The phase separation by decanter allows to purify the suspended particles of dry matter. After division, the solid fraction represents 10 to 20% of initial weight, which allows to have a capture rate of phosphorous up to 80% and 30 % nitrogen.
How does it work ? The matter is injected in the central part of of the decanter, the liquid is immediately projected on the separator’s walls thanks to centrifugal force.
Then, an auger pushes the solid particles towards the conical section, where they are squeezed and extracted.
– liquid inside = Better drying.
+liquid outside = Better nutrient extraction.
