The Waste Acid Detoxification and Reclamation (WADR) process combines selective precipitation and vacuum distillation to remove heavy metals and recycle acids from spent acid streams. Now at the pilot-scale stage, the transportable system includes a flash separator, vacuum column, and support equipment to separate out the acids and heavy metals{endash}leaving a clean water stream that can be reused or sent to sewer. Simulated spent acid wastes can be tested to determine potential waste volume reductions and acid recoveries. Preliminary testing can be performed in a laboratory-scale system with large-scale demonstration testing to follow if desired or necessary. 5 refs., 3 figs.
