The mass of dye taken up by the yarn or fabric divided by the total initial mass of dye in the water bath. Once the dyeing process reaches equilibrium, a portion of the dye remains in the dye bath and becomes part of the dye process wastewater. The exhaustion ratio depends on the quality of the dye and the characteristics of the fiber.These process waste water can be reused with the MMO Coated Electrodes.  These MMO coated electrodes very much used to remove the colour and odour. Also the MMO coated anodes with Titanium substrate shall be re coated, after the reasonable time. The attached images will be self explanatory.
