This article describes the wastewater treatment systems developed by Cleveland Electric for the efficient, reliable treatment of coal pile runoff. The process employed uses a step-wise rather than the single stage neutralization technique for pH adjustment. Also, solid/liquid separation is accomplished in compact high-rate clarifiers and thickeners. Lime is added as a slurry rather than the more conventional dry feed, assuring rapid dissemination of lime in the reaction tank. The systems have met or exceeded all requirements and produced an effluent with a pH in the range of 6 to 9 and total suspended solids in the range of 20 mg per liter. The design of a coal pile runoff treatment system is described in depth.
