important consideration for municipalities in Canada and throughout the world. Phosphorous discharge into_x000D_
streams, rivers, and lakes is one of the main drivers of eutrophication of these water bodies, where the presence_x000D_
of high levels of biological nutrients results in increased growth of plants and algae. This increase subsequently_x000D_
results in depletion of oxygen levels in water bodies which has devastating effects on fish and overall_x000D_
biodiversity within aquatic ecosystems. Removal of phosphorous from wastewater is thus a key area of_x000D_
research and development in Canada_x000D_
Ostara Nutrient Recovery Inc. (Ostara) has developed technologies which enable the recovery of phosphorous_x000D_
from wastewater streams in a way such that the recovered phosphorous containing solids (struvite) may be used_x000D_
as a slow-release fertilizer. Ostara's core technology is the Pearl® fluidized bed reactor, is able to recover up to_x000D_
50% of phosphorous from a wastewater treatment plant and outputs (from the process) phosphorous-rich_x000D_
fertilizer production, in a form ready for distribution. At the heart of this technology is a complex multiphase_x000D_
fluidized crystallization process where polydisperse (struvite) solid particles are dispersed in a_x000D_
multi-component liquid phase (wastewater)._x000D_
Further advancement of the Ostara's Pearl reactor technology requires multiphase CFD simulations to enable_x000D_
resolution of the internal multiphase hydrodynamics and, simultaneously, the mass transfer resulting from the_x000D_
crystallization process occurring at the solid/liquid interface. This research involves the use of the "spectrum"_x000D_
of two-phase flow models in order to determine the most accurate one for Ostara's unique polydisperse_x000D_
