Potential for potassium recovery as K-struvite
, 2016 Crystallization of NH₄-struvite (MgNH₄PO4:6H₂O) pellets has proven to be a successful method of recovering nitrogen and phosphorus from wastewaters. Thus far, little work has been done on potassium recovery since it is not considered a water pollutant, nor do we face potassium shortages. However, potassium is an essential plant macronutrient and we are

Biochar as a carrier of struvite precipitation for nitrogen and phosphorus recovery from urine
, 2018 Struvite precipitation is a promising approach to recover nitrogen (N) and phosphorus (P). However, poor solid-liquid separation of struvite precipitation crystallization can significantly decrease resource recovery efficiency.

Strategies to Enhance the Recovery of Phosphorus as Struvite During the Storage of Urine
Results in EngineeringPhosphorus is a non-renewable resource, and it will in future become increasingly scarce. Urine can be used as a valuable resource of phosphate. One way to create favourable conditions for recovering phosphorus as struvite from urine is to store urine and promote urea hydrolysis, before the recovery of phosphate.
