Huwa-San is a solution of Hydrogen Peroxide (H2O2) which is stabilised using a proprietary ionic silver based chemistry.

When correctly applied to water, air or any surface, Huwa-San will disinfect through an oxidisation process and continue to safely provide excellent residual performance.

Huwa-San is chlorine and alcohol-free, with no corrosive effects on usual materials of construction during application. After use, it simply degrades into harmless water and oxygen.

Product Benefits

• Broad spectrum high-performance biocide effective against all kinds of bacteria, viruses, yeast, mould and spore formers
• Efficacy against Legionella pneumophila
• Environmentally friendly – practically 100% degradable breaking down to water and oxygen … (2 H₂O₂ = 2 H₂O + O₂)
• Does not create odour or alter the taste of foodstuffs treated
• Effectiveness and long-term effects are seen even at very high water temperatures
• Assessed as safe for consumption at the recommended dose rate
• No carcinogenic or mutagenic effect
• Does not react with ammonium-ions – no ‘breakpoint’
• By adding oxygen, anaerobic conditions in the cooling water are largely avoided, thus preventing the growth of sulphate-reducing bacteria (formation of corrosive hydrogen sulphide – 4 H₂ + SO₄^2- S^2- + 4 H₂O)
• Long-term effectiveness: reliably prevents recontamination
• Toxicology: harmless, neither carcinogenic nor mutagenic
• Storability: very long, max. loss of concentration 3% per year
• Corrosion: very low corrosive effect at recommended dose rate
• Measurement and regulation – complete installation programme available
• Expenditure for equipment resp. investment costs: negligible
• Operating costs: low

Uses

• Irrigation water disinfectant
• Removal of biofilm in water systems (Sprinkler systems, drip irrigation, circulation water)
• Disinfection of surfaces, floors, walls, and equipment in agriculture (greenhouses, hydroculture, hydroponics etc.)
• Substrate disinfection
• Surface disinfection of entire greenhouses by product vapourisation (“fogging”)

Intended users

Greenhouses, hydroculture, horticulture, floriculture, juvenile producers, seed growers etc.
