Abstract

Epuration de fluide en lit particulaire. Le fluide traverse un lit stationnaire parmi plusieurs compartiments ; le transport de lots de matière de lit s'effectue pendant des phases de transfert aux transitions entre phases de traitement successives ; pendant chaque phase de transfert, la matière de lit épuisée est vidée de l'un des compartiments et la matière de lit régénérée est amenée de la station de régénération dans l'un des compartiments de traitement de fluide pour y renouveler un lit, les compartiments étant vidés l'un après l'autre, pendant les phases successives de transfert dans l'ordre selon lesquels ils ont été alimentés en matière de lit régénérée. Epuration d'eaux résiduaires de blanchiment de pâte de bois.
