The present invention relates to a process of concentrating an aqueous suspension of solid particles comprising the steps of adding at least one organic polymeric flocculant to the suspension thereby forming flocculated solids in which the flocculated solids are allowed form a layer of solids and thereby forming a more concentrated suspension in which the process comprises the addition of an effective amount of an agent that is selected from the group consisting of free radical agents, oxidising agents, enzymes and radiation, in which the agent is applied to the suspension prior to or substantially simultaneously with adding the organic polymeric flocculant and/or the organic polymeric flocculant is added to the suspension in a vessel and the agent is applied to the suspension in the same vessel. The process is particularly suitable for solids liquid separation in which the flocculated solids are allowed to settle by sedimentation in a gravity thickener.
La présente invention concerne un procédé de concentration d~une suspension aqueuse de particules solides comprenant les étapes suivantes : ajouter au moins un floculant polymérique organique à la suspension afin de former des solides floculés, lesdits solides floculés formant une couche de solides, formant ainsi une suspension plus concentrée, ledit procédé comprenant l~addition d~une quantité efficace d~un agent choisi parmi les radicaux libres, les oxydants, les enzymes et les radiations, ledit agent étant appliqué à la suspension avant ou d~une manière sensiblement simultanée à l~ajout du floculant polymérique organique et/ou le floculant polymérique organique étant ajouté à la suspension dans une cuve et l~agent étant appliqué à la suspension dans la même cuve. Le procédé convient notamment à la séparation de solides et de liquides, au cours de laquelle on laisee les solides floculés précipiter par sédimentation dans un épaississeur par gravité.
