Rapid Denitrifying Granular Sludge Formation Methods for Closed-recirculating Seawater Aquaculture System

Journal of Water and Environment Technology
Denitrification is an important process for water quality control in recirculating aquacultural systems. Denitrifying granular sludge reactors, such as upflow sludge blanket (USB) reactors, can achieve a high NO3∁EN removal efficiency under a short ...

Methane Production Reduced by Lignin Derivatives in Pulping Wastewater: Inhibition of Free Hydrolase

Fermentation
The lignin derivatives generated during pulping might be responsible for the suboptimal performance of anaerobic reactors during the treatment of pulping wastewater. However, the exact mechanisms by which these derivatives exert influence remain unclear.

Long‐term assessment of the effect of OLR, HRT and temperature on domestic sewage treatment using AnMBR to enhance biomethane production

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 6, Page 2368-2378, November/December 2026.
Abstract The objective of this study was to evaluate the potential of an anaerobic membrane bioreactor (AnMBR) to treat domestic sewage by removing organic matter and nutrients while producing biogas. AnMBRs combine anaerobic digestion with membrane filtration, and stand out for their low energy consumption, low sludge production and potential for ...

Reusing water, reshaping nitrogen: Unravelling nitrogen dynamics in soils receiving treated wastewater

Journal of Environmental Quality, Volume 55, Issue 6, November/December 2026.
Abstract Soils are increasingly receiving treated wastewater (TWW) to support crop production and protect natural resources. However, besides water, various inputs, such as soil nutrients (salts), organic carbon, and various contaminants of emerging concern, including antibiotics, antibiotic resistance genes, pharmaceutical compounds, heavy metals, and

Phosphorus phytoavailability of residuals from wastewater processed for phosphorus reduction

Soil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.
Abstract Wastewater from sewage or animal processing plants may require phosphorus (P) removal before being discharged to agricultural fields. The objectives of this study were to (1) characterize the chemical composition of wastewater from a pork processing plant treated for P reduction by adding aluminum sulfate (AlP) or ferric chloride (FeP); (2 ...
