Sulfuric acid purification for aluminum anodizing
In aluminum anodizing, maintaining low levels of dissolved aluminum in sulfuric acid baths is critical to ensuring consistent and high-quality finishes. Without effective purification, contamination can escalate, leading to frequent decanting, increased acid purchases, and unpredictable anodizing results.
Continuous sulfuric acid purification
The AnoPur™ system by Kovalus Separation is a specialized sulfuric acid purification solution for aluminum anodizing processes. This system continuously removes dissolved aluminum from sulfuric acid used in anodizing baths. By reducing contaminants to consistently low levels, it eliminates the need for frequent bath decanting and reduces overall acid purchasing costs. This technology is based on the previously developed APU® system and delivers predictable and stable anodizing quality. With its focus on maintaining a clean anodizing bath, AnoPur™ ensures the longevity and efficiency of the anodizing process.
Benefits
- Reduced acid purchasing costs
