Abstract
Un système de bioréacteurs traite un concentré deaux contaminées à laide dune combinaison de bioréacteurs à courant ascendant et descendant positionnés en aval dun mécanisme dosmose inverse ou dun autre concentrateur. Le système peut comprendre une configuration de sécurité intégrée, selon laquelle une eau de rinçage peut être ajoutée aux réacteurs en cas de panne de courant ou au moment déteindre les réacteurs. De nombreux systèmes dosmose inverse utilisent des traitements anti-écaillement en amont, de sorte que les filtres dosmose inverse ne sécaillent pas. Cependant, de tels traitements produisent des conditions de superconcentration de produits anti-écaillement dans leau contaminée traitée par les bioréacteurs. Un système de rinçage peut déconcentrer les bioréacteurs pour empêcher les produits anti-écaillement de précipiter et dencrasser les bioréacteurs.
