Water treatment to obtain clean water that meets the quality requirements based on the regulation of the Health Minister of the Republic of Indonesia No. 492 of 2010, with an electrolysis process. The process that occurs is by separating elements H2 and O2 from H2O compounds, from the results of the separation of the two elements of water, resulting in electrolytes that have changed the pH of water and TDS required for clean water. Electrolysis methods are used by conducting experiments in two separate containers filled with electrolytes. Electrolytes in containers are treated with a 15 volt electrical voltage with a time variation. Each time interval for giving an electric voltage affects the change in pH. Changes in pH in all three water samples occur because of an increase of hydrogen gas (H +) in the water during the electrolysis process, in the electrolysis process bubbles of hydrogen and oxygen gas are formed in the Anode and Cathode. Giving electric current to water electrolytes, undergoes TDS changes. This means that there is an effect of the voltage on the TDS changes so that the water becomes clean and healthy. Changes that occur on TDS values from 3 samples for two sample anode containers show that the TDS value has decreased and one sample has increased TDS value. But the findings of the TDS values obtained from the research from these three samples showed that the TDS values were still permitted for clean water health requirements.
