中文摘要 | 本文以微孔性聚□薄膜為支撐體與磺酸化聚□-聚乙烯醇為皮層製成複合式薄膜 ,並在不同壓力與溫度的操作條件下,探討氯化鈉水溶液在此薄膜中之滲透效果,以瞭解 膨潤性薄膜對氯化鈉水溶液之分離特性,實驗結果發現,水流通率隨操作壓力增加而增加 ,但存在非線性關係,而除鹽率亦隨操作壓力增加而增加且呈非線性關係,針對此實驗結 果,本研究利用四種不同溶液擴散模式分別加以解析,求得相關質傳係數並討論其適用性 。 |
英文摘要 | The composite membrane was formed with microporous polysulfone film as a support and sulfonated polysulfone-polyvinyl alcohol as a skin layer in this study. The characteristics of the diffusivity of a NaCI solution in this swelling composite membrane were studied under various operating pressures and temperatures. It was found that the water flux and salt rejection increased with an increase of the operating pressure. However, their correlation existed in a non-linear relationship. According to these results, four different methods of solution-diffusion model analysis were compared for the case of NACI solution transport through a sulfonated polysulfone-polyvinyl alcohol/polysulfone composite reverse osmosis membrane under various operating pressure and temperature, which were discussed and evaluated as the respective transport parameters. |
