Abstract :

Synthetic dyes are fequently used in textile industry and are important environmental problem due to the color, high chemical oxygen demand, pH, temperature, environmental aesthetic and toxicity effects in textile wastewater. These kind of wastewaters are requires advanced clarification methods due to having high concentrated complex organic and surface active substances that separates hardly through their complex chemical structure. The dying agent consists of the chromophore group that gives molecule the color and functional group that bounds the dye to the fiber. Textile dyes should be removed from the environment directly as being highly toxic and destructive to the environment. Wastewater that contains that unremediated waters diminish the light permeability and inhibit the photosynthetic activity. It causes death of the species that can not tolerable to short oxygene as the dissolved oxygene amount is lessened. One of the other consequences of these discharges is the emerge of toxic-carcinogenic aromatic amines. This reason, textile industry wastewater should not discharge to the environment directly, should be remediated. In this study, the problems that was mentioned before was tried to be solved with the ultrasound system.The effects of Na2SO4, NaNO3, NaHCO3, N2 were investigated in the ultrasound environment. Different frequencies are applied individually and sequently. It was observed that with less chemical consumption and more qualified wastewater treatment can be handled by using the ultrasound. With the aid of ultrasound system; it is possible to have less chemically contamineted waters and better applications in textile dye decolorization. Key Words: Ultrasound, Color, Water treatment
