Autotrophic denitrification (AuDen) is an efficient, convenient and eco-friendly biological
process for the treatment of nitrate-contaminated organic-deficient waters. AuDen can be …

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 …

Autotrophic denitrification under acidic conditions using sulfide (S 2−), elemental sulfur (S 0),
and thiosulfate (S 2 O 3 2−) as electron donors are evaluated. Results from batch and …

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

This study was carried out to determine the possibility of autotrophic denitritation using
thiosulfate as an electron donor, compare the kinetics of autotrophic denitrification and …

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 …

Sulfur-driven autotrophic denitrification (SdAD) represents an effective alternative to
heterotrophic denitrification process for the treatment of organic carbon deficient or organic …

Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Nitrate is the most common water environmental pollutant in the world. Inorganic electron
donor-mediated denitrification is a typical process with significant advantages in treating low …

Autotrophic denitrification coupled with sulfide oxidation represents an interesting alternative
for the simultaneous removal of nitrate/nitrite and sulfide from wastewaters. The applicability …
