In the present work, degradation of azo dye polluted water is challenging for researchers and environmentalists. Azo dye polluted water is hazardous for living world. Many Techniques of photocataytic Degradation Physicochemical techniques include membrane filtration, coagulation/flocculation, precipitation, flotation, adsorption, ion exchange, ion pair extraction, ultrasonic mineralization, electrolysis, advanced oxidation (chlorination, bleaching, ozonation, Fenton oxidation and photo catalytic oxidation) are available in world. The most important dye removal techniques are Photo catalytic oxidation processes. Degradation of these azo dye by recently developed photo catalyst Methylene Blue immobilized Resin Dowex-11 is cheaper and very good alternative to replace costly traditional treatment and less efficient technologies for industrial application. This catalyst has potential to degrade all dye molecules and we recover 100% clean and transparent water from dark color textile effluent wastewater within few hour treatments by Methylene Blue immobilized Resin Dowex-11, photo catalyst. We use Tropaeolin O (Acid Orange 6), Methyl Orange, and Orange Gas model dye for experimental purpose; this is Azo dye and used in textile industries.
