Title (EN) AUTOMATED, QUANTITATIVE FILTRATION OF LIQUIDS
(FR) FILTRATION QUANTITATIVE AUTOMATISEE DE LIQUIDES
Abstract:
(EN) A system for automated filtration (24) of liquids for quantitative collection of desired filtrates or permeates (33) has a processor-controlled pump unit (25), which controls the rate of flow. The processor-controlled pump operates on data from pressure sensors (35, 36, 40) and a scale (37, 38) to control flow velocity and/or filter back pressure within the pressure.
(FR) L'invention concerne un système de filtration automatisée (24) de liquides permettant la collecte quantitative des filtrats ou perméats (33) souhaités. Ce système comporte un ensemble pompe (25) piloté par calculateur, lequel régule le débit. Pour réguler la vitesse d'écoulement et/ou la contre-pression du filtre au sein du système, l'ensemble pompe piloté par calculateur fonctionne sur la base de données provenant de capteurs de pression (35, 36, 40) et d'une balance (37, 38).
