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 …

Eutrophication is a global concern that has severely deteriorated aquatic ecosystems. This
phenomenon has impacted the freshwater bodies (such as lakes and rivers) across the …

Iron sulfides-based autotrophic denitrification (IAD) is a promising technology for nitrate and
phosphate removal from low C: N ratio wastewater due to its cost-effectiveness and low …

Deep nitrogen removal from low-carbon wastewater is a pressing water treatment challenge
as of yet. Eight sets of vertical-flow constructed wetland (VFCW) intensified by pyrite were …

Iron-assisted biological wastewater treatment processes have shown a promising potential
in removing various types of contaminants. Synergistic effects between iron and microbes on …

Partial nitritation-anammox (PN-A) process, which significantly reduces energy and
chemical input compared to the conventional biological nitrogen removal process, is a game …

In this study, denitrification was performed using pyrite as sole electron donor. The nitrate
reducing rate ranged from 0.61 to 0.95 mM/d. The production of nitrous oxide (N 2 O) was …

The use of constructed wetlands for wastewater treatment is rapidly increasing worldwide
due to their advantages of low operating and maintenance costs. Denitrification in …

To date, there is a lack of systematic investigation on the elemental sulfur-driven autotrophic
denitrification (SDAD) process for removing nitrate (NO 3−-N) from mariculture wastewater …

Sulfur-driven autotrophic denitrification (SDAD), a process suited for the treatment of
nitrogen and sulfur-polluted wastewater without extra supplement of organic carbon, is a …
