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 …

Nitrogen removal through microorganisms is the most important pathway in constructed
wetlands (CWs). In this review, we summarize the microbial coupling mechanisms of …

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 …

Anaerobic digestion, an economic and energy-efficient biological process, is extensively
applied in the treatment of a variety of wastewater streams and organic wastes. However …

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 …

The aim of this work was to demonstrate the operation of a large pilot-scale submerged
anaerobic membrane bioreactor (5.0 m 3) for biogas production from municipal wastewater …

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 …

The potential of bio-energy recovery from real municipal wastewater was investigated using
a one-stage pilot-scale submerged anaerobic membrane bioreactor (AnMBR) for a range of …

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 …
