Towards a Circular Phosphorus Economy: Electroless Struvite Precipitation from Cheese Whey Wastewater Using Magnesium Anodes

Applied Sciences
Phosphorus recovery from wastewater as struvite via electrochemical magnesium dosing is a promising approach to address the growing demand for fertilizers. However, its large-scale implementation is often constrained by energy requirements.

Removal of contaminants from liquid after the hydrothermal carbonization of sewage sludge using a combination of membrane techniques and struvite precipitation

Water Resources and Industry
Post-processing liquid (HTCL), generated from the hydrothermal carbonization (HTC) of sewage sludge, is a highly organic by-product and one of the primary challenges of this technology.

Synthesis and Characterisation of Struvite Family Crystals by An Aqueous Precipitation Method

MATEC Web of Conferences, 2016
Struvite (NH4MgPO4•6H2O) is a mineral often found as a scale deposit in an industrial process and piping. The common occurrence of struvite formation is a wide variety of environments.

Modelling struvite precipitation in anaerobic treatment systems

Water Science and Technology, 1994
Struvite precipitation is common in waste water systems containing high concentrations of dissolved orthophosphates, free and saline ammonia and magnesium ions, such as in anaerobic fermentation systems, often leading to severe fouling. It appears that a reduction of the partial pressure of CO2, ie.
