CO2 neutralises fibreous wastewater

The chemical company Solvay produces polyamide fibres at its site in Valence, southern France. The process generates alkaline wastewater. Solvay uses CO2 from Messer to neutralise them. Carbon dioxide forms carbonic acid in the liquid and thus lowers the pH value to the desired level. This is done in an environmentally friendly way and without forming additional salt, as opposed to the use of mineral acids. The high quality and highly resistant polyamide fibres are used, among other things, in the textile, furniture and automotive industries.
