Ensuring BPR PT5 compliance for silver peroxide in water treatment

Navigating the realm of water treatment products can feel like walking through a maze, so it's crucial to choose wisely. One standout option gaining attention is the Huwa-San range, distributed by B&V Chemicals in the UK and produced by Roam Technology Ltd. But for water treatment experts, the burning question is whether their current silver peroxide product meets PT5 standards of the Biocidal Product Regulation (BPR).

Understanding Biocidal Products Regulation (BPR) and GB BPR Compliance

The BPR, or Biocidal Products Regulation, oversees the market placement and use of products designed to shield against harmful organisms. With Great Britain now detached from the EU's biocide regulations post-Brexit, the GB Biocidal Products Regulation (GB BPR) mirrors its EU counterpart, aligning standards. Roam Technology Ltd has diligently ensured compliance with GB BPR for its Huwa-San products, underscoring its commitment to quality and regulatory alignment.

One standout example of compliance is Huwa-San TR50, also known as SuPerSil in B&V Chemicals' lineup, which has secured approval under specific product types outlined in the BPR. This endorsement solidifies its reputation as a dependable silver-stabilized hydrogen peroxide for water treatment.

What silver peroxide users need to know

It's crucial for water treatment outfits to confirm the compliance of their silver peroxide products under PT5 of the BPR, especially when it comes to applications involving drinking water. Not all products hold this vital approval, and using non-compliant ones could jeopardize public health and regulatory adherence.

Enterprises relying on Huwa-San TR50 can rest assured in the compliance of their silver peroxide solution, thanks to the efforts of Roam Technology Ltd and B & V Chemicals.
