Fig. 8: Pictorial depiction of dye degradation processes.

Figures representing dye degradation represented through a change in color of effluent during combination of treatment processes of Coagulation and Flocculation (C&F), Activated Sand Filter (SF), Photocatalytic ZnO NanoMat (NM), Poly(acrylonitrile) (PAN), and Activation Carbon filter (ACF) for (a) textile and steel effluent (right to left), (b) Textile effluent (left to right).
