B & V Chemicals are the UK distributors for the Huwa-San range of silver stabilised hydrogen peroxide products produced by Roam Technology -

Huwa-San TR-50 is the most advanced, proven, and highly developed silver stabilised hydrogen peroxide available anywhere on the global market and is widely regarded as a true, credible alternative to chlorination.

Huwa-San contains one active substance, Hydrogen Peroxide (H₂O₂). stabilised with very small amounts of ionic silver using a proprietary stabilisation technique, which is unique to Huwa-San. This ionic silver stabilisation system allows hydrogen peroxide to remain residual for longer in a water system.

Huwa-San has extensive BPR – Biocidal Product Authorisation. The dossier was formally accepted by the EU competent authorities for the EU BPR and the HSE for the GB BPR. Under market freeze conditions set down by both the EU CA’s and HSE Huwa-San is legally compliant and is permitted to be sold in the UK for application classes PT02, 03, 04, 05. Huwa-San TR50 is also listed as an approved constant dose biocide in the HSE ACOP HSG274 Pt2:
