Carbonology

Smells emanating from slaughterhouses frequently lead to complaints from communities living nearby. The problem is often exacerbated by warmer weather in the spring or summer, when volatile organic compounds ( VOCs ) may become more odorous and more people will be outdoors. As legislation around...

What does the abbreviation AOX stand for? The abbreviation AOX stands for ‘Adsorbable Organic Halides’. This value gives the concentration of organic halogens, which are components containing chlorine, bromine or iodine, in a water sample. Increased levels are often related to pollution. What are...

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.
