With the advancement of water ecological protection and water control standard, it is the
general trend to upgrade the wastewater treatment plants (WWTPs). The simultaneous …

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

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 …

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 …

Groundwater, as the most important drinking water source in arid regions of China, has been
polluted seriously by accumulated nitrate and heavy metals. An economic alternative with …

This study investigates the performance of a pyrite-based constructed wetland-microbial fuel
cell (PCW-MFC) in chemical oxygen demand (COD), nitrate (NO 3−-N), total inorganic …

Microbially-mediated redox processes involving arsenic (As) and its host minerals
significantly contribute to the mobilization of As in estuarine sediments. Despite its …

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 …

The inefficiency of nitrogen removal in pyrite autotrophic denitrification (PAD) and the low
