Verfahren und Vorrichtung zur Reinigung von Prozesswasser in einem hydrothermalen Karbonisierungsprozess

Die hydrothermale Karbonisierung erlaubt die Herstellung von Kohle aus Biomasse. Diese Biomasse kann aber zu Beginn des Karbonisierungsprozesse Bestandteile enthalten, die sich für die Karbonisierung nicht eignen. Neben groben Verschmutzungen durch Glasscherben etc. handelt es sich hierbei insbesondere um Sand und Schluff, wobei der Schluff sich durch einfache Filtermethoden aufgrund seiner Feinheit nicht entfernen lässt.
