What is ex-situ bioremediation explain its types with examples?
Ex-situ bioremediation is a biological process in which excavated soil is placed in a lined above-ground treatment area and aerated following processing to enhance the degradation of organic contaminants by the indigenous microbial population.
What are the types of in situ bioremediation?
Three different types of in situ bioremediation process are (i) bioattenuation/Natural Attenuation, which depends on the natural process of degradation, (ii) biostimulation where intentional stimulation of degradation of chemicals is achieved by addition of water, nutrient, electron donors or acceptors, and (iii) …
What are the methods of ex-situ bioremediation?
Ex situ techniques include: slurry & solid phase bioremediation: Solid-phase soil treatment processes include landfarming, soil biopiles, and composting. Slurry-phase soil treatment processes include the slurry phase bio-reactor.
How does in situ bioremediation differ from ex situ bioremediation?
In in situ bioremediation, contaminants are treated at the same site using biological systems. In ex situ bioremediation, contaminants are treated in some other place from the original site. This is the key difference between in situ and ex situ bioremediation.
Which of the following is an example of ex situ bioremediation?
Examples of ex situ processes include land treatment and composting. In these processes, soils are excavated, mixed with amendments, and operated in a manner that facili tates degradation of the contaminants of concern. Another way to divide the bioremediation field is based on additives to environmental media.
What is in situ and ex situ conservation?
The process of protecting an endangered plant or animal species in its natural habitat is commonly known as in situ conservation. On the other hand, ex situ conservation is the relocation of endangered or rare species from their natural habitats to protected areas equipped for their protection and preservation.
What is insitu and Exsitu technique in bioremediation?
Which of the following is a type of ex situ bioremediation?
What is insitu and Exsitu bioremediation?
What is in situ and ex situ remediation?
Ex situ remediation techniques involve removing the soil from the subsurface to treat it. In situ remediation techniques involve leaving the soil in its original place and bringing the biological mechanisms to the soil.
What are the different types of ex situ bioremediation techniques?
Ex situ techniques include: slurry & solid phase bioremediation: Solid-phase soil treatment processes include landfarming, soil biopiles, and composting. Slurry-phase soil treatment processes include the slurry phase bio-reactor.
What are the principles of ex-situ bioremediation?
Introduction/principles. Ex-situ bioremediation is a biological process in which excavated soil is placed in a lined above-ground treatment area and aerated following processing to enhance the degradation of organic contaminants by the indigenous microbial population.
What are the advantages and disadvantages of in situ bioremediation?
Advantages of in situ bioremediation: No need to excavate & transport soils – typically less expensive Can treat a large volume of soil at once. Causes less contaminants to be released than ex situ techniques
What are the methods of soil bioremediation?
Usually requires treatment of the contaminated soil before and, sometimes, after the actual bioremediation step. Ex situ techniques include: slurry & solid phase bioremediation: Solid-phase soil treatment processes include landfarming, soil biopiles, and composting. Slurry-phase soil treatment processes include the slurry phase bio-reactor.
