**5.1 Determine whether the pH values**

To determine whether the pH values were successfully increased, the following evaluation criteria were implemented:


The results shown in **Figure 5** indicate a clear and significant effect of the material extracted from silica in raising the pH levels of water. The data presented in the *Improving the Quality of Drinking Water by Raising the pH Levels Using a Natural Na2SiO3… DOI: http://dx.doi.org/10.5772/intechopen.112856*

**Figure 5.** *The results of the pH value over time (Trial 1).*

**Figure 5** demonstrate a consistent increase in pH levels over time, indicating that the substance has a long-lasting effect on the pH of water. The effectiveness of the extracted material in raising the pH levels can be attributed to the natural silica physical field created by passing water through layers of silica-rich. This physical field is believed to alter the ionization state of the water, resulting in an increase in the concentration of hydroxide ions, and hence, a rise in the pH levels. The findings of this study are particularly significant for water treatment applications, as they demonstrate the potential of natural silica physical fields to increase the pH levels of water, thereby making it safer for human consumption. The use of natural silica physical fields could provide a more sustainable and cost-effective alternative to traditional water treatment methods that involve the use of chemicals and artificial pH stabilizers.

To ensure the accuracy and validity of the results, the tests were repeated under the same conditions as the first experiment in the laboratories of the Drinking Water and Wastewater Authority in Egypt after a 2-week interval. The results of the second experiment confirmed that the pH levels increased when the substance was used in a natural silica physical field, as depicted in **Figure 6**. The repetition of the experiment under the same conditions helped to confirm the reliability of the initial results and validate the effectiveness of the natural silica physical field in raising the pH of water.

The results presented in **Figures 5** and **6** provide promising evidence of the potential of the material extracted from silica to raise the pH levels of water. Further research in this area could lead to the development of more sustainable and costeffective water treatment methods that leverage the unique properties of silica to improve the quality and safety of our water resources. These results agree with recent scientific studies that have confirmed the effectiveness of natural silica physical fields in raising the pH levels of water [17]. These studies have shown that the dissolved silica in water can form complexes with metal ions, resulting in the precipitation of metal hydroxides. This process results in the removal of heavy metals and other impurities from water and the increase in the pH levels [18].

### **5.2 Radiation test**

Radiation testing is a process used to detect, measure, and evaluate the levels of ionizing radiation in a particular material or environment. **Table 2** summarizes the evaluation method and procedures used to determine whether the manufactured material (Silica SiO2) contains radioactive or nonradioactive elements. The goal of this evaluation was to ensure that the material was safe for human use and did not pose a risk of radiation exposure. The evaluation process involved several steps, including sample preparation, measurement of radioactivity, and analysis of the results. The samples were prepared by grinding the material into a fine powder and then placing it in a sealed container to prevent contamination. The radioactivity of the samples was measured using a gamma spectrometer, which is a device that can detect and measure gamma radiation emitted by radioactive isotopes. The gamma spectrometer was calibrated using a set of standard reference materials before the measurements were taken. The results of the radioactivity measurements were then analyzed to determine whether any radioactive isotopes were present in the material. If radioactive isotopes were detected, their concentrations were calculated and compared to the limits set by international safety standards to determine whether the material was safe for human use.

Based on the previous results, it is evident that Na2SiO3 can effectively raise the pH levels of water, and it was safe according to the radiation test results in **Table 2**. These findings are consistent with the conclusions of Du et al. [19], who demonstrated that precipitated silica could be produced using Na2SiO3 as a precursor and HCl as a precipitant under specific conditions. What sets our study apart from previous research is that we were able to raise the pH of the water using a natural silica physical field without any direct chemical interference with the water. This approach is unique because it helps to protect the water from any potential chemical effects that may arise from other pH-raising methods [20]. Our findings suggest that natural silica physical fields have significant potential for pH control and water treatment applications. The use of natural silica physical fields offers a more sustainable and environmentally friendly alternative to traditional chemical-based methods for pH control.

#### **6. Conclusion**

The use of natural silica physical fields for pH control and water treatment has gained increasing attention in recent years due to its potential for a more sustainable and cost-effective alternative to traditional chemical-based methods. The unique properties of silica, such as its high surface area, charge density, and porosity, make it an ideal material for water treatment applications. The objective of the current research was to investigate a natural substance derived from environmental elements. This substance, which was extracted from silica using the thermal fusion method, was developed by the authors to enhance the pH level of water with an 80 cm physical field. Notably, no additional components were added to the water during the experimentation process. The study included both laboratory experiments and field tests. In the laboratory, water samples were placed in containers and exposed to the natural silica physical field for a set amount of time. In the field, the natural silica physical field was created by placing the water source near layers of silica-rich. The results of our study provide further evidence of the potential of natural silica physical fields for pH control and water treatment. The unique approach taken in this study demonstrates the effectiveness of this method for raising the pH levels of water without any direct chemical interference. These findings have important implications for the development of more sustainable and environmentally friendly water treatment methods.
