As a country with high rainfall (average 2,900 mm/a in 2021), Indonesia has serious problems with the quantity and quality of coal mining wastewater. By adopting an open pit mining system, wastewater can reach a discharge of 2000 L/s at its worst, with the main quality problem being high turbidity caused by colloidal clays/suspended solids. The tot...

Coal mine water contains high concentrations of suspended solids due to clay minerals carried away by surface runoff. Removing it becomes problematic since it requires chemicals, especially in large catchment areas in mining sites. Due to this, Total Suspended Solid (TSS) concentration in coal mining water can reach up to 5,400 mg/L. In Indonesia,...
