Hydrocarbons are harmful materials which can have serious consequences if an intervention is not implemented quickly.
Hydrocarbon contamination can be accidental or deliberate because, despite the fact that it is a fairly dangerous material, it can also have advantages, especially on the agricultural and industrial levels. It is then necessary to carry out a depollution in order to remove them and this action must be done with care by a professional.
What Does A Hydrocarbon Depollution Consist Of?
Hydrocarbon decontamination is a process consisting in cleaning up soil or sites polluted by hydrocarbons in order to reuse them. It is also a process that is aimed at ponds or lakes that have been polluted in order to make it healthy and comfortable for those who will have access to it.
The most common cause is that for ponds and lakes, as they are more sensitive to contamination. However, it can also happen that the soil is contaminated and the oil will therefore impair the fertility of the soil.
The Different Depollution Methods
According to the analysis started by the professional, he will judge the most suitable method for eliminating the presence of hydrocarbon.
He will examine the case according to the importance of contamination, the number of hydrocarbons that are present, their nature, and that of the soil. In short, a complete analysis of the site must be carried out beforehand to identify the appropriate clean-up procedures.
· In case the analysis proves the presence of volatile hydrocarbons, the process is simpler since it is a biodegradable material. They are easily eliminated by aeration and ventilation of the infected soil.
· On the other hand, if the expert detects heavier hydrocarbons, specific installations and equipment may be necessary. An excavation or biological or chemical processes will be fundamental to carry out the decontamination.
These steps can be done either outside the site, on the site or in situ, that is to say in its natural environment.
Pumping And Treatment
For a depollution to be complete, it is essential to do a pumping. Here, it will not be a question of using a truck or a cistern, but small equipment to pump groundwater. The expert will use a submersible pump or a vacuum pump for the contaminated parts. For the treatment, it is done gradually especially when it comes to water.
Depollution By Biological Processes
There are several types of biological remediation processes such as photo remediation. The latter is based on the use of nature and plant resources. Professionals don’t use it a lot because it heals slowly although some herbs have been shown to have strengths that can help with depollution.
Note that the plant or plant will act as a miracle remedy by emitting a substance that contributes to the degradation of hydrocarbons.
Depollution By Physicochemical Processes
It is rather in this direction that the professionals of pollution control are heading because these are chemical processes have been the subject of a physical test and have more value in their eyes. In a nutshell, this method will consist of injecting gas or liquid into the contaminated
soil. Subsequently, extraction is made by aspiration.
Other Means Of Pollution Control
Depending on the site assessment that has been carried out by the professional, there may be gentler and simpler ways for oil remediation. But in the event that the situation turns out to be more difficult or more sensitive, other methods, apart from those mentioned above, can help.
Biostimulation, in situ oxidation … There are many techniques, but the most common is the use of physicochemical products.
Why call on a professional for depollution?
The learning we had at school about the soil and its surroundings are not enough to master pollution control. Indeed, even just at the site assessment level, it is necessary to have in-depth knowledge to draw up the plan of attack that will suit the situation.
A professional will have the skills and qualities required to do the job without fail and without the contamination spreading elsewhere. In addition, you will have an opportunity to have advice in order to prevent the case from happening again.
