Abstract
The wastewater generated from coal mining activities if not handled properly will become a major source of environmental pollution for either water resources or aquatic species and humans. Metal elements released by wastewater into the environment cause water pollution, thus adversely impacting biodiversity. The purpose of this study is to identify and describe the potential for liquid waste pollution from coal mining activities and methods for treating polluted water in coal mining in the Tisihu coal field. From this research, we can conclude that choosing the Active Treatment Technologies for wastewater method is the right method for coal mining sites in Tisihu. The built wastewater treatment plant (WWTP) comprises four compartments; wherein Compartment I the process of coagulation with fast stirring took place, in Compartment II there was a process of flocculation with slow stirring, the process of sedimentation took place in Compartment III, whereas the last process in Compartment IV was in the form of a neutralization process using lime. The effectiveness of Coal Mine Wastewater Treatment shows a very effective reduction in TSS, Fe, and Mn parameters above 80%.
