The sustainable development goals (SDGs) established by the United Nations aim to ensure access to clean water and sanitation for all. One way to improve the quality of drinking water is by using a natural substance made up of environmental elements. Therefore, it was necessary to maintain the degree of alkalinity of the water, starting from 7 pH level. While previous studies have focused on raising the pH levels of water by adding alkaline compounds, recent research has suggested using baking soda, which has a pH of approximately 9. However, there are several unfavorable health effects associated with adding baking soda to water, including hypokalemia, hypochloremia, high blood salt levels, deterioration of kidney illness, deterioration of heart failure. In this study, a substance made from silica using the thermal fusion method has been developed by the authors. This substance raises the pH of water without the need for additional components, using a physical field of 80 cm. The outcomes of the study demonstrated the efficiency of this natural chemical in improving water quality. Using a natural silica physical field to raise the pH level of water is a safe and effective method without the need for additional components that can have unfavorable health effects. The results recommended that water at 7 degrees is completely pure distilled water suitable for drinking in normal ways and indicated that alkaline water with a pH between 8.5 and 10 degrees is beneficial for people suffering from irritable bowel syndrome. Moreover, improving drinking water quality is essential for achieving the SDGs, specifically SDG 6, which aims to ensure access to clean water and sanitation for all. By utilizing natural methods to improve water quality, we can work toward achieving a more sustainable and equitable future.
