Abstract

La présente invention concerne un procédé pour traiter des déchets liquides contenant de l'eau, notamment des eaux usées, les eaux usées étant chauffées et évaporées. Selon l'invention, de l'air humide est extrait et des substances solides contenues dans les eaux usées évaporées sont réduites, et l'air humide alimente un condensateur dans lequel l'eau se condense. Le procédé de l'invention se caractérise en ce que l'air quittant le condensateur est introduit directement dans les eaux usées à évaporer, et en ce que l'air circulant dans le circuit fermé est constamment saturé d'humidité. L'invention a également pour objet un dispositif pour mettre en oeuvre un procédé de ce type.
