【摘要】 该文介绍了超滤技术,分析了超滤技术应用于海水淡化预处理的技术优势,考察了超滤系统在反渗透海水淡化预处理工程中的运行情况.实验采用50 ku和10 ku聚砜中空纤维膜组件,讨论了超滤膜孔径、操作压力、过滤时间对预处理出水浊度、COD(Cr)和膜过滤通量的影响,分析了超滤系统出水污染指数(SDI)随时间的变化情况.更多还原

【Abstract】 Ultrafiltration techniques are introduced in this paper.Advantages of ultrafiltration applied in the pretreatment of seawater are analyzed.During pilot testing,influence of different MWCO ultrafiltration membrane,operation pressure and filtration time on the removal of turbidity,COD(Cr) and filtration flux is investigated using 50 ku and 10 ku polysulfone hollow fiber UF membrane. SDI of UF filtration was measured against time to evaluate performance of pretreatment systems.更多还原
