Over 20 years of experience in the design of aerobic wastewater treatment plants have given wedotanks.comÂ® the know-how to design and construct the best precast concrete tanks and systems for both aerobic wastewater treatment plants and anaerobic wastewater treatment plants for nitrification/denitrification and biological Phosphorus removal.
Aerobic respiration (with oxygen) can produce 36 to 38 ATP molecules from each glucose molecule. 1  Anaerobic respiration (without oxygen) only allows glycolysis to continue which produces 2 ATP molecules from each glucose molecule. 2  Therefore, aerobic respiration is some 19 times as efficient as anaerobic respiration.
