Storage Containers for Peracetic Acid

Peracetic acid (PAA), or peroxy-acetic acid, is a powerful oxidizing biocide that has gained popularity across various industries due to its effectiveness and versatility. Whether used in food safety, municipal wastewater treatment, or hard surface sanitation, PAA’s ability to destroy microorganisms on contact makes it a top choice for companies requiring stringent sanitation standards. However, storing PAA safely and efficiently is a crucial aspect of its application. This blog delves into the best storage solutions for PAA, ensuring safety, longevity, and efficiency.

What Is PAA?

PAA is a highly oxidizing organic acid that functions as a “super green” bleach, free of chlorine. Unlike sodium hypochlorite (household bleach), which inhibits bacterial or mold growth, PAA completely destroys microorganisms by donating oxygen to their cell walls, preventing resistance buildup. Its superior oxidizing properties make it highly effective but also demand careful handling and storage.

Why Proper Storage Matters

As a potent oxidizer, PAA reacts with many materials, leading to degradation or potential safety hazards. Improper storage can reduce its shelf life, typically up to a year under ideal conditions, or compromise safety. With concentrations ranging from 300 ppm to 30%, finding the right container ensures that the chemical remains effective and stable.

Key Features of Ideal PAA Storage Containers

Given PAA’s highly reactive nature, storage containers must meet specific criteria:

1. Material Compatibility
   PAA is corrosive to many materials. Therefore, it’s essential to use tanks specifically engineered for high-resistance performance. Cross-linked polyethylene (XLPE) tanks are ideal because of their durability and resistance to the oxidizing properties of PAA.
2. Enhanced Antioxidant Systems
   The OR-1000™ antioxidant system, used in cross-linked polyethylene tanks, provides four times the antioxidant strength of standard polyethylene, offering unmatched protection against the oxidative effects of PAA. This system has been a trusted solution for storing PAA since the 1990s.
3. Capacity and Concentration Management
   For applications requiring large volumes of PAA, higher concentrations can be more economical. Containers must be capable of safely handling the volume and concentration levels specific to the intended use.
4. Temperature Stability
   PAA storage containers must ensure stability over time, preventing degradation due to environmental temperature fluctuations.

Benefits of Using XLPE Tanks with OR-1000™

• Chemical Resistance: Designed to withstand PAA’s oxidizing properties, ensuring minimal degradation.
• Cost-Effectiveness: Reduces the need for frequent tank replacements, lowering long-term costs.
• Enhanced Safety: Minimizes the risks associated with leaks or chemical reactivity.
• Proven Performance: Industry-trusted solution for over three decades.

Conclusion

When it comes to storing peracetic acid, safety and longevity are paramount. Choosing the right storage container, such as cross-linked polyethylene tanks with the OR-1000™ antioxidant system, ensures that PAA remains effective while mitigating risks. Proper storage protects your investment and maintains the integrity of your sanitation processes.
