Eichhornia crassipes (Mart.) Solm: A biotic resource for waste water treatment
Keywords:Eichhornia crassipes, Physico-chemical parameter; trans-Yamuna regions; biotic resource; conventional wastewater treatment facility
The present study was conducted on effectiveness of E. crasssipes (water hyacinth) on physico- chemical parameters along with heavy metal removal from the waste water bodies present naturally in the trans-Yamuna regions of Allahabad, India during two seasons i.e., winter (November to February, 2011) and rainy (July to October, 2012). Results reveals that water hyacinth can be biotic resource which are useful in waste water treatment by altering the physico-chemical environment(DO increases with decrease in BOD and COD) of the water along with the reduction in the concentration of toxic heavy metals(Fe2+,Zn2+ and Cr6+)showing its highest pollution reducing capacity.The water hyacinth hold promise as a natural water purification system, which could be established at a fraction of the cost of a conventional wastewater treatment facility.
