The performance of passive biochemical reactors in ,acid mine, drainage (AMD) treatment could be enhanced by using fine organic substrates in new reactor designs, such as diffusive exchange reactors. This work evaluated the effect of fine cellulosic components in organic mixtures and of enrichment with inoculum, on sulfate and metals removal in discontinuous cultures for three types of synthetic AMD.

ACID MINE DRAINAGE TREATMENT AND METAL REMOVAL …

Acid mine, drainage (AMD) is a dangerous form of pollution characterized by high acidity (pH near 2-3) and substantial quantities of sulfate and soluble metals (Fe, Zn, Cu, Ni, Pb, and Cd ions). The accumulation of sulfate in sediments and aquatic systems causes the release of toxic sulfides that can damage the environment ( Utgikar et al., 2002 ; Ghigliazza et al., 2000 ).

This ,acid mine drainage, (AMD) is generated when metal sulfide minerals, mainly pyrite, are oxidized in the presence of water and accelerated by the action of chemolithotrophic bacteria. This generates acidity and mobilizes large concentrations of iron (Fe), and other toxic trace metals and metalloids, depending on the composition of the exposed rock ( Robb, 1994 ; Mason, 2002 ).
