Brush pickling is a commonly used method to clean welds and remove oxides from stainless steel. Therefore, it’s important to understand how to handle the rinse water.
It’s not permitted to discharge rinse water after brush pickling into the municipal sewer system or into nature. According to the Environmental Code and the EU’s chemical regulation (REACH), the rinse water must be properly managed.
We recommend reading the Guidelines for the discharge of industrial and other wastewater published by Tekniska Verken in Linköping in collaboration with Eskilstuna, Strängnäs, Gästrike Vatten, Karlstad, Linköping, Norrköping, Uppsala, Västerås, and Örebro municipalities. Svenskt Vatten also provides additional information about the Environmental Code and the chemical regulation.
