Hydrothermal multivariable approach: Full-scale feasibility study Electron. J. Biotechnol.
Pérez-Elvira,Sara I; Fernández-Polanco,Fernando; Fernández-Polanco,María; Rodríguez,Pilar; Rouge,Philippe.
A process configuration combining thermal hydrolysis (TH) and anaerobic digestion (AD) of sludge has been studied with the objective of analysing the feasibility of the technology for full scale installations. The study has been performed through pilot scale experiments and energy integration considerations, and a scheme of the most profitable option is presented: thermal hydrolysis unit fed with 7% total solids (TS) secondary sludge, anaerobic digestion of the hydrolysed sludge together with fresh primary sludge, and a cogeneration unit to produce green electricity and provide hot steam for the thermal hydrolysis process. From a technical and practical point of view, the process scheme proposed is considered to be feasible. Based on the results of the...
