In your case, I advise you after primary treatment to apply biological treatment with active silt or other (secondary treatment). After that, solve the problem of the most simple and effective color removal using a color reducer or other (tertiary treatment).

I'm with Mr.Gediminas. In our textile ETPs when no pre-anaerobic stages are, conventional CMAS could easily provide a yellow pale effluent. Downstream we dose decolouring agent (often quaternary cationic polymer) to comply with quality at discharge. That's.
We had excellent results on sulphur black with coupled anaerobic-aerobic bio processes, where low ORP and reductive environment (ANA) strongly promoted/helped a fully-biological decolouring.
