Abstract
Due to rapid growth in population, urbanization, most of the fresh water is consumed and the sewage water released from industries as well as from domestic households can discharged directly to water bodies which can cause severe problem to organisms. For this, appropriate management strategies should be applied which is cost-effective and easy to handle. These properties can be fulfilled by the Phytoremediation technology. The present study was aimed to assess the physico-chemical properties of untreated sewage water before and after the phytoremediation with Eichhornia crassipes. It is accumulator and tolerant species, which can be used to remove certain heavy metals. In this experiment, after phytoremediation process of 21 days, there was a significant decrease in various parameters such as pH, Electrical conductivity, Turbidity, Biochemical Oxygen Demand. Simultaneously, there is increase in Dissolved Oxygen (DO) as the contaminants reduced from sewage water. The phytoremediated sewage water meet the standards of Food and Agriculture organization of the United Nation (FAO). So, this recycled water can be utilized for irrigation purpose in agriculture field.
