Among the various processes in the textile industry, dyeing process uses large volume of water for dyeing, fixing and washing processes. Thus, the wastewater generated from the textile processing industries contains suspended solids, high amount of dissolved solids, un-reacted dyestuffs (colour) and other auxiliary chemicals that are used in the various stages of dyeing and processing. The conventional method of textile wastewater treatment consists of chemical coagulation, biological treatment followed by activated carbon adsorption. However, wastewater containing dyes is very difficult and complex to treat, since the dyes are recalcitrant organic molecules, resistant to aerobic digestion, and are stable to light, heat and oxidizing agents due to their molecular structure and size. Adsorption techniques have gained popularity in recent years because of their proven efficiency in the removal of pollutants from Textile industry effluents which are too stable for conventional treatment methods. Apart from the high quality product obtained, the processes have proved economically feasible. In most of the textile processing industries, activated carbon is generally used as aadsorbent to remove dyes in wastewater due to its excellent adsorption ability. For the study presented here Activated carbon (Commercial), Charcoal (Cashew-nut shell) and Charcoal (Wood) were used as an adsorbent. The experimental investigations have been made to find the effect of concentration of dye on adsorption rate of different adsorbents and to find the inexpensive alternative adsorbents in order to minimize the cost of effluent treatment from Textile industry.

Most of the industries such as textile, paper, carpet, and printing use dyes and pigments to color their products. Due to their good solubility, synthetic dyes are common water pollutants and they may frequently be found in trace quantities in industrial wastewater. However, the discharge of dye-bearing wastewater into natural streams and rivers possess a severe problem, as dyes impart toxicity to aquatic life and are damaging the aesthetic nature of the environment. However, wastewater containing dyes is very difficult to treat, since the dyes are recalcitrant organic molecules, resistant to aerobic digestion, and are stable to light, heat and oxidizing agents due to their structure and molecular size. Adsorption techniques have gained favor in recent years because of their proven efficiency in the removal of pollutants from effluents too stable for conventional treatment methods.

In many textile processing industries, activated carbon is used as a sorbent to remove dyes in wastewater due to its excellent adsorption ability. For the study presented here Activated carbon (Commercial), Charcoal (Cashew-nut shell) and Charcoal (Wood) were used as an adsorbent. The experimental investigations have been made to find the effect of various parameters on the change in concentration of dye and to find the inexpensive alternative adsorbents in order to decrease the cost of treatment.
