Todays, tap water was supplied for people’s daily life which is regenerated after special purification process for safety and cleanliness. The purification process was composed very complex steps, i.e. precipitation, neutralization, sterilization and deodorization etc., in a water treatment plant after gathering by catchment area. Although the water gathered at same catchment area, it should be represent different physicochemical properties with it has been treated at different process. In this study, we investigated the reasons why tap waters gathered from different regions have different properties. And analyze component of tap water to have different properties using cyclic voltammetry, pH meter and ORP meter as an electrochemical analysis. |
