Optimization of Struvite Precipitation for Landfill Leachate Treatment

, 2017
Sanitary landfill is the most preferred municipal solid waste disposal method. The production of highly polluted leachate is a major disadvantage of sanitary landfills. In this study, optimization of struvite precipitation to remove ammonium from landfill leachate was conducted by using Response Surface Methodology (RSM) and Central Composite Design ...

Recovery of nitrogen from saponification wastewater by struvite precipitation

Water Science and Technology, 2010
In general, saponification wastewater produced from the separation process of rare-earth elements contains high ammonium concentration. In this study, a series of experiments were conducted to investigate the parameters to enhance the struvite precipitation potential for ammonium removal from the wastewater having an ammonium concentration of 4,100 mg ...

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 ...

Evaluation of Novel Isatin–Schiff Base Derivatives: Monoamine Oxidase Inhibition and Antimicrobial Assessment

ChemMedChem, Volume 21, Issue 16, 27 August 2026.
Five novel series of isatin–Schiff base derivatives are synthesized and evaluated for neuroprotective and anti‐infective potential. The compounds demonstrate exceptional, reversible, and competitive monoamine oxidase inhibition, with chloro‐substitutions dictating isoform selectivity.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, Volume 6, Issue 8, August 2026.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

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 ...

Nutrient Removal and Recovery: Hazenite Precipitation From Livestock Manure Wastewater

Water Environment Research, Volume 98, Issue 8, August 2026.
This study presents an optimized precipitation process for complex livestock wastewater, achieving > 90% concurrent removal of phosphorus, magnesium, and ammoniacal nitrogen. The system successfully drives targeted Hazenite (KNaMg2(PO4)2.14H2O) crystallization, recovering essential nutrients into a high‐value, slow‐release agricultural fertilizer ...

Conservative Management Enabling Spontaneous Passage of an Idiopathic Primary Spontaneous Enterolith: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Enterolithiasis—formation of stone concretions within the gastrointestinal tract—is an uncommon and underrecognized cause of intermittent abdominal symptoms and acute bowel obstruction. Primary (true) enteroliths originate within the bowel lumen and are usually associated with focal stasis from anatomic or inflammatory pathology; idiopathic ...

Struvite Production From Wastewater: Effect of Magnesium‐to‐Ammonia Ratio and Stirring Velocity on Precipitation Efficiency and Settling Behavior

CLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
This study demonstrates that stoichiometric Mg2+:PO43− excess (1.1:1) and slow 10‐min dosing are critical for maintaining low supersaturation, yielding large crystals (>0.84 mm) and rapid settling (5.5–10.1 cm/min). This strategy optimizes nutrient recovery (≥80%) and solid–liquid separation without flocculants, proving viable for complex industrial ...
