AnoPur™ is a version of Eco-Tec’s Acid Purification Systems specifically adapted for purification of sulphuric acid used in aluminum anodizing.
Hundreds of AnoPur units are in operation in anodizing facilities around the world.
The Anopur is used to continuously remove dissolved aluminum from sulfuric acid anodizing baths in order to maintain the dissolved aluminum at a consistently low concentration.
Consistent, predictable anodic film characteristics (thickness, density) to assure consistent appearance. This is especially critical in maintaining consistent color in subsequent electrolytic color or organic dyeing steps.
Consistent, predictable current and voltage requirements. This allows for full automation of the anodizing process.
Lower electrical current and cooling requirements due to the higher conductivity of purified anodizing solutions
Eliminates downtime for dumping and reformulating anodizing baths.
Reduces acid purchases and waste treatment costs
