Abstract
Biological wastewater treatment of wastewater is performed by oxidizing organic carbon with sulfur or a sulfur compound as an electron carrier, and reducing the sulfur or sulfur compound to sulfide. The sulfide is oxidized with nitrate or oxygen. If necessary, ammonia is oxidized to nitrate and then reduced to nitrogen gas. The process is effective for saline waste water facilities, as well as non-saline waste water facilities.
