Based on the reduction of sulfates to sulfides by anerobic bacterial metabolism of a biological carbon source (represented by the Biochemical Oxigen demand (BOD)) the amount of Sulfate reduced should be limited to the Biochenical oxigen demand of the carbon source. Equation: SO4 + CH4 = S + 2H2O + CO2. is the limit of sulfate redfuction simply a ration of the atomic weights of Sulfor and Oxigen? for example if BOD is 200 mg/l then limited amount of Sulfate reduction is 200 mg/l (96/64) or 300 mg/l
