| description | The increasing number of proposed technologies for the active treatment of acid mine drainage (AMD) raises a problem for decision-makers during the selection process. Selecting the optimum treatment technology requires extensive analysis to determine the best possible treatment based on multiple and often conflicting criteria. The introduction of multi-decision criteria analysis (MCDA) provides a systematic approach to problem-solving based on both quantitative and qualitative data. In this study, analytic hierarchy process (AHP) as an MCDA tool was used to select the optimum treatment option for AMD in a local copper mining site in the Philippines. Three treatment technologies were found to be the most applicable – a combination of Conventional Lime Neutralization and Sulfidogenic Bioreactor (CLN + SB), High-Density Sludge (HDS) Process, and a combination of Two-Step Neutralization Ferrite Formation and Sulfidogenic Bioreactor (TSNFF + SB). Three criteria – technical, economic, and environmental – and eight sub-criteria were used to evaluate and analyze the three alternatives systematically. The overall ranking of the alternatives was TSNFF + SB > HDS > CLN + SB. However, sensitivity analysis showed that HDS was the most stable treatment technology when equal weights were given for each criterion. Implications from this study could provide a more reliable information for possible technology adoption to sustainably address problems on AMD which is one of the leading global environmental problems today. |
