Sodium Sulfate Storage — Na2SO4 Glauber's Salt + Kraft Mill Tank

Storing Sodium Sulfate? Start Here

Sodium sulfate is a widely used industrial chemical, appearing as a white crystalline solid. It's commonly used in detergents, glass production, and textile processing. When you're considering storage options, it's important to know that sodium sulfate is generally non-hazardous and has a neutral pH, making it quite safe to handle. However, if you're dealing with concentrated solutions, you might need to take extra care to prevent crystallization at low temperatures.

Can you store it in a poly tank?

Yes, you can store sodium sulfate in a poly tank. Polyethylene and other polyolefins are fully compatible with sodium sulfate, whether in solution or as a dry crystal. This makes poly tanks an excellent choice for storing sodium sulfate safely and efficiently.

Watch out for crystallization in the cold

If you're storing sodium sulfate solutions in cold climates, be aware that the solution can crystallize on the tank walls below 32°F. To prevent this, consider using heat tracing to keep your storage system operational without disruptions.

The safety that actually matters

• Ensure tanks are compatible with sodium sulfate to prevent leaks or damage.
• Use heat tracing in cold climates to avoid crystallization.
• Follow manufacturer guidelines for gaskets and seals to ensure compatibility.

Common questions

Is sodium sulfate hazardous to store?

No, sodium sulfate is non-toxic and non-hazardous, making it safe for industrial storage.

What materials are compatible with sodium sulfate?

Most materials, including polyolefins, stainless steel, and concrete, are compatible, though concrete may need special attention in concentrated exposures.

Can sodium sulfate solutions freeze?

Yes, they can crystallize below 32°F, so heat tracing is recommended in cold environments.
