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

Struvite-(K), KMgPO46H2O, the potassium equivalent of struvite a new mineral
European Journal of Mineralogy, 2008 The new mineral struvite-(K) is the natural potassium equivalent to struvite NH4MgPO4·6H2O. It was discovered independently at two different localities: (1) at the famous sulphosalt locality Lengenbach in Binntal, Switzerland, where it occurs in a dolomitic rock of Triassic age, in close association with various Pb-As-sulphosalts (mainly rathite).

Lightweight magnesium phosphate cement composites with struvite recovered from wastewater [PDF]
, 2020 A feasibility study was performed to utilize struvite, in combination with magnesium oxide (MgO), to develop magnesium phosphate cement. The struvite was a wastewater by-product from a sewage treatment plant in British Columbia, Canada.
