Mahendra Pratap Choudhary, Sunil Sharma

Rapid population and economic growth especially in urban sectors is being experienced by most of the developing countries all over the world. As the ever-increasing population and urbanization are threatening the available water potential in many areas of the world, the treatment and disposal of wastewaters is becoming more and more crucial. Although water hyacinth (Eichhornia Crassipes) has proved to be a persistent and expensive aquatic weed problem in every part of world it has ever invaded, but at the same time, it is reported to have proved its value as a natural purifier. The objective of this study was to assess the viability of water hyacinth for treatment of industrial wastewater. The samples of industrial wastewater were treated with water hyacinth in the laboratory and it was found that water hyacinth is quite efficient in reducing the pollutional parameters such as BOD, COD, suspended solids, dissolved solids, heavy metals etc. The treated effluent is found suitable for reuse for non-potable reuses like industrial, agricultural or gardening purpose.
