Recovery of hot water, dyes and auxiliary chemicals from textile wastestreams☆

Abstract The recovery of hot water, dyes and auxiliary chemicals from a continuous dye range has been demonstrated using a full-scale dynamic membrane hyperfiltration system. The recovered hot water has been suitable for reuse greater than 99% of the time. The reuse of recovered dyes and chemicals depends on the compatability of the dyes and chemicals in the concentrate with the dyes and chemicals required for various production formulations.
