反滲透 Reverse Osmosis
技術原理 Technical Principle
反滲透是利用反滲透膜的特性,通過施加超過滲透壓的壓力,溶劑(水)分子通過膜匯集成淡水,離子、有機物和膠體等雜質不能透過膜匯集成濃水,從而使水質凈化。 | 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. |
