EP 1050512 A UPAB: 20010110 NOVELTY - Before separation of the sludge, amphiphilic agents are added. DETAILED DESCRIPTION - Preferred features: The addition converts the sludge into a state in which it settles under gravity into a compact sediment with clear supernatant liquor. Settlement under gravity continues for 1 hour, or preferably only 15 minutes. Following sedimentation, the liquid is separated by centrifugation. The sediment is then pressed to remove more liquid, which is intercepted. The solid phase is briquetted. The liquid phase is filtered, adding the solids arising, to the previously-separated solid phase. Amphiphilic agent is separated from the liquid and the solid phases by distillation and drying, respectively. It is then r...
