陶氏反渗透膜RO-3838/30-FF基本原理
当纯水和盐水被理想半透膜隔开,理想半透膜只允许水通过而阻止盐通过,此时膜纯水侧的水会自发地通过半透膜流入盐水一侧,这种现象称为渗透,若在膜的盐水侧施加压力,那么水的自发流动将受到抑制而减慢,当施加的压力达到某一数值时,水通过膜的净流量等于零,这个压力称为渗透压力,当施加在膜盐水侧的压力大于渗透压力时,水的流向就会逆转,此时,盐水中的水将流入纯水侧,上述现象就是水的反渗透(RO)处理的基本原理。
陶氏反渗透膜RO-3838/30-FF使用注意事项
1、在安装前,保持密封包装,干燥阴凉处保存,避免曝晒并防冻。
2、安装时,选用适当润滑剂,以甘油为最佳。
3、新系统运行时,要彻底冲洗,将保护液及溶剂冲干净。
4、运行1小时后,记录各运行参数,48小时后再记录各运行参数,对比两者之间的变化。
