What is biostimulation used for?
Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation. This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g. in the form of molasses).
What is Bioventing and Biosparging?
Bioventing is an in situ remediation method that enhances the biodegradation of contaminants (organic compounds) in the unsaturated soil zone. However, biosparging is not confined to the unsaturated zone, but rather extends remediation to the saturated zone of the soil matrix.
Where is Bioventing used?
Bioventing is most often used at sites with mid-weight petroleum products (i.e., diesel fuel and jet fuel), because lighter products (i.e., gasoline) tend to volatilize readily and can be removed more rapidly using SVE.
What are three examples of bioremediation?
3 Examples of Bioremediation
- Crime scene cleanup. Bioremediation in this sense involves the cleanup of blood and bodily fluids that can pose health risks such as hepatitis, HIV, and MRSA.
- The cleanup of contaminated soil.
- Oil spill cleanup.
What are the steps of bioremediation?
Bioremediation includes above-ground piling of dug polluted soil, followed by aeration and nutrient amendment to improve bioremediation by microbial metabolic activities. This technique comprises aeration, irrigation, nutrients, leachate collection and treatment bed systems.
What is the difference between biostimulation and bioaugmentation?
Bioaugmentation is the process of adding specific microorganisms to enhance the existing populations and promote biodegradation process while biostimulation is the process of adding electron acceptors, electron donors, or nutrients to stimulate naturally occurring microbial populations in the contaminated area.
What are the main requirements in process of Biosparging?
Bacterial removal of mineral oil and aromatic compounds To accommodate the bacteria of oxygen we therefore inject this into the soil and groundwater with injection filters. This direct supply of oxygen to the bacteria enhances their degradation capacity of the minerals oils and BTEXN.
