Results demonstrated that moderate NaClO pre\u2010oxidation effectively avoided the risk of flocculant oxidation while enhancing algal and turbidity removal by approximately 6% and 18% after DAF, respectively. About 12\u2009mg\/L polyaluminum chloride (PAC) and 15\u2009mg\/L FeCl\n                    <jats:sub>3<\/jats:sub>\n                    showed optimal algae removal performance, but PAC had a better coagulation effect on DAF than FeCl\n                    <jats:sub>3<\/jats:sub>\n                    , which was 26.8% higher than FeCl\n                    <jats:sub>3<\/jats:sub>\n                    . Low\u2010dose cationic polyacrylamide (PAM) could further enhance flocculation. The SF unit after DAF served as a key physical barrier, elevating overall algae removal to &gt;\u200995% and achieving 100% turbidity removal under the optimal dosing process (0.5\u2009mg\/L NaClO + 12\u2009mg\/L PAC\u2009+\u20090.2\u2009mg\/L PAM). This study provided a technically feasible emergency strategy for seawater desalination pretreatment against HABs shocks, ensuring water supply security.\n                  <\/jats:p>","DOI":"10.1002\/wer.70498","type":"journal-article","created":{"date-parts":[[2026,7,18]],"date-time":"2026-07-18T08:40:17Z","timestamp":1784364017000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Dissolved Air Flotation on Algae Removal in Seawater Desalination Pretreatment During Harmful Algal Blooms"],"prefix":"10.1002","volume":"98","author":[{"given":"Xunzhou","family":"Li","sequence":"first","affiliation":[{"name":"Sunrui Marine Environment Engineering Co.
