| Abstract | Source stream characterizations and bench/pilot treatability studies were performed on waste water from an integrated coal washery/by-product coking operation at an iron and steel plant. Major parameters of interest were phenolics, cyanide, ammonia, and suspended solids. The feasible treatment schemes identified among nine procedures tested were: biological activated sludge and carbon adsorption (for phenolics and cyanide); steam stripping/acid adsorption (for ammonia); and neutralization/polyelectrolyte addition/centrifugation (for coal suspensions). In addition, a new full-scale design for the coal preparation plant was produced. Portions of this document are not fully legible. |
