Abstract
The report gives results of an evaluation of the effectiveness of two treatment alternatives in achieving best available technology (BAT) standards: (1) direct filtration, using a dual media filter; and (2) hydroxide precipitation with lime, followed by dual media filtration. With the promulgation of Best Available Technology Economically Achievable Effluent Guidelines and Standards for Iron and Steel Manufacturing, a greater degree of treatment than the clarification process normally used to achieve best practicable technology (BPT) standards may be required for sintering plant blowdown. Evaluation of a third alternative, alkaline chlorination, was attempted; but, due to nonrepresentative test conditions, the effort was abandoned. Based on the limited data generated during the study, it appears that either treatment alternative tested would produce an effluent that would meet the promulgated BAT standards. Direct filtration is less expensive and requires less maintenance and operator attention than the hydroxide precipitation/filtration alternative. The treatment processes were tested, using two EPA-owned mobile pilot plant trailers: one contained a clarifier, used to simulate preclarification; and the other contained the hydroxide precipitation clarifier, chemical tanks, dual media filter, and associated equipment.
