Chinese Abstract

目標:將電解水生成器視為一個「淨水單元」,探討一般飲用水經電解水生成器電解後之水質變化。方法:以市售某廠牌電解水生成器為對象,以純水添加微生物或無機鹽類作為人工合成進流水,在不同電解條件下進行測試,探討所生成電解水的水質特性。結果:進流水通過電解糟後,水體的pH值、氧化還原位(ORP)及電導即發生顯著之變化,同時酸性水及鹼性水之水質特性趨勢亦相反。測試結果顯示電解水生成器可去除部分砷及鉛,對總菌落數及大腸桿菌群也有部分去除效果;但使用純水為進流水之試驗結果顯示生成之電解水水質並無明顯變化。結論:經電解作用所生成電解水水質成分。但進流水水質隨地理環境及使用原水之不同而有所不同,必須注意如何控制電解質之添加劑以維持電解功能之充分發揮。

English Abstract

Objective: An electrolyzed-water treatment device was used as a ”water purification unit” to evaluate the changes on the characteristics of drinking water quality after electrolysis. Methods: The characteristics of the electrolyzed water were studied using a commercial electrolyzed-water treatment device. Laboratory spiked water with various compositions of inorganic and microbial was used as the input water. Water quality parameters before and after different electrolysis conditions were compared. Results: After electrolysis, major differences were observed on the pH, oxidation-reduction potential (ORP) and conductivity between the electrolyzed water and the input water. An opposite trend was observed between the electrolyzed acidic and alkaline water. The electrolysis process was able to remove part of lead and arsenic, partial removal was also obtained for coliform groups and total bacteria counts. However, no apparent change was observed after electrolysis when pure water was used as the input. Conclusion: The change in pH, ORP and conductivity in electrolyzed water was due to the presence of the electrolytes in water. In some cases it is necessary to add some electrolytes in input water to enhance the electrolysis processes. However, since the input water quality varies with geographic locations, one should carefully control the amounts of the electrolytes in input water for the optimum performance of the electrolysis process.
