Elemental sulfur (S 0) is known to be an abundant, non-toxic material with a wide range of
redox states (-2 to+ 6) and may serve as an excellent electron carrier in wastewater …

Abstract Elemental sulfur (S 0)-based autotrophic denitrification (SAD) has gained intensive
attention in the treatment of secondary effluent for its low cost, high efficiency, and good …

Denitrification with non-organic electron donors for treating low C/N ratio wastewater has
attracted growing interests. Hydrogen, reduced sulfur compounds and ferrous ions are …

China has the largest textile production and export in the world, with a massive amount of
wastewater and related pollutants releasing. With an increasing concern to improve water …

The heterotrophic and autotrophic denitrification system can be used to remove wastewater
nitrogen effectively. However, the relationship between nitrogen removal performance and …

Raw biogas generated in the anaerobic digestion (AD) process contains several undesired
constituents such as H 2 S, CO 2, NH 3, siloxanes and VOCs. These gases affect the direct …

One of the major challenges in any sustainable aquaculture production systems is the
accumulation of nitrogenous waste such as ammonia and its biological nitrification products …

In this study, activated biochar (BC), nano zero-valent iron (nZVI) and biochar supported
nano zero-valent iron (BC-nZVI) were used to remove cathodic nitrate in bioelectrochemical …

Sulfur-based autotrophic denitrification (SAD) coupled with anammox is a promising process
for autotrophic nitrogen removal in view of the stable nitrite accumulation during SAD. In this …
