  • Treatment of urea manufacturing facility effluent by Hopea odorata and Khaya ivorensis

    Phytoremediation is an environmentally friendly and sustainable alternative for treatment of nitrogen-enriched wastewaters. In this study, Ta-khian (Hopea odorata) and Lagos mahogany (Khaya ivorensis), two tropical timber plants, were investigated for their performances in treatment of urea manufacturing factory effluent with high nitrogen (N) content. Plant seedlings ...

  • Screening of few aquatic floating plants for chromium phytoremediation

    Phytoremediation process using hydrophytes emerges as an attractive scientific and engineering tool for the attenuation of metal pollution in the aquatic environment particularly in secondary and tertiary levels of wastewater treatment. The selection of appropriate plants on the basis of maximum uptake potential for engineering application of the process is the key factor. The present study deals ...

  • Phytoremediation of mercury using Eichhornia crassipes (Mart.) Solms

    Roots of Eichhornia crassipes were found to accumulate maximum content of mercury (92.21 μg g−1 dry wt) in the roots of plants treated with 1000 μg l−1 concentration of mercuric acetate on 14th day of treatment. The bioconcentration factor (BCF) was found to be highest for lowest mercury concentrations ...

  • Phytoremediation of chromium(VI)-laden waste by Eichhornia crassipes

    The aim of the present investigation is to develop a suitable phytoremediation technology for the procumbent removal of chromium(VI) in tannery wastewater. Water hyacinth species, Eichhornia crassipes, was chosen to remediate chromium from synthetic wastewater. Present study revealed 88% Cr(VI) removal in synthetic wastewater sample within 48 hours of the study at all concentrations ranging from ...

  • Coupling vermiremediation with phytoremediation technology to enhance the efficiency of reclamation of polluted marine sediments

    Contaminated (TPHs and heavy metals) dredged sediments from Livorno port (Italy) were biological treated using plants and earthworms. Sediments presented an asphyctic physical structure owing to the silt?clay granulometric composition, a high salty level and a low organic content. A meso-scale experiment was done utilising three different bioremediation treatments: a) plants (Paspalum vaginatum ...

  • Phytoremediation technology for wastewater treatment: high rate transpiration system

    High Rate Transpiration System (HRTS) is a well-designed land treatment system composed of ridges and furrows and well-controlled hydraulic loading of wastewater. The present case study describes long-term operating experience of zero discharge of pulp and paper mill wastewater, which is characterised by high BOD, COD, TDS and colour that poses disposal problems into water bodies and on land. The ...

  • Microbe-assisted phytoremediation approach for ecological restoration of zinc mine spoil dump

    Mining is one of the sectors that impacts air, water and soil pollution. The various environmental problems that are associated with mining activities are deforestation, removal of fertile topsoil, unstable slopes prone to sliding and erosion, siltation of water bodies due to wash off of mineral overburden dumps, air pollution due to discharge of dust and noise pollution. The most effective means ...

  • Zn and Cd hyperaccumulating characteristics of Picris divaricata Vant.

    A field investigation and a pot experiment were conducted to study the Zn and Cd accumulation in Picris divaricata Vant. Under natural conditions, the average Zn and Cd concentrations in shoot of P. divaricata were 5911 and 246 µg g−1 (DW), with the maxima of 18,339 and 585 µg g−1, respectively. Grown on a mixed soil for three months, P. divaricata accumulated up to 15,183 μg g−1 Zn and 364 µg ...

  • Pteris multifida Poir., a new arsenic hyperaccumulator: characteristics and potential

    This paper reports a new arsenic hyperaccumulator, Pteris multifida Poir, a fern that grows widely in the southeast of China. The results show that the average arsenic content in the fronds was 1144.78 mg/kg, with a highest value of 2061 mg/kg. The average arsenic content in the roots was 692.7 mg/kg, and the average bioconcentration factor was 1.2, with a highest value of 1.78. The average ...

  • Analysis of Hydrologic Data to Evaluate Phytoremediation System Performance

    Abstract A long-term environmental monitoring program is providing hydrologic data that demonstrates poplar trees are influencing groundwater flow at the J-Field site, Aberdeen Proving Ground, Maryland. Advanced data collection and analyses techniques have enabled researchers to construct a water budget for the study area and to estimate the amount of groundwater the trees are transpiring on a ...

  • Common Treatment Train for Inorganics

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for inorganics is illustrated below. Metal contaminated soil is treated using the combination of electrokinetics and phytoremediation. Electrokinetics is used to remove metals from deep soil and ground water. A low density direct current is applied to mobilize charged species, ...

  • Phytoremediation - II

    Introduction: Phytoremediation is a set of processes that uses plants to clean contamination in ground water and surface water. There are several ways plants can be used for the phytoremediation. These mechanisms include enhanced rhizosphere biodegradation, hydraulic control, phyto-degradation and phyto-volatilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Phytoremediation - I

    Introduction Phytoremediation is a process that uses plants to remove, transfer, stabilize, and destroy contaminants in soil and sediment. The mechanisms of phytoremediation include enhanced rhizosphere biodegradation, phyto-extraction (also called phyto-accumulation), phyto-degradation, and phyto-stabilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Phytoremediation - Technology Overview

    ABSTRACT Phytoremediation uses plants to cleanup contaminated soil and groundwater, taking advantage of plants' natural abilities to take up, accumulate, and/or degrade constituents of their soil and water environments. Results of research and development into ph ytoremediation processes and techniques report it to be applicable to a broad range of contaminants including numerous metals and ...
