Vacuum Evaporation Of Wastewater As A Mean For Nutrient Recovery And Waste Heat Utilization In Biogas Plants

Original language description

Following significant financial incentives in European countries, biogas plants became a widespread technology for biomass conversion and electricity production. In 2015 more than 17 thousand plants were running in EU with total installed capacity over 8.3 GW,el. Despite undisputed advantages of this technology, there are still several issues that should be solved. One of them is an inefficient use of heat that is produced during the cogeneration process. Typically, only 20-40 % of the heat produced is utilized. A shortage of suitable technologies and low-potential character of the waste heat (around 90 °C) are the main reasons of this situation. Another issue is connected with wastewater (so-called digestate or fermentation residue) treatment and utilization. Digestate is a by-product of anaerobic fermentation of biomass and is especially rich in nutrients such as nitrogen, potassium or phosphorus. Is therefore mainly used as a natural fertilizer. However, nutrients concentration is quite low and wa
