Název v původním jazyce
Treating wastewater from anaerobic fermentation by means of vacuum evaporation
Popis výsledku v původním jazyce
Treatment of liquid effluents from anaerobic digestion is one of the central issues of current biogas plants operation. High costs for storage and transportation could be decreased using a suitable technology for nutrient recovery or volume reduction. Vacuum evaporation is an option with the advantage of robust operation and waste heat utilization. This study investigates operational characteristics of multi-stage flash evaporator. As the results suggests, the evaporator can possible reach high volume reduction, but the separated water must be subjected to a further treatment since it contains around 3 000 ppm of ammonia. Ammonia stripping, acid scrubber or reverse osmosis can serve as follow-up technologies. A proper techno-economic assessment must be done to secure feasibility of a project.
