In this study we evaluated the importance of membrane technology in the purification of some existing dyes in wastewater from step textile finishing.

Abstract: (french)
Aujourd'hui, la plupart des colorants synthétiques utilisés dans le domaine de l'ennoblissement textile sont entre autres des colorants réactifs solubles dans l'eau et des colorants de cuve. L'utilisation de ces colorants produit une quantité importante d'effluents colorés visibles et indésirables pour la santé humaine et l'environnement. Dans ce travail nous avons évalué l'importance des techniques membranaire dans la purification des quelques colorants existant dans les eaux résiduaires issues de l'étape de l'ennoblissement textile. Tout d'abord, nous avons quantifié le pouvoir de rétention des solutions colorées (Indigo/Rouge de cibacrone), en employant une membrane asymétrique, que nous avons synthétisée au laboratoire et qui est à base de deux copolymères physique polysulfone (PSU) et polyétherimide (PEI).
Les taux de décoloration primaire obtenue par le procédé d'ultrafiltration sur ces solutions colorées modèles à base du rouge de cibacrone à PH=6.75 et l'indigo à PH=11.30, sont respectivement 71.20% et 85.36%.
