Biodegradability and activity tests of winery wastewater at 37 °C using inoculum from a paper mill suggested hydrolysis as the rate limiting step with hydrogen the predominant pathway to methane. Scaling-up to a Hybrid-EGSB showed that after 100 days acclimation at moderate temperatures (20 ± 2 °C) a 70 ± 2% COD removal is achievable, applying an OLR of up to 15.32 kgCOD·m−3·day−1 and an SLR of 3.83 kgCOD·kgVSS−1·day−1 respectively. Conventional operation and mesophilic temperature increase improved COD removal efficiency (≤96%) while sCOD concentration met the European COD effluent standards. COD:CH4 conversion reached 0.31 ± 0.07 m3 CH4·kgCODremoved−1; COD:biogas estimated 0.45 ± 0.06 m3gas·kgCODremoved−1, ∼300% higher than the acclimation period. Operation remained stable at OLR < 39 kgCOD·m−3·day−1, which corresponds to an SLR of 4.8 kgCOD·kgVSS−1·day−1. This limit results in an Alkbicarb.:Alktot ∼0.31 and a pH ∼6.51, an irreversible status that demonstrates the limits of anaerobic treatment of winery wastewater with this reactor setup.
