Abstract

The bio-gas industry is currently facing challenges in terms of post-treatment adjustments and further handling of the anaerobic digested residue or digestate. This is due to the low dry matter content of the effluent when transported through long distances for the final disposal as a bio-fertilizer in agricultural fields. Improvement of the performance of separation processes from liquid to solid is of interest. Commonly Jar-test are performed in order to adjust flocculant dosages prior to the dewatering of the digestate. Shear rheology and CFD provided in this study, an insight of the separation from a physical perspective.
