Abstract
Water is essential for human survival; however, access to safe water remains a global challenge. The use of natural-based coagulants in the Municipality of Talaingod has been limited. Thus, this study was conducted to evaluate the potential of Moringa seed powder as an organic coagulant for wastewater treatment, serving as an alternative to commercially available aluminum sulfate. The study employed a Completely Randomized Design (CRD) with 18 water samples, each subjected to three replications per treatment. The treatments included T1 (Untreated), T2 (2.5 g MSP), T3 (5 g MSP), T4 (7.5 g MSP), T5 (10 g MSP), and T6 (2.5 g Alum). The physicochemical parameters assessed in this study were pH level, total dissolved solids (TDS), and electrical conductivity (EC). Statistical analyses using Levene’s test, Welch’s ANOVA, and standard ANOVA confirmed significant differences across treatment groups for all three parameters (p < 0.01). Moringa treatments (2.5–5 g/500 mL) maintained pH levels comparable to untreated water, while higher doses (7.5–10 g/500 mL) caused a decrease. Alum treatment significantly reduced pH. TDS increased notably with both Moringa and alum treatments, with alum exhibiting the highest value (565.33 mg/L). Similarly, EC followed a comparable trend, with alum dramatically increasing conductivity (1189 µS/cm), whereas higher Moringa doses reduced EC. These findings suggest that Moringa seed powder provides a more stable treatment in terms of water chemistry, whereas aluminum sulfate induces more substantial physicochemical changes.
