GE <\/span><\/span>是世界上**將三層復合膜技術應用于反滲透膜和納濾膜上的公司。三層膜結構主要應用在反滲透膜和納濾膜上，通過在膜元件的聚酰胺薄膜層<\/span>(PA) <\/span><\/span>和聚砜層<\/span> (PS) <\/span><\/span>層之間插入<\/span>GE <\/span><\/span>公司**性的薄膜層<\/span> (<\/span><\/span>見圖<\/span>2<\/span><\/span>—<\/span>1 <\/span><\/span>所示<\/span>)<\/span><\/span>，從而使膜表層更加光滑減少了污染物在膜表層的沉積，提高了膜元件的抗污染能力，減少了膜系統對預處理的要求。<\/span><\/span><\/p>
