Soil Vapor Extraction – Environmental Remediation Technique

Environmental remediation is essential since it directly impacts the way we manage our natural environment. It is a branch of science concerned with the elimination of pollutants or environmental pollutants like sediment, surface water groundwater, as well as soil.

A different, but similar type of technology used for remediation is MPE or Multi-Phase Extraction that is utilized to treat groundwater and soil, but is different from SVE because both techniques employ different kinds of technology.

Soil extraction vapor is broken down into three distinct kinds:

  1. Granular activated Carbon – GAC, also known as Granular Activated Carbon (or GAC) is a technique used to filter water or air. GACs are typically found in kitchen sinks to filter tap water. They're not very effective at getting rid of heavy metals in the water, however.

  2. Thermal oxidation This is another type of technology, but equally effective. However, this technique has been criticized because it releases dioxins into air as exhaust gases.

  3. Vapor condensation Vapor condensation can be thought to be the most efficient treatment technology (off-gas) for large concentrations of streams of vapor. It is also called cryogenic cooling or compression. You can also search online to get more information about soil vapor extraction.

Soil Vapor Extraction: Environmental Remediation Technique

Environmental remediation is important because it directly affects our treatment of our natural surroundings. It is the branch of science that deals with the removal of contaminants or pollution from environmental media such as surface water, sediment, groundwater, and soil.

Remediation is a widely practiced principle around the world under various government agencies, each with its own series of regulatory requirements and precautions. You can also look for vapor intrusion studies via Andersen Integrated Services.

Some of the most common and well-known environmental remediation technologies are dredging and excavation, SEAR or surfactant enhanced aquifer remediation, pump and treat, stabilization and solidification, in situ oxidation, and others like bioremediation.

Soil Vapor Extraction

Soil vapor extraction is a type of remediation technology used for treating contaminated soil, as its name implies. Another similar but different type of remediation technology is the MPE or Multi-Phase Extraction, which is used for treating soil and groundwater but different from SVE in that both methods utilize different types of technologies.

Soil vapor extraction is broken up into three different types:

  1. Granular activated carbon – Granular activated carbon (or GAC) is a technology used as a filter for water or air. GACs are commonly seen in household sinks used for filtering tap water. It is not effective in filtering heavy metals from the water, though.
  2. Thermal oxidation – Thermal oxidation is another kind of technology, yet also effective. But this approach has since proven controversial since it releases dioxins into the atmosphere as exhaust gas.
  3. Vapor condensation – Vapor condensation is considered the most effective type of treatment technology around (off-gas) for high concentration vapor streams. This technology is also sometimes called cryogenic cooling and compression.
