Ability of Zeolite and Cassava Peel to Improving Iron (Fe) and pH in Drilled Well Water

The amount of Fe in groundwater is usually quite high and causes the water to turn yellow-brown color. According preliminary test results, levels were 4.62 mg/L pH was 4.3 one drilled wells Banjarbaru, which did not fulfill quality criteria. Using zeolit cassava peel enhance can be taken as an option. aim this study determine effectiveness combination zeolite improving a well. An experiment with post-test only control group design used for study. research population entire supply from Banjarbaru’s wells. sample well water, part testing. Kruskal-Wallis employed analyze differences levels, followed by Mann Whitney p-value < 0.05, indicating that there significant difference after treatment combinations A, B, C. study’s findings, C most effective increasing up 0.91 (78.32%) 7.2.
