APU® Acid Purification Unit
•Datasheet: APU Acid Purification Unit
Eco-Tec's APU® system has become a standard in several metal processing industries including aluminium anodizing and stainless steel pickling. Hundreds of Eco-Tec APU® systems are installed in over forty different countries around the world. Today, almost every new factory built for these operations incorporates an APU® due to its highly efficient and fully automated method to purify and recover inorganic acids.
Why Use an APU®?
Large amounts of mineral acids—including sulphuric, hydrochloric, nitric, phosphoric and hydrofluoric—are used in both the primary extraction of metals as well as their subsequent finishing and treatment processes in industries such as steel pickling, aluminum anodizing, and etching. Eventually these acid baths become spent due to high metal content and need to be replaced even though there is still an appreciable quantity of free acid that can be used.
The APU® addresses this issue by continuously purifying these acid solutions of the metal contaminants. The result is a reduction in acid purchases, neutralization costs, bath dumping and reformulation. The benefit is a consistent and predictable bath operation at all times, with minimal waste.
