Predicting struvite formation in digestion
TL;DR: In this paper, an improved method was developed for predicting struvite precipitation potential in anaerobic digestion and post-digestion processes, considering the ionic strength effects on ion activities, magnesium phosphate complexation effect on ion speciation, and an experimentally derived struveite solubility constant.
