In July 2023, LAT Nitrogen Linz, in collaboration with Casale melamine process specialists, successfully completed the commissioning and start-up of a new melamine wastewater treatment plant for their production site based in Linz (Austria).

This plant has the aim to treat wastewaters coming from an LP-technology based melamine plant and from an HP-technology based melamine plant. Designed to comply with stringent environmental limits, the plant largely achieves the targets allowing to reduce emissions by several orders of magnitude.

Designed by Casale on the basis of the thermal decomposition of melamine and its related compounds followed by an ammonia stripping stage, the plant relies on a robust and reliable process scheme and is able to produce deep-cleaned water recovering valuable chemicals as an ammonium carbonate solution.
