Studies on Textile Industry Waste Water Using Saw Dust as a Low Cost Adsorbent
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 6
Abstract
The 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 saw dust was 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 saw dust 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 12.5g/l of wastewater, with an optimum contact time of 24 hours, 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 67% with an absorbance of 0.16, BOD too was reduced from 400mg/l to 300mg/l. also owing to the adsorption process several other parameter such as chloride, sulfate, iron, COD was also reduced considerably.
