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.
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

Effluent Treatment Mining operations with positive water balances face continuous challenges with increasingly stringent discharge regulations as well as highly variability in concentrations and flows of water to be treated.
Since 1989, the Mine Environment Neutral Drainage (MEND) program has worked to develop technologies to prevent and control acidic drainage. The program is directed by a multi-stakeholder committee, with members from the mining industry, federal and provincial governments, and non-government organizations.
