Title
(EN) HEAD SPACE FOR DEPTH FILTERS AND METHOD OF USING SAME
(FR) ESPACE DE TÊTE POUR FILTRES EN PROFONDEUR ET SON PROCÉDÉ D'UTILISATION
Abstract
(EN)
Depth filters with optimized head space are provided, as well as methods of optimizing the head space in depth filters, and methods of filtration with depth filters having optimized head space, including clarification of flocculated feed streams where pretreatment may include any of lowering cell culture pH, addition of polymers (uncharged or charged), or addition of salts to precipitate out solubilized impurities resulting in high insoluble biomass.
(FR)
L'invention concerne des filtres en profondeur ayant un espace de tête optimisé, ainsi que des procédés d'optimisation de l'espace de tête dans des filtres en profondeur, et des procédés de filtration avec des filtres en profondeur ayant un espace de tête optimisé, y compris la clarification de courants d'alimentation floculés dans lesquels le prétraitement peut comprendre l'un quelconque parmi l'abaissement du pH de la culture cellulaire, l'addition de polymères (non chargés ou chargés), ou l'addition de sels pour précipiter les impuretés solubilisées conduisant à une biomasse insoluble élevée.
