5 In an activated sludge wastewater treatment plant, COD is removed aerobically by heterotrophic bacteria. The treatment plant has the following characteristics given in Table Q5. Table Q5 (a) Using Monod kinetics, calculate the bacterial growth rate and COD removal rate at winter with the average temperature of 10C, assuming that the DO is the limiting factor. 5 In an activated sludge wastewater treatment plant, COD is removed aerobically by heterotrophic bacteria.
