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 ...

Struvite precipitation potential for nutrient recovery from anaerobically treated wastes [PDF]

, 2001
Geochemical equilibrium speciation modeling was used to determine optimum conditions for precipitation of magnesium ammonium phosphate, or struvite, for the recovery of nutrients from anaerobically digested wastes.

A practical electrodialysis model for accelerating system development

AIChE Journal, Volume 72, Issue 9, September 2026.
Abstract Empirical optimization of electrodialysis (ED) is dependent on repetitive experiments with incremental adjustments, which is cost prohibitive at scale. While models can reduce the costs associated with optimization and scale‐up, existing ED models are limited in application to specific use cases and tend to be developed for the exploration of ...

Recovery of nitrogen and phosphorus from anaerobically treated wastes using struvite precipitation [PDF]

, 1997
Struvite, or magnesium ammonium phosphate hexahydrate, is a mineral that commonly precipitates when ammonium, phosphate, and magnesium ions are released during the anaerobic digestion of wastewater.

Techno-economic analysis of struvite and ammonium sulphate recovery from source-separated urine at multi-university scale

Water Research X
Conventional nitrogen fertiliser production via Haber–Bosch process is highly resource-intensive, while phosphorus fertilisers rely on phosphate rocks, a finite resource vulnerable to depletion.

Evaluation of porous concrete leachate to improve water quality

Journal of Environmental Quality, Volume 55, Issue 5, September/October 2026.
Abstract Porous concrete is increasingly explored as a multifunctional material for water quality improvement, stormwater management, and emerging agricultural applications. However, uncertainties remain regarding nutrient and trace metal leaching, particularly for freshly cast concrete. This study investigated the time‐dependent leaching behavior of a

Biomineralization of Nickel Struvite Linked to Metal Resistance in Streptomyces mirabilis

Molecules, 2022
Biomineral formation is a common trait and prominent for soil Actinobacteria, including the genus Streptomyces. We investigated the formation of nickel-containing biominerals in the presence of a heavy-metal-resistant Streptomyces mirabilis P16B-1 ...

Using P‐Mobilization Traits in Modern Maize Varieties for Optimizing the P Fertiliser Use Efficiency of Struvite Under P Limitation: First Evidence From a Pot and Field Trial

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Introduction Current recycling measures for closing the phosphorus (P) cycle are limited by the lower fertiliser use efficiencies of recycled products. Increasing P use efficiency (PUE) through maize genotype selection and management may offer a sustainable solution, but the potential of variety choice and its interaction with placed ...
