The performance of SAPPS has been monitored intensively for 3years at the component level (influent, settling pond A, the successive alkalinity-producing system (SAPS), settling pond B, constructed wetland, and effluent). This study evaluated the ability of SAPPS to remove acidity and iron from influents at flow rates ranging from 17 to 160m3/day. The concentration of soluble Fetotal was the highest, and the pH was the lowest at low flow rates (≤61m3/day). When flow rates were over 80m3/day, concentrations decreased and Fetotal was removed primarily at the SAPS stage. For flow rates of less than 61m3/day, Fetotal was removed at the SAPS stage as well as in settling pond B and at the constructed wetland. Hydraulic retention times of 1 and 2days were found to be appropriate and economical for use with the SAPS stage and for settling pond B and the constructed wetland, respectively The treatment of acid mine drainage by conventional SAPPSs is limited by the availability of alkaline materials. However, the new proposed system can address this weakness through the provisioning of a suitable alkalinity supply.
