Owing to the characteristics of the marine environment, seawater desalination systems of offshore islands in tropical areas will absorb more impurities, which often results in premature aging of the reverse osmosis membrane of the seawater filtering desalination system, such as air scrubbing tank and ultrafiltration equipment. This article proposes a design scheme of a prefiltering seawater clarification system. Experiments show that the filtering system can effectively reduce the operating burden of follow-up equipment and improve the efficiency of desalination equipment. It is suitable for popularizing this technology in similar islands.
