The Effect of Activated Carbon and Coagulants from Papaya Seeds in Improving the Water Quality of Well Water PT X

Abstract

Solid waste from papaya seeds which contains a water content of 7,29% and ash content of 7,55% has the potential to be processed into coagulants and activated carbon. Well water at PT X has high levels of turbidity, pH and COD. This study aims to compare the effectiveness of activated carbon and coagulant from papaya seeds in improving the well water quality of PT X, based on the parameters of pH, TSS, TDS, Turbidity, and COD. Doses of coagulant and activated carbon were used (1, 2, 3) grams and contact time (48 and 60) minutes respectively. The research showed that activated carbon at the dose of 1 gram, contact time 60 minutes was able to reduce TSS 97,08%, TDS 72%, Turbidity 89,68%, and COD 54%. While the coagulant dose of 1 gram, contact time 60 minutes can reduce TSS 88,39%, TDS 64%, Turbidity 72,45% and COD 80%. The percentage decrease in TSS, TDS, Turbidity and COD values in the use of activated carbon from was more effective to reduce pollutant levels of well water at PT X.
