Removing impurities and recovering metal, separating sulfuric acid from dissolved metal salts in refineries, electrolyte bleed streams and leach streams.

One of the most widely used acid recycling systems in the world, the Eco-Tec Acid Purification Unit, APU®, continuously removes dissolved metals which contaminate acid baths. Since up to 70% of original sulfuric acid is lost in dumping, the APU® dramatically reduces acid and related waste treatment expenses. The APU® uses a resin sorption process and simple water wash to recover acid. Online bath purification with the APU® is used in many industries from window manufacturers, steel mills, capacitor plants to copper refineries.
