Circular Purification Power
We help our customers operate in a more sustainable way. Using our filter systems, we capture their pollutants using activated carbon, a natural product that acts like a sponge, sucking up contaminants.
Once saturated with captured pollutants, the activated carbon is taken to our facility in Roeselare, Belgium. Here, the contamination is completely destroyed, and the activated carbon is recycled, while creating a new product of the waste and creating energy which is re-used for the high quality reactivation process of the carbon. Only water vapour is emitted from our chimneys.
See how we do it
Analysis of the purification need
DESOTEC engineers work with each of our customers to completely comprehend the purification need they are facing. If required, lab tests are done to simulate the problem setting and, once the problem is completely clear, the most optimal solution is put forward.
We don’t stop until we’re rock solid that the purification need can be completely solved.
Deployment and installation of mobile filter
The mobile filter, filled with the most optimal activated carbon type, is delivered to the site of the customer and connected. The purification process can start immediately. Plug-and-play!
Filter and adsorb pollutants
The filter is now in use to purify air or other gasses and liquids such as water. Each filter holds very carefully selected activated carbon, a natural product which acts as a sponge and adsorbs any contaminant present. Once the filter is saturated, the filter is immediately exchanged for a new one. Changes in the customers’ production process are quickly and easily met by optimizing the filters.
This ensures that the customer can fully focus on his own core business, and leave the rest up to us.
Recycle and reactivate the saturated carbon
The saturated filter is sealed off and safely transported back to a DESOTEC facility, ensuring that there is no waste handling on site of the customer. The saturated carbon is safely taken out and recycled via a thermal reactivation process and can be reused.
Through decades of innovation and investments, DESOTEC is constantly maximizing the share of activated carbon that is re-used, contributing to circular use of the activated carbon.
Fully neutralise all pollutants
State of the art processes and flue gas treatment systems ensure that all contamination is completely destroyed and neutralized, and every useful residue product is recuperated. This pushes our operations to 100% circularity, not losing any resources!
Our entire installations and their emissions comply with National and European legislation, even more: they are under continuous monitoring which ensures that only harmless water vapor is seen at the exit of the chimney.
We also create new energy during the recycling process, which is re-used for our high quality reactivation process.
