Sodium Polyaspartate Storage - PASP Biodegradable Antiscalant Tank Selection

Storing Sodium Polyaspartate? Start Here

Sodium polyaspartate (PASP) is a versatile and environmentally friendly chemical, commonly used in water treatment for cooling towers and oilfields, as well as in agriculture. It's biodegradable and non-toxic, making it a safe choice for many applications. Whether you're a water-treatment operator or a farmer, understanding how to store this chemical properly is crucial for maintaining its effectiveness and ensuring safety.

Can you store it in a poly tank?

Yes, you can store sodium polyaspartate in a polyethylene tank. The chemical's mild alkalinity is well within the compatibility range of HDPE and XLPE tanks, making them ideal for storage. Polypropylene fittings and EPDM gaskets are also standard and suitable for use with PASP.

Key Issue: Material Compatibility

While PASP is generally non-aggressive, it's important to ensure that the materials used in your storage system are compatible. HDPE tanks with polypropylene fittings and EPDM gaskets are standard. Avoid using galvanized steel for concentrated solutions, as it can slowly attack zinc. Always match gaskets and seals to the manufacturer's compatibility chart to ensure longevity and safety.

The safety that actually matters

• Ensure tanks are made of compatible materials like HDPE or XLPE.
• Use polypropylene fittings and EPDM gaskets for optimal performance.
• Avoid galvanized steel for concentrated solutions to prevent corrosion.

Common questions

Is sodium polyaspartate safe for the environment?

Yes, PASP is biodegradable and non-toxic, making it a safe choice for environmental applications.

Can I use existing tanks for PASP storage?

If your tanks are made of compatible materials like HDPE or stainless steel, they can be used for PASP storage.

What should I do if I have galvanized steel tanks?

For concentrated solutions, it's best to avoid galvanized steel due to potential zinc corrosion. Consider using alternative materials.
