• Silver was used in early historic days but
too slow acting on bacteria
• Hydrogen Peroxide was developed in 1800
but too fast and no stability

The rest (49.9960%) is demineralised water
2-5 year shelf life (1.2% per year loss on storage)
Stable up to 95-113 oC
Breaks down to water and oxygen
Two poor disinfectants become a Great Disinfectant
20-1000 times more effective than H2O2 alone
H2O2 & Colloidal Silver Background


H2O2 is formed by our immune system and naturally in the environment
H2O2 is used widely used in the food industry. It is the only chemical
approved to use directly on foods by the FDA.
However, H2O2 is not stable in storage and reacts very fast in
water/food
H2O2 does not provide any residual in water for post water disinfection
H2O2 is EPA approved as a water disinfectant
LD 50 > 2000 mg/kg (Toxicity L Dose) European Commission CAS
No 7722-84-1
Colloidal/Ionic Silver is used from the early historic days until today as a
water disinfectant. Also used in the medical/pharmaceutical as an
antibiotic to kill germs- Best Germ Fighter.
Silver is non-toxic to human. Colloid of silver was the only form of
silver that was not deposited under the skin.
Silver poses no toxic effects to humans (USEPA 2001, WHO 1993).

Silver Background








Aristotle advised Alexander the Great to store water in silver vessels to
prevent waterborne diseases. Pioneers that crossed America placed silver
coins in their water barrels- Russell (1994).
Before refrigeration, milk used to be stored with coins of silver to
maintain freshness.
Silver was the primary antibiotic used before the advent of pencillin in
1938
Modern ships still use silver for the same purpose- (Laubusch 1971).
In 1950’s silver was used as a bactericide for water purifying systems.
Samsung has recently released a line of washing machines, air
conditioners, air purifiers and refrigerators that use the Silver Nano Health
SystemTM technology (Samsung 2004).
NASA developed silver ionizer to purify drinking water in the Apollo
spacecraft (NASA 2004). Also used by the Russian Airspace for water
purification
Drinking water-purifying systems nowadays contain a silver ionexchange system, a silver tube which acts as a bactericide.
Silver in the Holly Books
Surate El-Insan,
Verse 14 and 20
Silver is also mentioned
in the Bible where
royalty & Phoenicians
carried water in silver
vessels to help them
maintain their health
Psalm
66:10
Isaiah 48:10
Malachi 3:2, 3
Silver Use

Great potency is at 250-500 ppm and particle size should be
less than 0.001 microns. Large particles are less effective, can
remain in tissues and cause bluing of the skin.

Silver retention rate is 0-10% (US-EPA 440/5-80-071)

Studies on Silver Toxicity showed that it is very safe. Higher
level of silver, up to 0.1 mg/liter (a concentration that gives a
total dose over 70 years of half the human NOAEL of 10 g),
could be tolerated without the risk to health (WHO 1996WHO/SDE/WSH/03.04/14).

Silver is EPA approved as a water disinfectant. EU Drinking
Water Standard has removed any upper limit for silver in
drinking water, following the WHO’s Guidelines stating “ It is
unnecessary to recommend any health-based guideline for
silver as it is not hazardous to human health.”

Why Huwa-San is Very Effective?

H2O2 with colloidal silver produces synergy action
 30 ppm of H2O2 alone achieves 90% reduction- 1 log reduction





30 ppb of Ionic Silver achieves 99.0% reduction- 2 log reduction
Combined effect (30 ppm H2O2 & 30 ppb silver) achieves
99.999%- 5 Log Reduction- Synergy Effect*
Silver: Stabilizes H2O2 (Ag++ keeps O--)
Silver: Deactivate enzymes (microbial defense system)
H2O2: Formation of highly reactive free Oxygen &
Hydroxyl Radicals, attack Biological Targets

Huwa-San
How does it work?
1. The Silver Effect
Silver emits
“electrostatic”
The silver weakens the
outer defenses (enzymes) of
the micro-organism
Ag
Hydrogen peroxide stabilised around silver
Huwa-San
How Does it work?
2. The hydrogen peroxide effect
Hydrogen peroxide pull away and
head toward micro-organism
Increase in kinetic energy due to
presence of micro-organism
Ag
Huwa-San the combined effect!
The presence of the Silver
has weakened outer
defense mechanism. This
in combination with the
increased energy of the
hydrogen peroxide leads to:
Micro-organism oxidised
DNA destroyed
Huwa-San The residual
After the reaction with the
micro-organism we are left
with:
O2
H2O
They disappear into the
environment
They loose their kinetic energy…
Ag
… and return to await their next target…

Huwa-San kills cryptosporidium and its Ocysts - Chlorine cannot
Huwa-San breaks down to water and oxygen- Chlorine forms
harmful by-products.
Huwa-San does not have odour and taste – Chlorine does
Huwa-San is safer and easier to use- Chlorine is not
Huwa-San is not affected with pH changes- Chlorine is affected
You can drink water containing disinfection levels of 200 ppm
Huwa-San level - Chlorine you cannot
Huwa-San is stable at high temperature and even becomes more
effective - chlorine is not - evaporates at 35 C and is less
effective with higher temperatures

Cost is the Buzz Word

Cost efficiency of the chemical

Efficiency/volume used (swimming pool, results show ½ volume is
needed for Huwa-san vs chlorine, to reach 2 ppm dose 10x more)
Benefits of each chemical (biofilm/legionella/ pseudemonas, byproducts, odor/taste, etc….)
It is not cost/kg alone:
 Risk assessment
It is Quality, Value,
Water born outbreak risks are reduced- Public Health

Benefits





Breaks down THMs and many other byproducts
Economic Impact



Cost savings (i.e. better quality, better yield/weight, more business,
etc). For poultry you may pay 1 fils extra but you get much more
benefits (23 g extra/chicken, less cost on antibiotic, less mortality)
No rinse is needed, etc…..
Trade with other countries
Summary







Is the best chemical available for disinfection in the water
food industry (no odor, no taste, and no post rinse)
Combine advantages not obtainable within any other
single form of chemical
Effective: Very powerful against all microbes (Spores,
virus, fungi and bacteria i.e. E. coli and Legionella)
Stable: Provides residual in water for post contamination
Efficient: Depo storage- activate as needed- Cost effective
Easy to handle and store
Eco-friendly: Non toxic byproducts- O2 prevent
anaerobic bacteria/sulfide production, destroys chlorine
carcinogenic byproducts
