TL;DR: In this article, the state of the art of different processes currently used for the treatment of dye house wastewaters and evaluated a four-step process to recover the water and the mineral salts, while leaving the spent dyes in the reject stream.

TL;DR: A comparative review of the current legislations on the dyeing industry emissions is given, first in France and then in other countries around the world.

TL;DR: The coagulation-flocculation-decantation process used to optimize water recovery from the concentrate shows that it is possible to recycle a great volume of water using a small decanter area, since the concentrate flow rate is low.

TL;DR: In this article, a process for the treatment of used reactivedye baths which consists of four steps: pre-filtration, neutralization, nanofutration and reverse osmosis is presented.

TL;DR: In this article, a feasibility study performed on a variety of nanofiltration membranes with different characteristics shows that for this membrane range the separation is poorly influenced by the membrane cut-off but greatly influenced by membrane chemistry.
