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

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
