The Different Types Of Environmental Remediation Technologies
Not everyone knows what environmental remediation technology is and what it does. It’s not exactly what you talk about with your friends in your spare time. And even if you talk about it, people will just label you boring. But environmental remediation technology is a very important and timely topic that deserves further exposure.
Environmental cleanup is the branch of science that deals with cleaning environmental media. It is like surface water, sediment, groundwater, and soil from harmful pollutants and pollution.
Why is environmental remediation technology put into practice? Because it is for the general benefit of human health. A cleaner environment means a better life for all its inhabitants, including humans. This is the main reason why it should attract more public attention.
Environmental cleaning involves several different technologies in practice. Some of them are:
Agitation / stabilization
The solidification and stabilization method has proven to be one of the most robust and reliable technologies. Although recently it has triggered a number of problems related to durability and possible long-term side effects.
In addition, the use of solidification and stabilization emits CO2, which becomes a great obstacle to its widespread use.
o Coagulation: this decontamination technology involves adding reagents to the contaminated medium to contain contaminants and restrict the access of external agents
o Stabilization: this decontamination technology involves the addition of reagents to the contaminated media to the product components that are chemically stable.
Dredging or excavation
Dredging or excavation is one of the most basic types of remediation technology technologies. Excavation is exactly what the name says. The simple process of transporting contaminate media like soil from the original site to a regulated landfill where it is treat. Excavation may also involve aeration of the contaminated environment when volatile organic compounds (VOCs) are present.
Surfactant Enhanced Aquifer Remediation technology (SEAR)
Surfactant Enhanced Aquifer Remediation technology, also known as SEAR. It is the process of injecting agents such as specialty surfactants or hydrocarbon reduction into the subsurface to augment and enhance the recovery of the persistent non-aqueous liquid phase, or NAPL.
This is a permanent and cost-effective response for contaminate sites that have been treat prior to the use of other remediation technology technologies, but have prove ineffective. SEAR is also a proven successful first step when using other multifaceted remediation technology technologies. Such as Soil Vapor Extraction (SVE), which enhance bioremediation technology or oxidation in situ.
Other types of more advanced remediation technology technologies include pump and treat, in-situ oxidation, and steam extraction from the soil.
