Remediation services

Complex land remediation projects involving multiple companies require simple, adaptable, and rapid purification solutions. Desotec’s mobile filtration services are ideal for short and long-term use, purifying air emissions and polluted groundwater effectively and sustainably so your soil remediation project can proceed on track.

Remediating contaminated land: a major challenge

Worldwide, former industrial sites are being earmarked for new building projects. However, the legacy of industrial activity, such as oil spills, often means that the land requires remediation first.

Legislation is generally becoming stricter. In many countries, construction companies must now treat any components they find. This holds up complex building projects until a rapid remediation solution is installed.

Desotec has the answers, supplying contractors with mobile sustainable filtration solutions to treat air emissions or contaminated groundwater associated with soil remediation.

Most unwanted components at brownfield sites are organic, which are easily treated with Desotec activated carbon filtration. They include mineral oils, volatile organic compounds (VOCs), benzene, toluene, ethylbenzene, and xylene (BTEX), adsorbable organic halides (AOX), and persistent organic pollutants (POPs) such as per- and polyfluoroalkyl substances (PFAS).


Purifying air emissions from land remediation

Desotec has a range of filters to handle the different flow rates and concentrations resulting from types of soil remediation processes. Where soil is excavated for ex-situ treatment, our filters may be installed at tents to treat emissions released by digging. They are a cost-effective way to handle large flow rates and are designed to allow for a low pressure drop, thus saving energy. A different filter model may be installed at the treatment facility itself to handle lower flow rates but far higher concentrations.

Vapour extraction processes may also take place in-situ, e.g., for contaminated land at a site still in use. The ground is treated thermally to turn the components into gases, producing very high concentrations which used to be hard to treat. Desotec rose to the challenge, developing its AIRCON HC-XL filter especially for this purpose.

Purifying the land and groundwater from past industrial activity is essential for creating a cleaner environment for future generations. Desotec is here to help, supplying sustainable mobile activated carbon filtration solutions which complement site remediation techniques.

Remediation of groundwater contamination for a cleaner environment

Where groundwater requires purification, pump-and-treat techniques are widely used. Groundwater is pumped to the surface, treated, then either injected back into the soil or discharged. Underground, components are contained hydraulically to preserve the surrounding land.

Desotec provides mobile water filters to treat the pumped-up polluted groundwater. They’re capable of handling large flow rates and varying concentrations of components. Activated carbon adsorbs the contaminants, allowing for the safe return or disposal of the groundwater.

How we help you

Desotec sustainable mobile filtration solutions

Desotec’s full-service solutions take the pressure off busy construction companies. Our filters are mobile, plug-and-play, and supplied on a rental basis, making them ideal for short-term or urgent purification needs.

With a small footprint, our installations fit into crowded sites. We have also developed filter safety features for usage where concentrations of components are high, protecting workers and equipment.

Desotec handles all filtration waste away from your site, destroying all components. Most spent carbon can be reactivated, boosting your company’s sustainability and helping you contribute to build a safer and greener construction sector.

Desotec’s expertise helped us with a soil and groundwater contamination issue. Their remediation knowledge was detrimental to make it a successful project.
