Thanks for the reviewer’s helpful suggestion. The objective statement has been added to the abstract to support the seriousness of the problem, and the revised sentences are as follows: Biological activated carbon (BAC) biofilter coupling ultrafiltration (UF) is a promising process for the treatment of river water contaminated by pharmaceutical and personal care products (PPCPs). However, the pilot-scale study should be conducted to reveal the long-term removal performance and the respective contributions of BAC and UF.
