Strategy of adjusting recirculation ratio for biohythane production via recirculated temperature-phased anaerobic digestion of food waste

Food Waste Disposal Using Anaerobic Digestion

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Comparison of Temperature Phased and Other State of the Art Processes for Anaerobic Digestion of Municipal Solid Waste

The temperature-phased anaerobic digestion (TPAD) process was used for the anaerobic digestion of the source separated biodegradable organic fraction of municipal solid waste (OFMSW). The TPAD process was used to co-digest OFMSW with primary wastewater solids (PS) at ratios of 20:80, 40:60, 60:40, and 80:20 O FM SW :PS.

Two-phase thermophilic anaerobic digestion process for biohythane production treating biowaste: preliminary results.

This paper deals with the optimization of a two-phase anaerobic process treating biowaste for hydrogen and methane production. Neither physical nor chemical pre-treatments were used to optimize the process. The work was carried out at pilot scale, using two CSTRs (200 and 380 L working volume respectively) both maintained at thermophilic temperature (55 C) and fed semi-continuously with biowast...

Anaerobic digestion of autoclaved and untreated food waste.

Anaerobic digestion of autoclaved (160°C, 6.2 bar) and untreated source segregated food waste (FW) was compared over 473 days in semi-continuously fed mesophilic reactors with trace elements supplementation, at organic loading rates (OLRs) of 2, 3, 4 and 6 kg volatile solids(VS)/m(3)d. Methane yields at all OLR were 5-10% higher for untreated FW (maximum 0.483±0.013 m(3) CH4/kg VS at 3 kg VS/m(...
