Abstract

The objective of this study is to explore the efficiency of carbon granules, magnesium oxide, and alum powder in the process of water purification. This study analyzed the pH, clarity, and Odor of the water from both soap water and pond water to evaluate the impact of methods on soap water and pond water. Although the pH was increased and the processing time was extended, it was shown that magnesium oxide is an effective method to reduce turbidity, especially in pond water. The alum powder proved successful in limited capacity for cleaning soap water and pond water with considerable pollution load when applied to badly contaminated water. This was because it was not able to properly cleanse soap water and pond water. The employment of carbon granules with the process of filtering was of importance for the necessary pH values to be reached during the post-treatment phase. Magnesium oxide and carbon granules generally exhibited good results in some applications; however, the efficiency of alum powder was found to be limited under the conditions tested in the study.
