It is a fact that our world today is faced with challenges in protecting our environment. Several solutions are researched, tried and implemented by experts in the government, private sectors and organizations whose goal is in the preservation of the environment. Among these methods is thermal desorption which is used to clean up soil that has been contaminated with hazardous chemicals and are removed from the soil. Simply put, thermal desorption is a way contaminated soils are treated from hazardous wastes.
In cleaning contaminated contaminated soils, thermal desorption used the remediation method where heat vaporizes the contaminants, specifically for contaminants that are volatile. Among the materials that can be subjected to these are organic wastes like hydrocarbons, oil refining wastes, coal tar wastes, wood-treating wastes, fuels, synthetic rubber processing wastes, pesticides, paint wastes and so on.
The application of heat on the contaminated soils would allow wastes to reach low boiling points thus forcing it to turn into vapor and then collected and treated again in a unit for gas treatment. The objective then to allow the soil to be used again for other purposes without the fear of contamination is attained. In landfill space, this method is advantageous because it can be preserved instead of being transferred to another area without the solution of the contamination.
The techniques involved in purifying and revitalizing the soil is addressed as soil remediation, which is part of environmental remediation in the broader sense. The main goal of this process or remediation efforts is to reduce the concentration of contaminants within the soil, thus making the soil more suitable for use with the risk of the environment.
Actually, several methods can be used when dealing with soil contamination, where some ways could be effective than the others. When a method is selected it is advisable to know how it is going to impact the living things in the surrounding area where the method will be applied. It is also good to know the nature of the soil contamination to make the process successful. Sometimes an area has to undergo several soil remediation processes in order to take care of different contaminants. Sometimes, soil remediation can purify extracted liquid by eliminating ground water that is contaminated under a process called pump and treat. Here, there is soil extraction and then contaminants are removed through filtering and the soil is returned afterwards to its original area.
Today, more and newer methods that are effective are being developed, thankfully to the present technology that is fast advancing. Many of these efforts for soil remediation are under the levels of the national government guidance in order to make the soil suitable for dwellings, farms and wildlife habitat, with the removal of harmful contaminants. There are companies that are into green thermal desorption who can offer services in the process. Different countries are giving support to these efforts of remediation strategies. There are equipment manufactured by some companies that can be distributed worldwide to perform this process.
