Filtration in the future: Innovative filter media and their manufacture for air pollution control and fuel filtration

摘要

Edana, the international Association of Nonwovens Industries, have been hosting the FILTREX conference together with the accompanying industrial exhibition for the last 12 years. In autumn 2014, the general manager of Edana, Pierre Wiertz, welcomed more than 150 participants to Berlin. Admittedly, filter media only have a share of around 8% of total nonwoven industry sales, but have a growth rate of around 9% per year in Europe for all types of filter media, which is an outstanding share of the nonwovens. Two trends that have a significant influence on the global market for filter media were the main focus of the event. The first is the call for new requirements regarding fuel qualities and the new conditions stipulated in the environmental legislation, which require continuous further developments in the fuel filtration sector. The other covers the challenges presented by increasing urbanisation in many countries with regard to air pollution control and in fact, both apply to protection from emissions as well as for improving the air quality in indoor areas. The answers to these challenges are new filter media developments and production processes for air and liquid filtration.
