Abstract

Treatment of wastewater generated from petroleum exploration is essential to reduce pollutant levels and protect living organisms and the environment. Wastewater produced from the petroleum exploration process is called produced water. Produced water may account for up to 80% of total liquid production and cannot be discharged or reused directly because it contains pollutants such as total dissolved solids (TDS), iron (Fe), and barium (Ba). This study used activated carbon based on catalysts used for petroleum cracking containing Silica/alumina elements as adsorbents to reduce total dissolved solids (TDS) levels and harmful metal content such as Fe and barium. This study aims to determine the effect of variations in adsorbent mass (5, 10, 15, 20, 25 grams) and stirring time (30, 60, 90, 120, 150 minutes) on the decrease in TDS, Fe, and Ba metals. The optimal treatment condition was achieved using a 90-minute stirring period and 15 gram of activated carbon. Under these conditions, Fe and Ba decreased by 79.47% and 62.44%, respectively, and their final concentrations met the stated quality standards. The pH value remained within the acceptable range of 7.12 to 8.10. TDS decreased by 54.67% to 6,120 mg/L, but remained above the stated limit and therefore requires further polishing treatment.
