摘要
Method and device for the treatment of effluents containing inks, especially water-based inks, by separation, with a view to obtaining, on the one hand, sludge containing the inks and, on the other hand, the clarified effluent. According to the invention a flocculation of the effluent is carried out by the action of a flocculating agent followed by continuous centrifuging of the effluent, consisting of an acceleration of between 1,000 and 20,000 g while avoiding an air-liquid interface during the centrifuging. Application of the invention to the treatment of effluents containing water-based inks, from paper mills, cardboard manufacturing plants and bag manufacturing plants. IMAGE
