Pilot-scale biological reactor systems were installed to treat metal-contaminated water in an underground coal mine and at a smelting residues dump in Pennsylvania. The reactors consisted of barrels and tanks filled with spent mushroom compost, within which bacterial sulfate reduction became established. Concentrations of Fe, Zn, Mn, Nni, and Cd were lowered by over 95 pct as these metals were precipitated in the reactors. The formation of insoluble metal sulfides by reaction with bacterially generated H2S was identified as an important metal-retaining process in the reactors. This paper examines the chemistry of the reactor systems and opportunities for enhancing their metal-retaining and alkalinity-generating potentials.
