Preliminary adsorption studies on textile industry waste water using Neem leaf powder as an adsorbant

In this present research paper natural adsorbant neem leaf was used for removal of colour from waste effluent of textile industry. The adsorbant prepared was employed for the removal of colour at the different doses. The adsorbant was found to be capable of removing colour from wastewater; the colour removal capacity for neem leaf was approximately 70% at normal pH and temperature. From the experimental investigations, the maximum colour removal from the textile industry wastewater was obtained at an optimum adsorbant dosage of 7.5g/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 72% with an absorbance of, BOD too was reduced from 400mg/l to 60mg/l. also owing to the adsorption process several other parameter such as chloride, sulfate, iron, COD was also reduced considerably.
