We are very sorry for the confusion caused to the reviewers, the sentences have been revised from the words and Grammarly. The revised sentences are shown below: Ultrafiltration (UF) as an emerging alternative technology to conventional water treatment processes, has been widely used to remove pollutants such as particles, col-loids, bacteria, and viruses, thus reducing the risk of water-borne diseases [10]. However, in the case of the PPCPs with a small molecular weight (typically < 600 Da), UF membranes also cannot effectively reject these PPCPs, but nanofiltration and reverse osmosis are able to remove these PPCPs based on the thin-film composite [11, 12].
Point 15: Please add a comparative profile section to compare your results and prove how it better than previous.
