Raik Schönfeld, Managing Director, Blücher

Mr. Schönfeld, what reasons support adsorbents for the removal of pharmaceutical residues in drinking water?

“As opposed to ozonisation and UV treatment, adsorption is a very promising method since it produces no complex or possibly toxic decomposition products which must then be removed by adsorption. This treatment technology uses conventional activated carbons of various kinds and forms. However, performance is limited or even impossible with regard to the capacity or the kinetics of many types of pharmaceutical residue.

Saratech polymer based spherical activated carbons of Blücher have distinct advantages over conventional activated carbons. This is directly linked to the structure of pharmaceutical residues. The adsorbents are organic molecules with a complex structure and are frequently composed of polar functional groups, so they have better adsorbing properties than conventional carbons.“

Filtech 2013: Knowledge transfer between theory and practice

The world of filtration and separation will come to Wiesbaden/Germany for Filtech 2013 from 22 to 24 October 2013. The event will feature 300 exhibitors and their latest innovations and up-to-date filtration and separation technolgy on more than 8,000 m² exhition space – for example particle measurement and analysis systems as well as adhesive applicatios and speciality chemicals, composites filter media, cutting, welding and sewing equipment.

In addition to the fair a 3-day Conference presents the latest filtration research and the knowledge transfer between theory and practice. A programme with over 200 lectures from 37 countries gives a representative crosssection of the different procedures and appliances of separation technology. It features information in the field of „Solid-Liquid-Separation“ by filtration and sedimentation as well as „Air and Gas Cleaning“ by filtration, settling, electrostatic precipitation and scrubbing. Another theme of the conference is „Membrane Separation Technology“ in a wide range of sectors.
