REDUCTION OF SULFATE CONCENTRATION IN COAL MINING WATER USING BATCH ELECTROCOAGULATION WITH ALUMINUM ELECTRODES
This study investigates the efficacy of the electrocoagulation process using aluminum electrodes for reducing the initial sulfate concentration of 2239 mg/l in coal mining water. Variables such as current intensity (0.5, 1, and 2 amperes) and contact time (15, 30, and 45 minutes) were examined. T...

| 總結: | This study investigates the efficacy of the electrocoagulation process using
aluminum electrodes for reducing the initial sulfate concentration of 2239 mg/l in
coal mining water. Variables such as current intensity (0.5, 1, and 2 amperes) and
contact time (15, 30, and 45 minutes) were examined. The highest removal
efficiency of 50% was achieved at 2 amperes and 45 minutes, which also increased
the pH from 3.25 to 10.125. This process demonstrated a decrease in electrical
conductivity and Total Dissolved Solids (TDS), indicating a reduction in ionic
content and dissolved solids. The findings confirm that increasing current intensity
and contact time enhances sulfate removal efficiency through the formation of
Al(OH)3 coagulants, underscoring the importance of optimizing electrocoagulation
parameters for effective coal mining water treatment.
