Co-digestion of cheese whey with sewage sludge for caproic acid production: Role of microbiome and polyhydroxyalkanoates potential production
نویسندگان
چکیده
The main aim of this work was to evaluate the efficiency producing caproic acid and other volatile fatty acids using a co-digestion between cheese whey sewage sludge in continuous reactor. effect two different feeding regimes (one per day) three hydraulic retention times (HRT) (15, 10 6 days) on organic production were studied. optimal conditions for process days HRT, 2 cycles day, reaching maximum degree acidification 44%. Under these conditions, most abundant acid. analysis microbial community dynamics reactor during HRT changes revealed microbiome enriched organisms involved production. Additionally, polyhydroxyalkanoates stream as verified fed-batch experiment obtaining copolymer formed by hydroxybutyrate, hydroxyvalerate hydroxyhexanoate.

Anaerobic Co-digestion of Sewage Sludge with Cheese Whey under Thermophilic and Mesophilic Conditions
Anaerobic digestion of sewage sludge (SS) and co-digestion with cheese whey (CW) was evaluated in batch conditions under mesophilic and thermophilic regimens. Results indicated that the co-digestion can be successfully attained despite some inhibitory stages that may be initially present due to the accumulation of volatile fatty acids. Degradation of the mixture SS-CW followed a similar pattern...

Biogas yield of mixtures of cattle slurry and cheese whey, rates of production of methane, removal efficiencies of chemical oxygen demand (COD) and biological oxygen demand (BOD) were investigated at 35 °C. Stable biogas production of 621 l/kg volatile solids at a hydraulic retention time of 42 days in a mixture containing 50% slurry and whey was obtained. The concentration of methane in the bi...

Abstact: The aim of the research project was to carry out the co-digestion of organic fraction of solid municipal waste in the form of source separated kitchen waste and sewage sludge. The influence of the kitchen waste as a co-substrate on the stability and efficiency of the process was determined. Mesophilic fermentation (36 ̊C) was conducted for sewage sludge as well as mixtures of sewage slu...
