逆滲透薄膜系統分離組件回收率及參數優化組合之研究

隨著社會發展，化學毒物無聲充斥於生活周遭，也深深影響著我們的健康。尤其水更是人體每日必需品，因此重視水質安全是健康生活最重要的第一步。在水資源汙染日益嚴重下，各式淨水產品也相當多，其中逆滲透RO純水系統在生飲水設備中扮演重要的角色。然而在淨化過程中，目前逆滲透RO系統回收率均以原廠建議值為設計概念，耗水、耗能是對逆滲透飲用水設備最深刻且呆板的印象，因此如何改變既有的窠臼，讓回收率及產品優化組合可以達到最佳功效，具有研究探討的空間。本研究以最好最佳水資源利用為目標，並回顧分析過去文獻、以田口品質工程實驗方法作為實驗基礎，利用直交表的因子水準排列進行試驗。執行過程中，首先找出四個可控制參數及各參數之二個不同水準來配置八組實驗模型,並模擬系統於一年週期運轉時數進行實驗測試，再將實驗數據利用統計分析運用，以S.N.比來轉換反應值作為品質特性，進而獲得具體優化最佳參數。研究結果顯示，將逆滲透薄膜系統供應電壓、馬達流量、限流閥及原水供應壓力依據最優化組合設計之產水效率較以往增加11%，回收率也由15%提升至28.9%，一共節省13.9%水資源，相較於5年以上之產品週期壽命，將可獲得提升整體效能124.5%以上之經濟利益。

With the rapid development of society, chemical toxicants are flooded with our lives around and affect our health deeply. Particularly, water is daily essential element to human body, so water safety is the most important first step for healthy life. Water pollution is becoming more and more serious day by day, all sorts of water purifier are congested with our life, among them, reverse osmosis system is playing an important role for the fresh water. However, in the process of purification, the recovery rate of reverse osmosis system takes original suggestion value for the design conception; most people stereotype to think the reverse osmosis system with the problem of water consumption and power consumption, how can we change the existing concept to promote the recovery rate and optimize products for achieving the best efficiency still have the room to discuss and probe. This research proposal puts the optimum water resources utilizing for the objective and literature review, taking Taguchi Methods for the basic of experiment; using the factorial level array of the Orthogonal Array for the experiment. In the process of the experiment, firstly, pick 4 controllable parameters and 2 different level of each parameter to configure 8 groups experimental model, and imitate the system with running hours for one year period experiment, then compile statistics and analyze the data, taking S.N to transfer the reaction value as the quality property to obtain the specific optimum parameters. The research result shows the production efficiency increasing 11% than before , when taking the design from the reverse osmosis membrane system supply voltage, the pump flow , the restricted flow valve and raw water pressure which according to the optimization group ; the recovery rate increases from 15% to 28.9% , it saves in all 13.9% water resources , in comparison to more than 5 years product life cycle , it can obtain 124.5% economic benefit.
