Abstract

Textile industry processes are among the most environmentally unfriendly industrial processes, because they produce colour effluent that is heavily polluting the environment. Therefore, effluent from textile industry has to be treated before being discharged into the environment. In this study, experiments were performed to remove the colour from the textile industry wastewater using coconut coir pith powder as an adsorbent. The experiments were conducted by different process parameters like adsorbent dosage and agitation speed against the pH of 7 and initial concentration of 45 mg/L to reduce colour in a textile industry wastewater. The results showed that the maximum removal of colour occurred for the initial concentration of Acid Orange 10 dye of 11.125 mg/L in a textile industry wastewater found to be 96.3% and for the actual concentration of 45 mg/L in a textile industry wastewater was found to be 88.6%. Further, the experimental data were fitted well with pseudo second-order kinetic model than that of pseudo first-order kinetic model for colour by coconut coir pith powder in a textile industry wastewater. Thus, the selected coconut coir pith powder is used in removal the colour in a textile industry wastewater effectively.
