Carbonology

Biofuel production is flourishing in Europe, thanks to increasing environmental awareness and EU incentives. However, the raw material usually contains contaminants that must be treated to avoid their release into the natural environment. DESOTEC supplies activated carbon filtration solutions to...

What are VOCs? The abbreviation VOCs stands for ‘ Volatile Organic Compounds ’. They are organic chemicals with a high vapour pressure at room temperature. An easier statement to comprehend: these components have a low boiling point which means that they evaporate quickly . An example is acetone,...

What does the abbreviation COD stand for? The abbreviation COD stands for ‘ Chemical Oxygen Demand ’. This value gives the amount of oxygen that would be required to fully oxidise (almost) all organic compounds. This is a measure to quantify the amount of organics in water and is most often used to...

DESOTEC works with partners around Europe on designing and implementing solutions for contamination issues in a wide variety of sectors. In this case, our expertise in waste management and logistics was as crucial as our activated carbon filtration technology in solving a 1,2-DCE pollution problem...

Companies across Europe are increasingly putting sustainability principles at the heart of their business models and seeking new ways to reduce their environmental impact. Yet cost-effectiveness is also a concern, with companies understandably reluctant to make major investments where only a...

In a harbour in the Nordics, a DESOTEC filter is in the process of treating 50 000 - 60 000 m³ of water from a subterranean rock cavern: enough to fill 24 Olympic-sized swimming pools. The activated carbon filter is successfully removing a range of oil-derived pollutants so the water is safe to be...

While DESOTEC filters are usually supplied on a ‘plug-and-play’ basis, our projects team can also provide all-in solutions to meet major clients’ filtration requirements. Our team has the engineering, mechanical and electrical expertise to design and install a complete system to remove VOCs, odours...

Bitumen is widely used as a roofing material, especially for flat roofs. Made from crude oil, it is valued for its weather-proof sealant properties. However, when bitumen is heated to liquid form during the production process it releases volatile organic compounds (VOC) such as hydrocarbons, which...

What is the difference between biogas and biomethane? Biogas is produced via anaerobic digestion by micro-organisms and is a mixture of CO2 and CH4 . Biomethane is biogas that has been upgraded to a high-qualitative gas with minimum 96% CH4. While biogas is most common used in combined heat and...

Wastewater treatment plants (WWTPs) are vital components of our infrastructure – yet they often create odour nuisance for those living nearby. In this article we will discuss common problems and effective solutions to remove odorous components from emissions. The problem WWTPs often produce...
