Sodium Gluconate Storage — Concrete Admixture + Biodegradable Chelant Tank

Storing Sodium Gluconate? Start Here

Sodium gluconate is a versatile chemical often used in concrete admixtures and as a biodegradable chelant. It's a white crystalline solid that dissolves well in water, making it easy to handle in both dry and liquid forms. It's environmentally friendly, breaking down easily in wastewater treatment, unlike some other chelants. If you're dealing with sodium gluconate, you might be using it in construction, cleaning, or even food applications.

Can you store it in a poly tank?

Yes, sodium gluconate is compatible with polyethylene tanks. It has a neutral pH and is non-oxidizing, making it safe for use with a wide range of materials including HDPE, XLPE, and other polyolefins. Just ensure your tank is suitable for the temperature range you need.

Watch out for crystallization in cold weather

If you're storing sodium gluconate solutions, be cautious in colder climates. Solutions over 40% may start to crystallize below 30°F. Consider heat tracing your storage tanks to prevent this from happening.

The safety that actually matters

• Ensure tanks are compatible with the chemical to prevent leaks or degradation.
• Monitor temperatures to avoid crystallization in cold environments.
• Use appropriate gaskets; match them to the manufacturer's compatibility chart.

Common questions

Is sodium gluconate environmentally friendly?

Yes, it biodegrades well in wastewater treatment, unlike some other chelants.

Can I use sodium gluconate in food applications?

Yes, it's recognized as safe for use in food by regulatory bodies like the FDA.

What should I do if my solution starts to crystallize?

Consider adding heat tracing to your storage tanks to maintain a stable temperature.
