passive treatment systems are generally measured in their land use requirements. Passive treatment systems use con taminant removal processes that are slower than that of conventional treatment and thus require longer retention times and larger areas to achieve similar results. The goal of passive mine drainage treatment systems
are not untypical for mine wastewater/drainage applications, especially in coal mining or tailing effluents. Accordingly, the system needs to be flexible enough to cope with these varying conditions while consistently meeting defined effluent characteristics in the membrane permeate.
