The performance of three BAFs with zeolite, activated carbon and anthracite media for the treatment of polluted Huaihe raw water were investigated. All three BAFs performed promising permanganate index (CODMn) and ammonia nitrogen (NH4+-N) removal efficiency as well as the turbidity removal was over 60%. Moreover, the CODMn and NH4+-N removal in the three BAFs were affacted by the characteristics of filter media. Activated carbon and anthracite had better CODMn removal than zeolite. Zeolite had the best NH4+-N removal, followed by activated carbon, anthracite was the worst.
