What is ex situ soil remediation?

What is ex situ soil remediation?

Ex situ techniques involves the treatment of contaminated soil, away from the polluted site. Ex situ techniques involve land farming, biopile, windrow, soil washing, composting, bioreactor, ion exchange, adsorption/absorption, pyrolysis and ultrasound technology.

Which is ex situ bioremediation process?

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.

How ex situ and in situ bioremediation is performed?

It can be done in two ways: in situ or ex situ. 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.

What is in situ ex situ soil?

In situ refers to the on-site and it is used to describe methods carried out in the original place. On the other hand, ex situ refers to the off-site and it is used to describe the methods carried out away from the original place.

Is phytoremediation in situ or ex situ?

“Ex situ” and “in situ” are two possible remediating options. Ex situ remediation involves excavation of polluted soil followed by treatment, rendering it an expensive cleanup method. In situ phytoremediation is the onsite contaminant removal through plant uptake in a cost-effective and eco-friendly way.

How many types of in situ bioremediation are there?

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 is in situ bioremediation example?

These include Natural Attenuation, Composting, Bioslurping, Bioventing, Biosparging and microbe assisted Phytoremediation to name a few. All these techniques follow any one or more of the three main strategies used in In situ bioremediation namely Bioattenuation, Biostimulation and Bioaugmentation.

Is an example of ex situ soil?

This soil is formed when the agents of erosion deposit sediment at a place. This soil is formed when the parent rock is broken into small fragments. This soil is formed far away from its parent rock. For example black soil, desert soil etc.

What is the other name of ex situ soil?

Alluvial soil exists as ex situ soil.
