The tank respiration phenomenon (absorption of ambient humidity by liquid hydrocarbons) can generate a favourable environment for the development of bacteria, fungi and yeasts, with the following main consequences:

  • Feed circuit clogging
  • Emulsion formation
  • Corrosion

These problems may arise at any point in the distribution chain, from storage tank to motor vehicle. The treatment of this pollution requires the use of broad-spectrum biocides used for the prevention or treatment of these problems.


Our biocides can be used for treatment of both aqueous and organic phases:

  • Water at the bottom of hydrocarbon storage tanks (EB 301 W)
  • Petroleum distillates (EB 7301) 


Our products show spectacular results:

  • After a time of contact with the hydrocarbon of 6 hours, the number of living microorganisms is reduced by half.
  • Any trace of pollution disappears after about 36 hours.

Our biocides are sold exclusively to distribution professionals.
