High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification

Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.

Topic:

Environmental biotechnology and bioenergy

Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more

The effect of HRT in the successful bioaugmentation of CSTRs working under ammonia toxicity

Tzenos C., Christou M., Kalamaras S., (Corresponding) Kotsopoulos T.

Topic:

Environmental biotechnology and bioenergy

High levels of ammonia is a common inhibitory factor in anaerobic digestion (AD) resulting in low methane production and unbalance of the process. In the present study, the adjustment of the hydraulic retention time (HRT) and the bioaugmentation process (BP) are investigated to counter the negative...Read more
