Evaluation of the Proposed Y-12 Steam Plant Wastewater Treatment System

摘要

A wastewater treatment facility has been conceptually designed to treat the Y-12 steam plant and ancillary effluents to meet the Clean Water Act's Best Available Technology limitations. This report presents the results of a program to acquire representative samples of the major effluents to be treated in this facility, to characterize these samples, and to perform a bench-scale evaluation of the conceptual design flowsheet. Results indicate the wastewater can be successfully treated with Ca(OH) sub 2 to remove all pollutants, except copper, silver, and TSS to levels specified in the probable Limits for Y-12 Process Waste Discharges to East Fork Popular Creek. Flocculation of the sludge produced by the Ca(OH) sub 2 coagulation with PURIFLOC A23 reduces sludge volume by approx. 69%. Results also indicate that vacuum filtration is a better alternative than centrifugation for dewatering the sludge. 16 references, 10 figures, 7 tables. (ERA citation 10:003355)
