What is bioslurping?
What is bioslurping?
Bioslurping combines approaches of bioventing and vacuum-enhanced free-product recovery to address two separate contaminant media.
How does bioslurping work?
Bioslurping. Bioslurping combines elements of bioventing and vacuum-enhanced pumping of free-product to recover free-product from the groundwater and soil, and to bioremediate soils. The bioslurper system uses a “slurp” tube that extends into the free-product layer.
What is the process of Bioaugmentation?
Bioaugmentation is used to biodegrade specific soil and groundwater contaminants. It involves adding cultured microorganisms into the subsurface to biodegrade the desired contaminants. In many cases, these microorganisms are “specialists” in degrading specific target contaminants.
What are some remediation technologies?
In-situ technologies include but are not limited to: solidification and stabilization, soil vapor extraction, permeable reactive barriers, monitored natural attenuation, bioremediation-phytoremediation, chemical oxidation, steam-enhanced extraction and in situ thermal desorption and have been used extensively in the …
What is the difference between bioaugmentation and bioremediation?
As nouns the difference between bioremediation and bioaugmentation. is that bioremediation is (biochemistry) the use of biological organisms, usually microorganisms, to remove contaminants, especially from polluted water while bioaugmentation is the use of microorganisms to help decompose pollutants.
What do you need to know about bioslurping?
Bioslurping is a cost-effective in situ remedial technology that simultaneously accomplishes LNAPL removal and remediation of soil in the vadose (unsaturated) zone.
How is bioslurping used in hydrocarbon remediation?
Bioslurping is the adaptation and application of vacuum-enhanced dewatering technologies to remediate hydrocarbon-contaminated sites. Bioslurping utilizes elements of both, bioventing and free product recovery, to address two separate contaminant media.
How does bioslurping and vacuum enhanced free product recovery work?
Bioslurping combines approaches of bioventing and vacuum-enhanced free-product recovery t o address two separate contaminant media. Bioventing stimulates aerobic bioremediation of hydrocarbon-contaminated soils (recovers product) in the vadose zone – draws air into the soil while withdrawing soil-gas via the recovery well.
How is vapor extraction used in bioslurping technology?
V acuum extraction/recovery is used to remove free product along with some groundwater, vapor extraction is used to remove high volatility vapors from the vadose zone, and bioventing is used to enhance aerobic biodegradation in the vadose zone and capillary fringe.
