Biological sulfate removal in an upflow packed-bed reactor
Technical Report

OSTI ID:5734871
A biological process for the removal of sulfate, using molasses as organic carbon source, is described. Sulfate is converted to sulfur via sulfide, and molasses to bicarbonate. The process is accompanied by the precipitation of calcium carbonate and heavy-metal sulfides. Sulfate reduction follows zero-order kinetics with respect to both reactants and products. The reduction of 1 g sulfate consumes 1,2 ml molasses and requires 6 h for completion. The Darcian minimum upflow velocity for sulfate reduction in an anaerobic packed-bed reactor was found to be 1,3 m/h and the optimum temperature 31 C.
