DuPont/Oberlin Microfiltration Technology. Applications Analysis Report.

摘要

The DuPont/Oberlin microfiltration technology demonstration was conducted under the SITE program at the Palmerton Zinc Superfund site in Palmerton, Pennsylvania, in April and May 1990. During the demonstration, the microfiltration system achieved zinc and total suspended solids (TSS) removal efficiencies of about 99.95 percent, and a filter cake solids content of 41 percent. The filter cake contained no free liquids, and a composite sample from all the demonstration runs passed both the extraction procedure toxicity characteristic leaching procedure (TCLP) test. The filtrate met applicable National Pollutant Discharge Elimination System permit limits for metals and TSS.
