WebTheoretically you can calculate Total Biological Oxygen Demand of any influent = 1.5 x BOD5 + 4.6 x TKN. While Carbonaceous BOD theoretically should require ~1.5 parts of O2 per part of BOD to be removed, nitrogenous BOD is significantly higher. For nitrogenous BOD the demand for oxygen is 4.6 lb O2/ lb BOD (4.6Kg/Kg) removed. To achieve ... Web• Air is only 21% (+/-) oxygen – Have to move a lot of air through water to transfer the oxygen – Oxygen readily dissolves into water • Passive – large footprint, low energy – Moving air over water allows for transfer • Mechanical – small footprint, much energy – Moving air through water for enhanced transfer
