Lanxess expands water treatment unit at Uerdingen pigment facility

24 October 2012

Lanxess has announced that it’s upgrading its water treatment capacities for the production of inorganic pigments. The company is investing €1.6M at its Krefeld-Uerdingen site in Germany to modernise and expand its water treatment unit at the world’s largest facility for the production of iron oxide and chrome oxide pigments. The expansion project will also increase the synthesising capacity for Bayferrox black and red pigments.

The new boiling vat measures five metres in diameter and nearly 11m in height and has an effective volume of 150m3. It will allow iron oxide pigments to be recovered from the process water.
