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
Use of a two-stage MBBR system for medium-strength dairy wastewater treatment
Katsara A., Iliopoulou A., Zkeri E., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
A two-stage Moving Bed Biofilm Reactor (MBBR) system consisting of a methanogenic and an aerobic reactor in series was used for medium strength dairy wastewater treatment. An energy analysis was conducted for the methanogenic MBBR to investigate its autonomy and its potential to act as a...Read more

Production and characterization of microalgal biomass from dairy wastewater
Iliopoulou A., Zkeri E., Panara A., Dasenaki M., Aloupi M., Fountoulakis M., Thomaidis N., (Corresponding) Stasinakis A.
Topic:
Environmental biotechnology and bioenergy
During the last decade, a large scientific effort has been directed towards the cultivation of microalgae in dairy wastewater. Among different microalgal species, Chlorella sorokiniana is a small, fast-growing, robust microalgae that can be grown under mixotrophic conditions. In the current study,...Read more
Evaluation of Pressure-Driven Membrane Processes for Nutrients Recovery from Dilute Effluents
Tsaridou C., Karanasiou A., (Corresponding) Plakas K., Karabelas A.
Topic:
Circular economy and industrial symbiosis
Results are presented from an ongoing R&D project, aiming at full utilization of dairy-industry effluents. Development of a membrane-based method is pursued, for treatment of digestate (after fermentation yielding bio-gas) to recover nutrients (N-NH4, P-PO4) and water for reuse/recycling or...Read more
