Purification with mobile activated carbon filters

Treatment of chemicals

Plants manufacture products. Certain reactions may occur during the manufacturing process that can give rise to undesirable contamination of the end-product. On the other hand, certain products may fail to meet the requirements of the manufacturing process. Malfunctions can also occur during the manufacturing process, which will result in a batch of products failing to meet specification. Moreover, certain products acquire increased sales value if they have a certain degree of purity, which can be achieved thanks to activated carbon.

All these examples are areas of application for DESOTEC’s activated carbon-based mobile filter systems.

It may involve organic or inorganic acids, with an end-result that meets food or industrial quality. All kinds of oil are suitable for activated carbon treatment, as are undesirable colours and odours, dioxins in edible oils or a fatty acid.
DESOTEC has developed a range of packages for all these applications, including examples such as the high pressure-resistant mobile filters for treating hydrochloric acid (HCl), which is made entirely of plastic.



DESOTEC offers different types of activated carbon for chemicals treatment:

  • Granular activated carbon of different qualities for the removal of dissolved (organic) pollutions.
  • Powdered activated carbon to be dosed in the liquid chemical to be treated.

Specifically for the treatment of chemicals, DESOTEC developed a fleet of mobile filters processing liquid flows to above 100m³/h per filter.

The use of mobile filters offers several advantages to the user:

  • An easy to use and compact solution.
  • Plug-and-Play.
  • Small and compact units designed to treat a broad range of flows and concentrations.
  • The filters are offered with daily rental contracts. No capex facility is needed.
  • On site representative piloting.
  • No maintenance cost.
  • Continuous new developments and improvements.

DESOTEC offers recycling solutions for spent activated carbon coming from chemicals in its own furnaces and other recovery facilities.
