  陶氏反渗透膜TW30-1812-36工作原理

  反渗透又称逆渗透,一种以压力差为推动力,从溶液中分离出溶剂的膜分离操作。对膜一侧的料液施加压力,当压力超过它的渗透压时,溶剂会逆着自然渗透的方向作反向渗透。从而在膜的低压侧得到透过的溶剂,即渗透液。高压侧得到浓缩的溶液,即浓缩液。若用反渗透处理海水,在膜的低压侧得到淡水,在高压侧得到卤水。

  陶氏反渗透膜TW30-1812-36具有高渗透性,能去除大量对人体有害的物质,比如:致癌物质,重金属物质以及饮用水中的细菌和病毒。其过滤精度为0.0001um超微小的孔径。利用超静压力泵高压渗透,使水分子和离子态的矿物质元素,通过一层逆渗透膜,而溶解在水中的绝大部分重金属、有机物以及细菌、病毒等,则无法透过逆渗透膜被截留。

  DOW FILMTEC reverse osmosis (RO) membranes for home drinking water treatment units are the most reliable and consistent elements in the industry. Advanced membrane technology and automated fabrication allow Dow to precisely produce each and every element to tight, pre-defined specifications. Dow’s advanced and consistent RO element quality helps customers deliver systems that reliably provide low impurity drinking water. DOW FILMTEC elements are shipped dry for convenient handling and long shelf-life.
