Since the elements recovery to the solid fraction is one of the goals of solid-liquid separation, we calculated the separation index (SI) for dry matter, organic N, and total P. The SI is the ratio between the mass of an element recovered to the solid fraction and its initial mass in the processed volume of digestate.
