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 ...

A Soft Sensor for Simultaneous Prediction of Struvite Purity and Recovery Rate. [PDF]

ACS Omega
Phosphorus is essential for all living organisms and is widely used in various industries. However, phosphorus resources are nonrenewable and may soon be depleted. Struvite, a high-quality slow-release compound fertilizer containing nitrogen, phosphorus, and magnesium, is a form of phosphorus recovery product.

Struvite recovery from domestic wastewater

, 2020
Worldwide, large amounts of phosphorus (P) rock are consumed annually in intensive agriculture and industry. P can be recovered from the ashes of mono-incinerated sludge, from concentrated wastewater streams such as sludge water of dewatered digested ...

Phosphate Recovery from Swine Wastewater by a Struvite Precipitation Electrolyzer [PDF]

Scientific Reports, 2019
Abstract Struvite precipitation electrolyzers are interesting environmental electrochemical reactors with potential applications for efficient phosphate recovery from wastewater, such as swine wastewater. In this paper, effects of phosphate concentration and pH on the struvite precipitation reaction rate were investigated.

Scaling Up of a Lightweight Aggregates System Based on Recovery Raw Materials and With Fertilisation Capacity: From Laboratory Prototype to Semi‐Industrial Production

Applied Research, Volume 5, Issue 4, August 2026.
Improved glass meltability enabled semi‐industrial prototyping of a residue‐derived PK fertiliser. Firing produced mechanically stable micropellets and induced partial vitrification, pore‐network reorganisation, delayed P release, but restricted K availability; 6‐month field trials on turfgrass and Photinia supported agronomic feasibility.

Recovery of Phosphorus in Animal Wastewater by Struvite Forming [PDF]

Journal of Biosystems Engineering, 2006
This study was carried out to recover phosphorus in animal wastewater using a magnesium source. , as a magnesium source, was shown a SP (soluble phosphorus) recovery rate of 98% in both the aeration and the NaOH tests to adjust pH around 8.5. In case of MgO, the recovery rate of SP were 88% with the aeration and 58% with the NaOH.

The Crystallization of Struvite and its Analog (K-Struvite) from Waste Streams for Nutrient Recycling

, 2016
The precipitation of struvite (MgNH4PO4·6H2O) and its analogue, K-struvite (MgKPO4·6H2O), from waste streams is widely recognized as a promising strategy for nutrient recovery owing to their elemental compositions and fertilizing properties. This chapter

Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, Volume 67, Issue 8, Page 680-685, August 2026.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.

Seawater as Magnesium Source for Struvite Recovery from Wastewater

, 2022
Phosphorus is essential for living organisms and is widely used in various industries. Phosphorus naturally exists as phosphates (PO43-) and is mainly exploited from phosphate ores, a mineral that is predicted to be exhausted in the next century.
