Title (EN) PROCESS AND PLANT FOR PURIFICATION OF AGRICULTURAL WASTE MATERIAL
(FR) PROCEDE ET INSTALLATION D'EPURATION DES LIQUIDES USES D'ORIGINE AGRICOLE
Abstract: front page image
(EN)A process and a plant for purifying agricultural waste liquid such as waste liquid from the processing of fruit, wherein the waste material initially is separated into a solid and water-soluble phase and where the aqueous phase further is provided with chitosan to flocculate the colloidally floating particles in the aqueous phase. The thus treated aqueous phase is passed through a pipe flocculator (2) and is subsequently treated by further adding of chitosan (4, 5, 12) and filtering through membrane filters (5) and coal filters (7) or vice versa. The process and plant is suited for purifying the waste water from olive oil pressing called alpechin.
(FR)Procécé et installation d'épuration des liquides usés d'origine agricole tels que les liquides restants après le traitement des fruits. Dans un premier temps, on sépare les liquides usés en un solide et une phase hydrosoluble, et l'on ajoute à la phase aqueuse du chitosan pour provoquer la floculation des particules flottant de manière colloïdale dans la phase aqueuse. On fait passer la phase aqueuse ainsi traitée dans un floculant tubulaire (2), l'on ajoute du chitosan supplémentaire (4, 5, 12), et l'on filtre ladite phase aqueuse à l'aide de filtres à diaphragme (5) et de filtres à charbon (7) et inversement. Le procédé et l'installation sont adaptés à l'épuration de l'alpéchine, c'est-à-dire le liquide résiduraire du pressage de l'huile d'olive.
