Elimination of reactive dye hydrolyzates through chemical reactions

Residual colours and the COD-value can successfully be reduced in the textile industry with this processing technique. With the re-utilization of the decolourised permeate in the dying process, the amounts of chemicals, alkalis and salt additives can be reduced, and so can save costs for chemicals, water and waste water.
