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

Biogas upgrade via ex-situ technologies

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic: 
Environmental biotechnology and bioenergy
The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more

Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale

Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic: 
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...Read more
