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: In this paper, the feasibility of applying reverse osmosis (RO) membrane separation to reduce fluoride load to less than 1 kg/d was investigated, and the design parameters of a small RO separation unit were estimated.

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 paper, a detailed comparison and evaluation of different kinds of organic absorbent was undertaken in purpose of toluene absorption, and experiments were performed to check gas-liquid partitioning and viscosity.
