REMOVAL OF DYE FROM WASTEWATER USING AGRICULTURAL WASTE AS LOW COST ADSORBENT

Dyes are widely used in industries such as textiles, rubber, plastics, printing, leather, cosmetics, to colour their products. As a result, they generate a considerable amount of coloured wastewater. Colour removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also mainly due to its visibility problem. Discharge of dye from wastewater into natural streams and rivers poses severe problems to the aquatic life, food chain and causes damage to the nature of the environment. Dyes absorb and reflect sunlight entering water and so can interfere with the growth of bacteria and affects photosynthesis in aquatic plants. The problems become greater due to the fact that the complex structures of the dyes remain ineffective in the presence of heat, light, microbes and even oxidizing agents that affects degradation of the dyes. Hence, these pose a serious threat to human health and water quality, there by becoming a matter of vital concern. There have been various promising techniques for the removal of dyes from wastewater. Different types of advanced methods are used for the degradation of the dyes. Aim of this project is degradation of dyes from industrial waste water using advanced methods.
