Tag: hydrofluoric acid

A new pickling process which does not require the use of hydrofluoric acid has been developed as part of a project funded by the EU through the LIFE programme (project code: 13 ENV/IT/000440). The process is beneficial in terms of both the environment and energy consumption. This article analyses the characteristics of the wastewater treatment process deriving from the new pickling process which eliminates once and for all the presence of hydrofluoric acid in the base solution.
