This demonstrated that the scaled-up system was capable of reducing the total selenium (of which most was selenate) in the FGD wastewater from over 2500 ppb to below 10 ppb and total mercury from overwastewater prior to treatment provided the combined wastewater stream is treated to the new effluent limit standards for FGD wastewater prior to discharge. The combined stream will be subject to the numerical discharge limits for arsenic,
