 Anaerobic co-digestion of sewage sludge and slaughterhouse waste in existing wastewater digestersAhmad Reza Salehiyoun, Francesco Di Maria, Mohammad Sharifi, Omid Norouzi, Hamid Zilouei and Mortaza Aghbashlo Renewable Energy, 2020, vol. 145, issue C, 2503-2509 Abstract: The effect of co-digesting slaughterhouse waste (SHW) with waste mixed sludge (WMS) for possible implementation in a full-scale digester in an existing wastewater treatment plant (WWTP) was investigated. Biomethane potential (BMP) runs were activated using SHW:WMS ratios from 0% to 60% at total solids (TS) of 4% and 7%. Higher values of BMP of about 735 NLCH4/kg volatile solids (VS) were obtained for the run with a SHW:WMS ratio of 40% and TS = 4%. Continuous runs were also performed using the same SHW:WMS ratio at different organic loading rates (OLR). The maximum biomethane generation of 550 NLCH4/kgVS was achieved for an OLR = 1.5 kgVS/m3.day. Stability monitored by FOS/TAC showed values < 0.7 for OLR up to 2.0 kgVS/m3.day. The amount of SHW processable in the full-scale digester of the WWTP ranged from about 1.8 MgTS/day to 3.0 MgTS/day with a biomethane production of about 2300 Nm3/day and 1400 Nm3/day, respectively.
