- Abstract:
- A combined process of ozone/ceramic membrane and activated carbon was applied to treat the source water from Beijiang River. The control effect of the integrated equipment on turbidity, chroma, CODMn, ammonia nitrogen and nitrite nitrogen as well as non-conventional indicators such as emerging contaminants was investigated, and the mitigation effect of ozone on ceramic membrane fouling was explored. The combined process could be directly applied to treat the source water. When the dosage of ozone and PAC was 3 mg/L and 15 mg/L, respectively, the turbidity, chroma, CODMn and ammonia nitrogen removal efficiencies of the combined process were 99.8%, 100%, 72.9% and 100%, respectively. No coliform group was detected in the effluent from the combined process, indicating that the combined process could effectively kill the bacteria. In addition, 19 detected PPCPs and 5 detected EDCs removal efficiencies of the combined process were approximately 82.2% and 92.8%, respectively. The membrane fouling model showed that cake layer clogging was the main form of membrane fouling in ceramic membrane filtration of the source water.
