I agree with Mr.Boyter: "answer depends on the level of color, types of colorants...". But with Vacuum Evaporators, we already treat a lot of different kind of waste water with dyes and pigments. If you send us a sample, we can test it in our laboratory in Italy.
Electrical consumption vary from 100-130 Wh/liter to 10-20 Wh/liter in case you have hot fluid in your factory (for example steam, hot water, exhaust gas, etc....). Send us (p.cesana@schell-international.com) more details regarding your wastewater, in order to design a proper machine maybe similar to the one shown in this link: colourants contamined effluent treat to save water reused for production.
