Recycling Steel Manufacturing Wastewater Treatment Solid Wastes via In-process Separation with Dynamic Separators
Abstract
In steel manufacturing, various solid wastes are generated in wastewater treatment. Iron, carbon, and fluxes (CaO and MgO) are the main beneficial components in these solid wastes for recycling in the ironmaking and steelmaking process. However, the wastewater treatment solid wastes often also contain some undesirable components. Separation of those unwanted components from the wastewater treatment solid wastes is a prerequisite to recycle the solid wastes safely, economically, and environmentally. In this contribution, producing clean wastewater treatment solid wastes via dynamic separation at ArcelorMittal is reviewed and discussed, and some case studies are presented.
