Treating wastewater from anaerobic fermentation by means of vacuum evaporation
Original language description
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.
