Contribution to my article, Air Sparging (Draft)

[edit]

For my article, the add-ons I plan to put into the article will be pictures and plants that have been used for air sparging. Although, I did not intentionally want to do this article, I will try the best of my ability to put in information from scholarly articles I collect that will best be put in to let others know more about Air Sparging. Of course, reading the articles will help me with my analyses, so the contribution I will put in will in my own words with citations of where I got the information from.

So here are the bibliography that I'm planning to use for the articles so far:

Lead Section for Air Sparging So for the sections I will be adding to "Air Sparging" here are the types of information that will be shown:

  • The first start of the introduction for the Air Sparging will be changed generally with more facts being added
  • So air sparging, as I had taken a look at my sources, is the dissolving treatment of organic compounds founded in the late 1980's. As part of the remediation technology, it is used to injection air pressure in to the organic, saturated soils. The injection of air moves all water in creation of the porosity filled with are that will then rid of any dissolved VOCs and placing air into the groundwater. All of these steps will form an enhanced groundwater and saturated zones. Air Sparging has been used to correct errors to petroleum hydrocarbons and chlorinated solvents.
  • Improvement- So with the article lacking content, these are some of the ideas that will be added as contributions to Air Sparging:
#How Air sparging is beneficial to the society and people
#What is the explanation to the method and what subject does it fall under
#Possible Research
#Specific Mechanism of Air Sparging
#Companies that may be responsible for this method, like EPA.

So far these are the ideas for the article. More research is being conducted for ideas to add into Air Sparging.

Methods and Treatment

[edit]

https://en.wikipedia.org/wiki/Air_sparging In the form of extraction, the Soil vapor Extraction (SVE) are involved with numerous extractions that can run through contaminated soil to a point above the water table, that has to be at least 3 feet deep beneath the ground surface. Any equipments such as a pump or blower can be attached to the wells which then creates a vacuum and pulling the air and vapors in the soil and above the well to the ground surfaces for an approach. In order for the vacuum to avoid pulling the air from above into the system, the ground has to be paved with a tarp, which is a sheet to protect the ground. With air being pulled in is the means of reducing efficiency and accuracy of the cleanup process The tarp is used to protect vapors from being flown away off the ground to the air above it. [1] As for air sparging, it involves many drilling methods for injecting wells into the groundwater-soaked soil below the water table. On the surface, the air compressor pumps air underground through the wells. The air bubbles that comes out carries with it some contaminant vapors, coming towards the soil above the water table as it goes through water. As air and vapor are mixed together, they can be pulled out of the round and the Soil vapor Extraction are used for treatment.

In part of the treatment for Air sparging, the off-gases (referred as contaminated vapors and extraction of air) are used to rid any harmful levels of contamination. [2] For example, arsenic-contaminated groundwater were treated by air sparging and what the treatment does is remove arsenic at certain percentage using solution of iron and arsenic only at a molar ratio of 2. The treatment through air sparging is beneficial as groundwater contains high amounts of of dissolved iron, which contains the theoretical capacity for the treatment. [3]
