Hello Everyone,
I have a question: what is the difference between the struvite in wastewater and struvite precipitation recovery for different organic wastes such as animal manure and swine manure? The struvite precipitation reactor recovers the digestate of organic waste as a liquid separation from organic waste.
Are the parameters affecting both processes the same? what are the factors that affect each process?
Thank you very much
Struvite shows promise as organic fertilizer
Thiessen Martens, a PhD candidate at the University of Manitoba’s department of soil science, trialled struvite on three crops between 2017 and 2019 at Libau in eastern Manitoba. She shared her findings during the Prairie Organics Conference on February 8.
Struvite is a phosphorus-rich crystalline material that can naturally occur in nutrient-rich waste water treatment systems if conditions are right — potentially clogging the system.

Dear Adam,
Very good question. In theory, if the processes are realized in certain conditions: liquid media, anaerobiosis, high nitrogen and Phosphorus concentration and rather warm environment, the processes (Water treatment and manure or other organic waste treatment) should result in struvite precipitation.
This would discard, for example, composting, as temperature is lower and there is no liquid phase.
If I get more specific info, I will let you know.
Cheers
