Huwa-San is a unique formula of hydrogen peroxide which has been stabilized and catalyzed by the addition of a small quantity of silver.
How does Huwa-San work?
While neither hydrogen peroxide nor silver are particularly very good water system disinfectants when used individually, the combination produces a superb biocide. The mechanism is thought to be as follows: Hydrogen peroxide is not very effective against bacteria because these micro organisms can secrete Catalyze which reacts with hydrogen peroxide preventing it from reaching the cell wall and destroy the bacterium. Therefore, if hydrogen peroxide is used alone a huge quantity is required. This is where the silver plays an important role. The silver emits electrostatic which de-stabilize the bacteria defense system (catalyze enzyme) and allow the hydrogen peroxide to attack and destroy the bacteria. When the bacterium is dead, it is no longer attracted by the silver which moves back into the bulk water pulling the hydrogen peroxide behind it. This makes the solution very stable in water. The product also effervesces on the pipe wall helping to remove biofilm. Essentially the product has the chemical and physical properties required to remove and treat biofilm
How stable is the product?
Huwa-San will remain active in cold water for many days and possibly weeks, depending on dosage level, environmental conditions and water quality, and if there are no bacteria for it to kill or other organic material for it to react with. It is also stable up to 113ºC and therefore does not break down in domestic hot water systems (generally operating at around 60ºC).
What proof is there that Huwa-San is good at eradicating legionella from domestic water systems?
An efficient legionella bactericide needs to do three things: 1. It must be a fast legionella,Listeria and Gardia bactericide; 2. It must destroy the protozoa which can act as host for the legionella bacterium; 3. It must be capable of removing biofilm which can protect the legionella micro organism. A wide range of independent tests have confirmed that Huwa-San does all these things when added to a water system.
Why do we need to disinfect?
Disinfection is different from cleaning.
Cleaning = the activity of making things clean, in a domestic or commercial environment.
Disinfection = the process that effectively kills or eliminates disease carrying microorganisms and prevent infection.
There are a lot of hydrogen peroxide products in the market, why Huwa-San?
Huwa-San is a unique formula and has gotten approvals from different organizations & governmental agencies worldwide in the past 25 years.
Huwa-San provides 99,9% disinfecting ability as documented by scientific researches and laboratory tests worldwide.
The "Know how" of the manufacturing process is difficult to copy or imitate which gives the product the power to attack effectively all types of germs without any physical or chemical hazard.
Does Huwa-San clean?
We recommend Husa-San for disinfection use after normal cleaning.
Is Huwa-San safe for food?
Huwa-San is safe for disinfection of fruits, vegetables, meat and fish by rinsing or washing at suggested dosage.
Are there any storage temperature constraints for Huwa-San? Can it be stored outdoors?
Since Huwa-San is formulated to be very stable, it can be stored outdoor in high temperatures.
However we recoomend storage indoor.
Method of checking the quality of Hwua-San
Huwa-San cen be checked with peroxide strip of using spectrograph test method.
Is Huwa-San corrosive?
Huwa-San is not corrosive at the recommended doses for most surfaces like stainless steel, aluminium, plastics etc. Not recommended for bras and copper.
Does Huwa-San bleach?
Not at the recommended doses below 1%.
Does Huwa-San damage skin tissue?
Not at recommended doses. Huwa-San is skin safe below 3%.
What about the silver residue?
The silver content in Huwa-San is at ppb levels in all applications, far less than international recommendations.
What method of analysis is used to check the residual level of Huwa-San in drinking water?
There are many methods:
Spectograph manual test
Spectgraph automated test
Can Huwa-San be mixed with other disinfection products?
Not recommended to be mixed.
Does Huwa-San needs rinsing after application?
No, Huwa-San consists of non toxic components which are biodegradable to 2 essential natural elements, water and oxyen.
What is Huwa-San's shelf life?
Under ambient conditions Hwua-San has a shelf life of 2 years.
