- •
The reactor treated wastewater at sulfate concentrations up to 1980 mg L−1.
- •
COD and sulfate removal efficiencies were above 100% at COD/Sulfate ratios equal to or higher than 2.6.
- •
The reactor presented high performance during 888 days of operation.
- •
Biomass discharge or washout did not occur thus indicating very low biomass production under the conditions assayed.
- •
Organic matter removal and sulfate reduction were not impaired by the reactor operation interruption for 200 days.
