DBNPA Biocide Storage — 2,2-Dibromo-3-Nitrilopropionamide Tank Selection

Storing DBNPA Biocide? Start Here

DBNPA is a fast-acting biocide commonly used in industries like cooling towers, paper mills, oilfields, and metalworking. It quickly kills microbes and then breaks down in the environment, making it ideal where lingering residues are a concern. It comes in two forms: a liquid concentrate and a dry granular form for mixing before use. If you're looking to store DBNPA, understanding the right materials and conditions is crucial for safety and effectiveness.

Can you store it in a poly tank?

Yes, you can store DBNPA in a polyethylene tank, but only if it's the diluted feed solution. The liquid concentrate, which contains dimethylformamide (DMF), requires careful material selection due to its aggressive nature. HDPE tanks with polypropylene fittings and Viton or PTFE seals are recommended for concentrate storage.

Key Issue: Material Compatibility

The DMF carrier in DBNPA's liquid concentrate can dissolve or damage certain materials. Avoid using PVC and EPDM, as DMF will compromise them. Always ensure that your tank and fittings are compatible with DMF to prevent leaks or damage.

The safety that actually matters

• Use HDPE tanks for storing DBNPA concentrate.
• Ensure fittings and seals are made from compatible materials like polypropylene and Viton.
• Avoid using PVC and EPDM with DBNPA concentrate.
• Handle with care to prevent exposure to the aggressive DMF solvent.

Common questions

Can I store DBNPA in any plastic tank?

No, only specific plastics like HDPE are suitable for the concentrate. Always check compatibility.

What seals should I use with DBNPA?

Viton or PTFE seals are recommended for the concentrate due to their resistance to DMF.

Is DBNPA safe for the environment?

Yes, DBNPA breaks down quickly, reducing environmental impact after use.
