反渗透 Reverse Osmosis
技术原理 Technical Principle
反渗透是利用反渗透膜的特性,通过施加超过渗透压的压力,溶剂(水)分子通过膜汇集成淡水,离子、有机物和胶体等杂质不能透过膜汇集成浓水,从而使水质净化。 | Reverse osmosis (RO) means to force solvent(water) molecules to pass RO membrane while ions, organism and colloid fail to pass it by exerting a pressure over the osmotic pressure depending on the characteristics of the RO membrane, the former shall get together to form fresh water and the latter to form concentrated water, thus purifying the water quality. |
