The application of thermal hydrolysis (TH) as pre-treatment to anaerobic digestion (AD) or as inter-treatment (between two AD stages) was considered and compared with the conventional digestion scheme. TH scenarios reduced the mass flow rate of biosolids (40–60%) as well as the ratio of solids (50–100%), organic matter (5–26%) and nitrogen (8–13%) destined to biosolids. Micropollutants showed a strong tendency to accumulate in the solid phase (more than 90% were sorbed) in spite of thermal and dewatering processes, but TH scenarios exhibited greater removal efficiency (80%) in comparison to conventional AD (50%), reducing the ratio of micropollutants destined to biosolids from a conventional 48% to 7–8%. These findings reveal that TH could increase the value of biosolids from sewage sludge treatment because of greater removal of pollutants and dewaterability.Este trabajo ha recibido financiación del Gobierno de España (MINECO-CTM2015-70722-R) y de la junta de Castilla y León y la Unión Europea a través de EU-FEDER (CLU 2017–09 and UIC 071)Elsevier2020info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://doi.org/10.1016/j.biortech.2020.123028http://uvadoc.uva.es/handle/10324/40677reponame:UVaDOC.
