Abstract: New ecolabels for textile products and tighter restrictions on waste-
water discharges are forcing textile wet processors to reuse process water and
chemicals. This challenge has prompted intensive research in new advanced
treatment technologies, some of which currently making their way to full-scale
installations. prise polishing treatments such as Ðltration, chemical
oxidation and specialized ulation techniques and pre-treatment steps includ-
ing anaerobic digestion, Ðxed-Ðlm bioreactors, FentonÏs reagent oxidation, elec-
trolysis, or foam Ñotation. Though several of these new technologies are
promising in terms of cost and performance, they all su†er limitations which
require further research and/or need broader validation. A segment of the
research deals with the separate handling of speciÐc sub-streams such as dyebath
effluents to which membrane Ðltration is sometimes applied. The main limitation
of this approach is the treatment of the concentrate stream. The spectrum of
available technologies may, in the future, be further broadened to include
fungi/H2O2-driven oxidation, specialized bio-sorptive processes, solvent extrac-
tion, or photocatalysis.( 1998 SCI
