What we do differently is preserve the food source in wastewater for the anaerobic bacteria. So instead of trying to reduce organic loading using aerobic techniques, we mechanically remove it. The result, a more effective food supply for acidogenesis, acetogenesis & methanogenesis bacteria resulting in greater methane or biogas production.
