Iron sulphides, mainly in the form of mackinawite (FeS), pyrrhotite (Fe 1-x S, x= 0–0.125) and
pyrite (FeS 2), are the most abundant sulphide minerals and can be oxidized under anoxic …

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 …

Biological denitrification process in mainstream wastewater treatment often needs dosing
supplemental electrons, consequently adding a remarkable operating cost. Organic carbon …

Anaerobic ammonium oxidizing (anammox) bacteria based technologies are widely applied
for nitrogen removal from warm (25–40° C) wastewater with high ammonium concentrations …

A bstra ct High concentration nitrogen-containing organic wastewater is a potential substrate
for hydrogen production by dark fermentation. In this study, the effect of initial pH on the …

In recent years, iron mediated autotrophic denitrification has been a concern because it
overcomes the absence of organic carbon and has been successfully used in denitrification …

In rural domestic wastewater treatment using subsurface constructed wetland system
(SFCWs), the lack of a carbon source for denitrification and limited phosphorus uptake are …

Sulfide prevails in both industrial and municipal waste streams and is one of the most
troublesome issues with waste handling. Various technologies and strategies have been …

Chemolithoautotrophic denitrifying microorganisms oxidize reduced inorganic sulfur
compounds coupled to the reduction of nitrate as an electron acceptor. These denitrifiers …

This study investigated the impacts of thiosulfate (S 2 O 3 2−) as well as chemically
synthesized and biogenic elemental sulfur (S 0) on the rates of sulfur-based denitrification in …
