Green and Eco-Friendly Treatment of Textile Wastewater by Using Azadirachta indica Leaf Extract Combined with a Silver Nitrate Solution

Abstract

The present study was conducted to treat textile industrial wastewater through the combination of green and synthetic solutions. Two case studies were applied for the treatment of wastewater. In the first case, discharged industrial effluent was reacted with Azadirachta Indica leaf extract solution for a 4 to 72 h retention time. After the reaction, some pollutants were treated but most required higher retention time and concentration of A. indica extract, which could be a potential adsorbent for wastewater treatment. In the second case, the discharged industrial effluent was reacted with A. indica solution with silver nitrate AgNO3 solution and was used as a treating agent for wastewater with a 4 to 72 h retention time. The second case was found to be better than the first case as it treated a greater number of pollutants. Moreover, treatment plant design feasibilities will be required for the application of findings of the present study on an industrial scale. This study can be useful to improve industrial estate’s environmental conditions for reducing pollution by industrial wastewater. There is also a need to raise environmental awareness regarding wastewater’s health effects in local communities.
