Best Available Techniques

Reducing micro-pollutants in wastewater

The 1998 list of Best Available Techniques (BAT) for textile finishing has been completed with a BAT study to limit a number of micro-pollutants in wastewaters. This study, with the collaboration of Centexbel and Fedustria, gives a survey of the Best Available Techniques to reduce the emission of a number of micro-pollutants via the evacuation of wastewater.
The study is aimed at:

  • textile companies active in textile finishing and using brominated flame retardants (Deca-BDE, HBCD), antinomy trioxide (Sb2O3), perfluorine tensides (PFOS and PFOA), nonylphenols (NFn) and/or nonylphenolethoxylates (NFE)
  • textile companies confronted with the presence of polycyclic aromatic hydrocarbons (PAHs) in auxiliary products

The BAT to reduce the emission of abovementioned micro-pollutants through the wastewater evacuated by the textile industry are generally preventive and process-integrated measures, such as the BATs

  • to come to an agreement about the used chemicals with the suppliers of fabrics and yarns
  • to use as much as possible eco-friendly alternative chemicals for textile finishing
  • to collect used process baths containing Deca-BDE, HBCD, Sb2O3, PFOS and/or PFOA and evacuate it through a recognized processing company.

The BAT study has also induced the BAT Associated Emission Levels or BAT-AELs for the textile industry and introduced a proposal concerning the sector-related evacuation conditions.
The BAT study serves as input material in the European BAT revision of the textile industry and is available on the EMIS website.
