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 ...

Long‐Term Low‐DO Operation Changes the Ammonia Oxidizer Community and Oxygen Kinetics

Water Environment Research, Volume 98, Issue 10, October 2026.
Lower dissolved oxygen reduces energy demand for wastewater treatment but slows ammonia removal. This study investigates a pilot process maintaining complete nitrification, documenting ammonia oxidizer adaptation to low dissolved oxygen. ABSTRACT Low–dissolved oxygen (DO) biological nutrient removal is an attractive option for energy and cost reduction,
