Excess brewery yeast co-digestion in a full-scale EGSB reactor
نویسنده
چکیده
In the full-scale the anaerobic co-digestion of brewery yeast using granular biomass was studied. Full-scale operation with 0.7 % yeast concentration showed a 38.5 % increase in the biogas production and a 26.2 % increase in the organic loading rate, which resulted in an increase of the biomethane/natural-gas substitute ratio from 10 % to 16 %.

Anaerobic co-digestion of excess brewery yeast in a granular biomass reactor to enhance the production of biomethane.
The anaerobic co-digestion of brewery yeast using granular biomass was studied on the lab, pilot and full-scale. The study shows no adverse effects in the co-digestion of yeast and wastewater in concentrations up to 1.1 (v/v)%. In concentrations up to 2.3% the process is manageable; however, not advisable. In concentrations over 2.8% the process exhibits failure due to the overload with suspend...
متن کاملBiogas Production from Brewer's Yeast Using an Anaerobic Sequencing Batch Reactor.
Renewable energy sources are becoming increasingly important in the beverage and food industries. In the brewing industry, a significant percentage of the used raw materials finishes the process as secondary resource or waste. The research on the anaerobic digestion of brewer's yeast has been scarce until recent years. One of the reasons for this is its use as a secondary resource in the food i...
متن کاملPost-treatment of UASB effluent in an EGSB reactor type using flocculent sludge
The performance of an EGSB (expanded granular sludge bed) reactor type using flocculent sludge was evaluated for the post-treatment of effluent from UASB reactor treating domestic sewage. A pilot-scale 157.5-L EGSB reactor was monitored during a 331-day period. The original concept of the EGSB reactor was based on the granular sludge use and by applying high upflow liquid velocities (vup). Howe...

Anaerobic digestion can be utilized to convert industrial wastewater into clean water and energy. The goal of this project was to set up lab-scale anaerobic digesters to collect data that will be used to develop and validate a predictive monitoring and controls solution to improve digester performance. The research project involved the design, construction, and instrumentation of lab-scale anae...
متن کاملUtilization of Co-digestion of Local Brewery Wastes and Cattle Dung as a Potential Source of Biogas and Organic Fertilizer
Biogas production from co-digestion of local brewery waste (BW) and cow dung (CD) was study for value added to this solid waste. The objective of this research was to fine the optimum condition for maximum biogas production and also examined the effectiveness of the biogas residue (liquor from anaerobic digestion process) as a nitrogen source for the production of okro. The experiments were per...
