摘要:	隨著半導體及TFT-LCD等高科技產業的發展，在製程上需求高潔淨的水以移除表面汙染物是極重要的步驟，在尺寸極大化與製程技術提昇的產業趨勢下，產業用水成本伴隨需求而激增，因此水資源之有效運用是目前極需重視的課題。本研究針對超純水系統之離子交換處理單元的產水所需消耗的藥劑成本進行探討，研究方法以課題達成型QC STORY的流程步驟為主軸，發展一個可以解決課題的方案流程，並以U公司的超純水系統為實例進行驗證，在確保品質安全範圍下使產水之藥劑成本得以改善，進而達到節能減廢的成效，其核心步驟如下: 在課題明確化的階段，選用適當的QC工具加以分析選定1.採水終點時間之決定及2.再生加藥條件之調整此兩項目作為課題研究的掌握項目。在方案擬定及追究階段，以腦力激盪的方法展開方案，然後對方案進行實驗規劃及試作驗證評估，並排定施作的順序。在最適策的實施階段，對離子交換處理單元進行實驗測試，依實驗的紀錄資料進行迴歸分析以建立合理的採水週期設定模型，作為對應不同自來水入水水質條件的操作依據。 With the development in the high-tech industry such as semiconductor and TFT-LCD industry, using highly pure water to remove the surface pollutant is a very important procedure. In the trend of size maximization and the production skill improvement, the cost of the industry water is increasing sharply. Therefore, to use water effectively is an issue needed highly attention. The research is focus on the regenerate solution cost to produce water in Ion-exchange resin of ultra pure water system. The research method is using the procedure of achieving task QC STORY, as the main shaft to develop a process to solve the subject. Taking U Company’s ultra pure water system for example to verify, the regenerate solution cost could be down under quality and safety control so that the resource could be saved and waste could be less. The core steps are as follow: In the task clarification stage, it is to select the suitable QC tools to analyze and then get the 2 main findings in the research: deciding the endpoint of the ion exchange system, adjusting the chemical dosing condition for regeneration. In the plan and investigate stage, First, it is to develop the plan by brainstorm methods. And then it is to experiment the plan and have test run to verify the plan. According to the result, the execution priority list could be made. In the most suitable implementation stage, it is to experiment and test the ion exchange resin. And using regression analysis, according to the experiment record, to establish reasonable resin service cycle time hypothesis model as the operation basis dealing with different piped water quality.
