Enhancing Efficiency and Sustainability with Scanacon’s Acid Recovery Systems

Image
In today’s metal processing industries, efficiency, sustainability, and cost savings are more important than ever. From stainless steel to titanium and specialty alloys, pickling and acid-based surface treatments are essential steps in the manufacturing process. However, managing spent acids and reducing chemical waste present significant challenges. That’s where Scanacon’s advanced acid recovery systems come in—offering a reliable, eco-friendly, and cost-effective solution for reclaiming and reusing valuable process acids. Why Acid Recovery Matters Traditional metal pickling processes consume large volumes of strong acids such as hydrochloric, nitric, or hydrofluoric acid. Over time, these acids become contaminated with dissolved metals, reducing their effectiveness and increasing the frequency of disposal. This not only leads to higher operating costs due to chemical replenishment but also creates environmental concerns linked to hazardous waste management. Implementing an acid r...

An Overview of Stainless Steel Pickling

Image
Steel pickling is a kind of acid pickling done for surface treatment. Strong acids are used for this purpose. This treatment changes the outer layer of steel. As a consequence, the steel becomes clean, smooth, and highly resistant to corrosion. Pickling is a common process to achieve or restore the shine and brightness of the surface. This explains why stainless steel is composed of at least 10.5% chromium. This component forms a protective passivation layer that keeps the steel surface immune to air or moisture. Why Steel Pickling? Let us now study why steel or stainless steel should be pickled. Pickling is done to season the surface to make it highly corrosion-resistant. The outer surface of the material usually gets affected during the manufacturing process. As a result, the output often gets visible damage or might contain significant impurities. The types of damages and impurities are listed below: Formation of scale layers during heat treatment Formation of annealing colors duri...
