Pilot Plant Treatment of Acid Mine Drainage by Reverse Osmosis

摘要

Studies were conducted at the EPA Crown Mine Drainage Control Field Site (a) to examine the performance of a 227,000 lpd (60,000 gpd) reverse osmosis (RO) unit at recovery levels of 50 percent through 90 percent for a variety of dominantly ferrous iron acid mine drainage (AMD) feed qualities, (b) to evaluate the feasibility of using the neutrolosis process to treat AMD, and (c) to determine the AMD treatment capability of a coupled 18.9 1pm (5 gpm) sodium cycle cation exchange (CIX)/RO system.
