Successive Alkalinity Producing System (SAPS) is becoming popular worldwide for treatment of acid mine drainage (AMD). The effectiveness of SAPS depends upon many parameters such as hydraulic retention time (HRT), influent quality, characteristics of organic substrate and their design aspects. In this laboratory SAPS column study, four synthetic AMD solutions were treated for 1 day, 2 days, 4 days, 7 days and 10 days HRTs to determine the performances of SAPS using cow compost as organic substrate, saw dust and limestone in parallel in identical conditions. In this study, studies were carried out to find the effect of hydraulic retention time on iron, aluminum and manganese removal and alkalinity generation by laboratory SAPS. In this study, 100% iron and 100% aluminum and about 60% manganese removal has been found, particularly for 4 days HRTs and more depending upon metal concentration in influent AMD. Higher rate of alkalinity generation was observed in initial reaction period, then it got slower down after passage of time. The results of this study will be useful for design of SAPS for field operations and to improve performance of existing SAPS working in mines worldwide. © 2019, World Research Association.
