Abstract

L'invention concerne également des procédés, des systèmes et des supports lisibles par ordinateur comprenant des instructions d'utilisation d'un système de filtration en céramique, le système de filtration en céramique comprenant un canal d'alimentation et une membrane en céramique. Les étapes comprennent l'introduction de liquide dans le système de filtration céramique par l'intermédiaire du canal d'alimentation de telle sorte que le liquide passe à travers la membrane en céramique dans une première direction pour devenir un perméat séparé du canal d'alimentation par la membrane en céramique, arrêtant l'alimentation du liquide dans la première direction, retirer le liquide du canal d'alimentation tout en introduisant du gaz dans le canal d'alimentation, et après l'élimination du liquide du canal d'alimentation, forcer le perméat dans une seconde direction opposée à la première direction à travers la membrane en céramique et dans le canal d'alimentation.
