Phytoremediation.ppt
Phytoremediation is the process of using plants to remove contamination from soil or water. It involves using plants and their associated microorganisms in the rhizosphere to degrade, contain, or remove pollutants from the environment. Some key advantages are that it is a cost-effective, environmentally friendly way to remediate large areas of contaminated land. However, it is limited to sites with lower contaminant concentrations and works more slowly than conventional remediation methods. Common contaminants removed through phytoremediation include heavy metals, hydrocarbons, pesticides, and explosives. The process works through plants absorbing, degrading, or stabilizing pollutants in their tissues or the surrounding soil.

ABSTRACT- Wastewater treatment is a problem of grave concern in most developing countries. In the last two decades, there has been a lot of research to develop appropriate technologies to alleviate pollution in water resources. Efficient wastewater treatments through conventional methods are expensive and difficult to get optimum results. Currently, phytoremediation is an effective and affordable solution used to remediate toxic pollutants from aquatic ecosystems. The review describes various aquatic plants, which have high potential to remove heavy metals from wastewater. Key-words- Water pollution, Heavy metals, Phytoremediation, Aquatic plants, Wastewater treatmentLandfills
Landfills are commonly used for waste disposal by burying waste materials. Landfills can cause environmental impacts such as wildlife injuries, pollution of surrounding areas, and production of methane gas as organic waste decays. When constructing landfills, liners are installed and waste is buried in defined cells. Leachate, a liquid containing organic compounds and chemicals, is produced as waste decomposes and mixes with rainwater. Gases produced in landfills include methane, carbon dioxide, nitrogen, and ammonia, with methane being flammable. All landfills will eventually leak as the materials degrade over time.

Industrial pollution can cause various types of pollution including air, water, soil, noise, thermal and radioactive pollution. The document discusses the causes and effects of each type of pollution. The major causes are emissions from industries, vehicles, mining, improper waste disposal, and agricultural activities. The effects include damage to the environment, health impacts like respiratory illnesses and hearing loss, as well as impacts on wildlife. Various control methods are mentioned like using cleaner energies, proper waste treatment, and increasing awareness.
Bioremediation Of Heavy Metals (Copper)
Bioremediation uses microorganisms or plants to remove pollutants from the environment. There are two main types - in situ treats pollutants on site, while ex situ removes pollutants to off-site facilities. Examples of in situ techniques include bioventing, biosparging, and in situ biodegradation which supply oxygen and nutrients to stimulate bacteria. Ex situ methods include slurry and aqueous reactors which process contaminated materials in a contained system. Bioremediation can degrade pollutants like copper but has limitations such as environmental constraints and long treatment time.
Phytoremediation
The document discusses the topic of phytoremediation, which uses plants to remove pollutants from soil, water, and air. It defines phytoremediation and describes the various processes involved like phytoextraction and rhizofiltration. Examples are given of plants commonly used in phytoremediation like Indian mustard, willow, and sunflower. While phytoremediation has advantages of being low-cost and using solar energy, it also has limitations like being a slower process than traditional techniques and potential contamination of the food chain. The document concludes that phytoremediation is still evolving but has potential to help curb toxic pollution.
Environmental chemistry
The document discusses various topics related to soil pollution and waste management. It defines soil pollution and lists its main causes as waste dumping, mining, agrochemicals, and urbanization. It then discusses strategies for controlling environmental damage and different methods of waste management, highlighting concepts like the waste hierarchy and polluter pays principle. Finally, it defines green chemistry and provides examples of its applications in areas like dry cleaning, paper bleaching, and chemical synthesis.

This study investigated the efficacy of Typha latifolia (cattail) in removing pollutants from contaminated soil and water near an industrial area through phytoremediation. Samples were collected weekly from a wetland planted with T. latifolia and analyzed, finding a 12% reduction in chromium levels. Graphs showed a gradual reduction of pollutants over time in soil and water near the plants. T. latifolia also demonstrated an ability to bioaccumulate pollutants, validating its potential for large-scale sustainable remediation while highlighting the need to understand bioaccumulation dynamics.
Treatment of industrial effluent
This document summarizes a study on using the aquatic plant Eichhornia crassipes (water hyacinth) to treat tannery effluent through phytoremediation. The study involved collecting tannery effluent samples, analyzing their physicochemical properties, treating the effluent with water hyacinth for 20 days, and re-analyzing the treated effluent. Key findings were that the water hyacinth significantly reduced parameters like pH, TDS, BOD, COD, and improved the overall quality of the effluent, demonstrating its potential for low-cost, effective phytoremediation of tannery wastewater.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Mine Waste Utilization
- 1. UNIVERSITY OF PETROLEUM AND ENERGY STUDIES,DEHRADUN PRESENTED BY, MOHD ANAS +91 9761103376 anas.mohd14@stu.upes.ac.in PROTOCOL AMBIENT
- 2. MINE WASTE UTILIZATION ABSTRACT In this case study we address and review the status of phytoremediation as a technology to reduce and control contaminated mine wastes. Several different approaches and different plant species are used to remove environmentally toxic metals from mine waste sites. Such approaches have the objective of restoring mining waste sites to human and animal use, or at least, to curtail or eliminate the off-site movement of toxic entities that potentially could reach humans. We conclude that Phytoremediation is a low cost and eco-friendly remedy for the treatment of heavy metal wastes in the environment.
- 5. What is phytoremediation? Phytoremediation –is defined as the use of green metal accumulating plants for removal of heavy metal from soil as well as water.
- 7. USES OF PHYTOREMEDIATION Remediation of different media: Air Soil,sediments. Ground water. Wastewater streams -industrial -agricultural -municipal,sewage.
- 9. Phytoextraction Plant roots uptake metal contaminants from the soil. Once the plants have grown and absorbed the metal pollutants they are harvested and disposed off safely
- 10. Phytodegradation Phytodegradation is also known as phytotransformation. It is the breakdown of contaminants taken by the plants.
- 11. Rhizofiltration It is concerned with the remediation of contaminated groundwater The contaminants are either adsorbed onto the root surface or are absorbed by the plant roots Chernobyl - sunflowers were grown in radioactively contaminated pools
- 12. Advantages of Phytoremediation Cost effective when compared to other more conventional methods. “nature” method, more aesthetically pleasing. minimal land disturbance. reduces potential for transport of contaminants by wind, reduces soil erosion hyperaccumulaters of contaminants mean a much smaller volume of toxic waste. multiple contaminants can be removed with the same plant.
- 13. Phytoremediation project(1997) Mississippi site Groundwater polluted with TNT pumped through constructed wetland. RESULTS: 95% reduction in TNT
- 14. Current status of phytoremediation 9 purely phytorem. Companies. 7 constructed wetland companies >40 consulting/engg. Companies that also do phytoremediation ~200 field projects -founded mostly by EPA,DOD,DOE -some commercial/joint projects
- 15. Our Recommendations for Indian Mines
- 16. CONCLUSION Phytoremediation , which makes use of vegetation to remove, detoxify, or stabilize persistent pollutants, is a green and environmentally-friendly tool for cleaning polluted soil and water. The advantage of high biomass productive and easy disposal makes plants most useful to remediate heavy metals on site. We conclude that Phytoremediation is a low cost and eco-friendly remedy for the treatment of heavy metals in the environment.
