If we want to manage a textile zero liquid discharge. We have Biological treatment (Aerobic), MBR, RO, Physiochemical, MEE systems to manage the same. Raw effluent color/COD: 2748 Hz/1900 ppm and MBR out: 850 Hz/150ppm. RO reject: 8500 Hz/15000ppm.

I think the use of advanced oxidation may be viable. The use of hydrogen peroxide and UV degrades the chromophores of most dyes including Azo dyes. The capital expenditure may not be high as Peroxide is cheap and UV is also not that expensive. However, the textile effluent load must be first tested to ascertain the strength of UV needed to degrade the dyes thus reducing the COD level sgnificantly
