Abstract

L'invention concerne des systèmes de récolte et de culture d'algues et des procédés de production de concentrations élevées de produit d'algues avec une énergie minimale. Dans un mode de réalisation, un système et un procédé de filtration à impasse comprennent au moins un réservoir et une pluralité de membranes à fibres creuses positionnées dans le ou les réservoirs. Un milieu d'algues est tiré à travers les membranes à fibres creuses de telle sorte qu'un rétentat et un perméat sont produits.
