The concentration of CODCr in the SMBR was 449.3mg/ℓ-CODCr, and the concentration of permeate water was 100.3mg/ℓ-CODCr. The removal efficiency was about 70.1%. The amount of ozone required for the removal of the fluorescent whitening agent in the permeated water in SMBR was 6.67g-O3/min, and the amount of ozone required to remove CODMn relative to the permeate water was calculated to remove 0.997mg-CODMn for 1mg of O3.
