Removal Sulfur, Ash Coal Processing

Industrial Wastewater Treatment for Coal Ash Pond Remediation

Coal Pile Runoff. Pile runoff basins have historically been used for the removal of suspended solids (coal fines) prior to discharge to wastewater streams. However, it was soon found that other contaminants were in this waste stream. Sulfur compounds contained in coal were oxidized by rainwater and produced sulfuric acid.
