Abstract

Textile wastewater contains different colors which are harmful to the environment. The removal of dyes from effluent using adsorption process provides an attractive alternative treatment, especially if the adsorbant is inexpensive and readily available. In this present research paper natural adsorbant rice straw is used for removal of color from waste effluent of textile industry. The adsorbant prepared was employed for the removal of color at the different doses. The adsorbant was found to be capable of removing color from wastewater; the color removal capacity for rice straw was approximately 70% at normal pH and temperature. From the experimental investigations, the maximum color removal from the textile industry wastewater was obtained at an optimum adsorbant dosage of 2.5 g/l of wastewater, with an optimum contact time of 24 h, at room temperature. This result was higher than the results obtained by different process parameters for various adsorbants. It is found that the transmittance was found to be 72% with an absorbance of 0.15, BOD too was reduced from 400 mg/l to 200 mg/l. also owing to the adsorption process several other parameter such as chloride, sulfate, iron, COD was also reduced considerably.
