Phosphorus Recovery from Municipal Wastewater: Brucite from MgO Hydrothermal Treatment as Magnesium Source

open access: yesCrystals, 2023
Crystallization of struvite (MgNH4PO4·6H2O, MAPH) for both N and P recovery from municipal wastewater is an attractive alternative. The low magnesium concentration in municipal wastewater calls for low-cost magnesium sources.

Kinetics of Struvite Precipitation: Effect of the Magnesium Dose on Induction Times and Precipitation Rates [PDF]

open access: yesEnvironmental Technology, 2007
The presence of white deposits in specific areas of wastewater treatment plants is generally the consequence of the spontaneous formation of a mineral called struvite. Struvite forms when the levels of phosphate, ammonium and magnesium naturally available in wastewater effluents reach a minimum molar ratio 1:1:1 under specific conditions of pH ...

Microbial Phosphorus Removal and Recovery by Struvite Biomineralisation in Comparison to Chemical Struvite Precipitation in Municipal Wastewater

open access: yesSSRN Electronic Journal, 2022
Microbial biomineralisation is attracting significant interest as an innovative process to recover nutrients from wastes. Nevertheless, little is understood about the requirements to form struvite using biological pathways in wastewater and how does this compare with conventional chemical processes.

The role of pH on the biological struvite production in digested sludge dewatering liquors

open access: yesScientific Reports, 2018
Struvite production mediated by bacteria has opened up a new route for phosphorus recovery from wastewater streams but its application to digested sludge dewatering liquors is not yet well understood.

Kinetics and morphological characteristics of struvite (MgNH4PO4.6H2O) under the influence of maleic acid

open access: yesHeliyon, 2020
This work reports a stirred-batch lab crystallization to examine the influence of maleic acid (HO2CCHCHCO2H), and temperatures (30 and 40 °C) on crystallization kinetics and morphology of struvite.

Morphogenesis and evolution mechanisms of bacterially-induced struvite

open access: yesScientific Reports, 2021
Bacteria are able to induce struvite precipitation, and modify struvite morphology, leading to the mineral with various growth habits. However, the relevant work involving the morphogenesis is limited, thereby obstructing our understanding of bacterially

Phosphorus retention and agronomic efficiency of refined manure-based digestate—A review

open access: yesFrontiers in Sustainable Food Systems, 2022
Digestate, a by-product from anaerobic digestion of organic materials such as animal manure, is considered a suitable plant fertilizer. However, due to its bulkiness and low economic value, it is costly to transport over long distances and store for long

Optimizing Struvite Crystallization at High Stirring Rates

open access: yesCrystals, 2023
Phosphorus and ammonium can both be recovered in the presence of magnesium through struvite (MgNH4PO4·6H2O) crystallization. The present work aimed to optimize struvite crystallization at turbulent solution flow.
