  陶氏反渗透膜BW60-1812-75作为纯物理脱盐薄膜分离技术,整个运行过程不添化学物质,所以没有相对变化。但根据膜结构机理及过滤原理等条件的限制,在整套水处理系统中为了控制微生物污染,所以要对进水采取预处理系统来保证东丽反渗透膜进水水质的合格,以及消除氧化性水对反渗透膜元件的氧化。

  陶氏反渗透膜BW60-1812-75工作原理

  对透过的物质具有选择性的薄膜称为半透膜,一般将只能透过溶剂而不能透过溶质的薄膜称之为理想半透膜。当把相同体积的稀溶液(例如淡水)和浓溶液(例如盐水)分别置于半透膜的两侧时,稀溶液中的溶剂将自然穿过半透膜而自发地向浓溶液一侧流动,这一现象称为渗透。当渗透达到平衡时,浓溶液侧的液面会比稀溶液的液面高出一定高度,即形成一个压差,此压差即为渗透压。渗透压的大小取决于溶液的固有性质,即与浓溶液的种类、浓度和温度有关而与半透膜的性质无关。若在浓溶液一侧施加一个大于渗透压的压力时,溶剂的流动方向将与原来的渗透方向相反,开始从浓溶液向稀溶液一侧流动,这一过程称为反渗透。
