Development of a novel vacuum evaporator for liquid digestate treatment
Original language description
Vacuum evaporation is a proven technology for a liquid digestate treatment with the advantage of simple construction, robust operation and waste heat utilization. Evaporators are capable of significant dewatering of the liquid digestate up to the 15 % of dry matter content (without a stirrer). However, high investment cost, chemicals consumption and utilization of subsidized and thus expensive electricity are the main obstacles for its expansion in the Czech Republic. To be acceptable for plant operators, beside price and reliability, a vacuum evaporator must meet all requirements for its product’s (concentrate, separated water) quality. Separated water should be purified enough so it could be directly discharged. The concentrate should contain most of original nutrients and must be usable as a fertilizer. To meet rising demand for feasible digestate treatment technology in the Czech Republic, a multi-stage flash (MSF) evaporator has been subjected to an extensive development, which is further descri
