Cost Effective Wastewater Treatment by Natural Adsorbent

Abstract

Today the major environmental concern is the water pollution due to the discharge of colored wastewater from textile industries. This colored wastewater is harmful to human, aquatic life, and ecological sustenance. It is essential to treat this wastewater before discharge into the environment. In this study, we used one of the world's worst weeds water hyacinth (Eichhornia crassipes) as an adsorbent. The combination of water hyacinth with coal and bricks can minimize the number of different contaminants present in the wastewater. The textile wastewater was treated with water hyacinth, coal and bricks and then filtered. The study revealed that after treatment of wastewater with water hyacinth, coal and brick, the value of all parameters was reduced than the untreated wastewater. The results indicate that the water hyacinth have a high possibility of being used as a cheap and efficient adsorbent to remove the color and organic contaminants from wastewater of textile industry.
