Description
Two granular sequencing batch reactors were operated for 160 days under anammox conditions, comparing the Anammox process and Sulfate Reduction Ammonium Oxidation process. The study aimed to investigate whether increasing the concentration of SO42- could enhance N removal rates under anaerobic conditions, and whether SO42- reduction and anammox processes are interrelated.
The second reactor, with an influent SO42- concentration increased to 952 mg S/L, exhibited higher rates of both ammonium and sulfate utilization compared to the first reactor, achieving a 2.1-fold and 15-fold increase, respectively. Nitrosomonas species were identified as the primary drivers of N metabolism, whereas Thauera species, responsible for S-dependent autotrophic denitrification, played a pivotal role in S metabolism.
This study suggests that synergizing the nitrogen-sulfur cycles could offer a sustainable and efficient approach for treating NH4+/SO42- rich wastewater.
