SAPS' INFLUENT AND EFFLUENT GEOCHEMICAL PARAMETERS RELATED TO AMD POLLUTION CONTROL: A CASE STUDY

This paper presents a time-series study on the geochemical parameters of a Successive Alkalinity Producing System (SAPS) in an abandoned mine of South Korea. Two new performance parameters in terms of ratio are proposed: Feinfluent : Feeffluent and Sulfateinfluent : Sulfateeffluent. The ratios directly point to the state of performance of SAPS. After the 6 year study, iron reduction still remains acceptable but sulfate reduction becomes negligible.
