Etching and pickling baths: Maximizing efficiency and sustainability in metal finishing

Описание: In this insightful interview, we sit down with William Gower, VP Projects at emew, to explore the world of etching and pickling in metal finishing. Discover the differences between these processes, their role in achieving the desired surface finish, and their impact on metal products. Dive into the generation of pickling and etching wastewater, and learn about the challenges posed by the disposal of spent solutions. Explore the potential for on-site regeneration of these solutions, and uncover the economic case for metal recovery and acid regeneration versus traditional disposal methods. Join us as we delve into the fascinating realm of metal finishing and its sustainable future.
