Disinfection with H2O2 Ag+ against all kinds of bacteria and germs
Evaluation of Alternative Legionella Disinfection Technologies
The Acceptability of the Disinfectant Formulation for Treatment of Drinking Water
The active ingredients of the commercial disinfectant formulation under study are non-toxic H2O2 and silver. H2O2 has been approved for drinking water disinfection at the concentration required for this anti-Legionella treatment in Europe under “European Standard- EN 902–1999 - Chemicals used for treatment of water intended for human consumption-hydrogen peroxide”.
The use of silver at the concentration required for drinking water disinfection has been approved by the WHO, the EU and the United States Environmental Protection Agency. The commercial formulation has been specifically approved for drinking water disinfection by the USEPA under FIFRA, by the Drinking Water Inspectorate (DWI) in the United Kingdom and the by health authorities in Australia.
Hydrogen Peroxide (H2O2)
H2O2 looks like water (H2O), but that extra oxygen molecule makes this natural water additive one of the most powerful oxidizers known to man. It is formed in nature by the action of sunlight on water, and even in honey!
Hydrogen Peroxide is a strong oxidizer used for high-level disinfection and sterilization.
"...consider an estimate from the CDC that close to one million Americans annually become ill and about 1,000 die because of a variety of microbes carried in the nation's water supply"
"Some 4,000 children die daily from illnesses caused by unclean water
The UN says the world faces a silent emergency because of the continued lack of clean water and sanitation."
Chlorine - A Special Problem
Chlorine as stated above is a very effective disinfectant and has been used in drinking water supplies for nearly 100 years. What concerns health officials are the chlorination by-products, "chlorinated hydrocarbons,"known as trihalomethanes (THM's). Most THM's are formed in drinking water when chlorine reacts with naturally occurring substances such as decomposing plant and animal materials. Risks for certain types of cancer are now being correlated to the use of chlorinated drinking water. Suspected carcinogens make the human body more vulnerable through repeated ingestion and research indicates the incidents of cancer are 44% higher among those using chlorinated water.
Disinfection of drinking water and sewage uses small amounts of chlorine which have major health and environmental impacts.
Organic matter in the water combines with the chlorine to form many hundreds of organochlorine byproducts. Among the best understood are the trihalomethanes, which includes chloroform. The trihalomethanes are known carcinogens, and chlorination of drinking water is increasingly being linked to a range of human cancers and other serious health problems such as increased susceptibility to cardiovascular disease.
Since its introduction as a water disinfectant in 1908, there have been countless lives spared from waterborne diseases including cholera and typhoid. The use of chlorine in drinking water has saved probably more lives than penicillin and antibiotics combined (Shuval et al 1995).
1974, Johannes Rook discovered that chlorine formed toxic Disinfection By-Products (DBPs) with organic matter in drinking water leading to rectal and bladder cancer (Rook 1974).
"There is increased evidence for an association between rectal, colon and bladder cancer and the consumption of chlorinated drinking water", this according to the President's Council on Environmental Quality.
[Health Note: CHLORINE added to your drinking water is very BAD]
Recent epidemiological evidence has linked DBPs with other adverse health effects including reproductive development.
DBPs are as well linked to other disinfectants such as chlorine dioxide, chloramines, bromine and ozone (Batterman)
There is now enough evidence to support calls by Greenpeace for an end to chlorine chemistry. Significant advances have been made internationally to begin the phase-out of chlorinated chemicals, most recently the Washington Declaration of November 1995, which called for the urgent development of a legally binding instrument to phase out persistent organic pollutants (POPs).”
“The ultimate goal is an end to toxic pollution of our food, water and environment, and to assist in building a clean future for our children and all future generations.”
Requirements On Todays Disinfectants
• Disinfectant should be able to control the kinds and numbers of organisms present within a reasonable contact time.
• It should be available at reasonable costs and safely applicable.
• In the concentrations employed, it should accomplish the desired objectives without rendering the water toxic.
Facts about H202 in combination with Silver
- According to the EEC, WHO, and the USEPA silver and hydrogen peroxide pose no harmful effects to humans (Pedahzur et al 1995).
- The USEPA has not set any drinking water MCL (Maximum contaminant Level) standards for hydrogen peroxide (USEPA 2001).
- France, Germany, Switzerland and Australia have all approved Hydrogen Peroxide/Silver products for drinking water disinfection (Pedahzur et al 1995, Shuval et al 1995
- The combination of silver with hydrogen peroxide forms a powerful virucidal and bacteriostatic agent. (Shuval et al 1995, Batterman et al 2000, Pedahzur et al 2000)
- Research revealed that the Hydrogen Peroxide/Silver system is a safe and effective bacteriostat and virucidal agent with a long residual effect that does not offer any disagreeable appearance, odor or taste (Shuval et al 1995, Pedahzur et al 2000 and Liberti et al 2000).
- Most importantly the system did not produce any DBPs or other toxic substances. Decomposition to oxygen and water.
- The European Union does not dictate any standards considering silver concentrations in the water (EU Drinking water directive 98/83/EC, 1998).
- The WHO does not dictate any standards considering the concentration of silver as a drinking water disinfectant (WHO, Guidelines drinking water quality, 3rd edition).
- The United States dictate a maximum value of, 0,1 mg/L of silver. (EPA, National Secondary Drinking Water regulations, 2002).
Conclusion: Oxytech D50/500
• is ecologically friendly: Its basic ingredient Hydrogen Peroxide disintegrates into natural form of water and oxygen, without the formation of any by-products.
• can be applied for numerous applications. It can be used in all media - air, water, hard surfaces, waste water, soils etc.
• combats a wide range of pathogens and micro-organism, making it an ideal choice for various disinfection needs.
• remains stable at elevated water or air temperatures for a long time.
