Abstract
A new method for carbon addition was developed in a batch denitrification system by feeding methanol through a silicon tube. The methanol then diffuses across the membrane to the other side where the biofilm is formed. The results show that the residual COD could be controlled to less than 50 mg/L during the denitrification period with denitrification rates higher than 4,500 mg NO3 --N/M2·d. Once the denitrification is completed, the COD breakthrough occurs. The advantages and disadvantages of this system are discussed.
