Removal of Heavy Metals from Waste Water Using Water Hyacinth
-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...
متن کاملPhytoremediation of industrial mines wastewater using water hyacinth
The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastew...
متن کاملNitrogen Phytoremediation by Water Hyacinth (Eichhornia crassipes (Mart.) Solms)
The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm. A modified Hoagland solution was added to ponds containing water hyacinths which were rated and measured weekly for 4 weeks. The hyacinths accounted for 60–85% of the N removed from solution. Net producti...
متن کاملPhytoremediation of Textile Waste Water Using Potential Wetland Plant: Eco Sustainable Approach
One of the major problems encountered in the textile industry is the production of large volumes of highly coloured wastewater. The textile industries daily discharge million litres of untreated effluents in the form of wastewater into public drains that eventually empty into rivers. They cause serious health hazard. Textile wastewater also contains substantial pollution loads which increase th...
متن کاملHeavy Metal Phytoremediation by Water Hyacinth at Constructed Wetlands in Taiwan
The ability of water hyacinth ( Eichhornia crassipes Mart. Solms.) to absorb and translocate cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), and nickel (Ni) was studied in the Erh-Chung wetlands. Translocation ability was defined as the quantity of Cu, Pb, Cd, Ni, and Zn translocated in the plant’s tissues, and was expressed as a root/shoot ratio. The ratio results were in the order of Cu>Pb>C...
