Household water treatment and storage programs are subject to compromise from three primary sources:

  1. Water source quality,
  2. Transportation and storage recontamination, and
  3. Away-from-home consumption

While considerable time and resources have been spent on water source quality issues, relatively few have been expended on solving the problem of recontamination and away-from-home consumption. A variety of global organizations, including UN agencies such as WHO, have acknowledged the importance of solving these problems. Addressing this problem, a recently published article in EHP (Environmental Health Perspectives, Volume 116, Number 11, November 2008) has determined that as much as 50% of clean source water is recontaminated prior to consumption. Additionally, in-home treatment generally neglects drinking water disinfection for water either sourced or consumed at work, in the marketplace, or in the farmer’s field. Clearly, a comprehensive solution to household water treatment and storage issues faced in developing countries today must effectively deal with water source quality, recontamination and away-from-home consumption.

Conventional Wisdom

The prevailing theory over the last 50+ years is that chlorine-based compounds are universally safe and effective, and any side effects are “acceptable risks” relative to the effects of water-borne pathogens. Today, that wisdom is only partly correct. Chlorine-based disinfection agents react with the pathogens they kill and create carcinogenic by-products called trihalomethanes, including chloroform. A growing body of medical professionals and institutions has determined that chlorine disinfection by-products are a leading cause of bladder/stomach/colon/rectal cancers and have been linked to arteriosclerosis. Studies published in The Journal of the National Cancer Institute and The Environmental Defense Fund are consistent with statements made in a 2003 WHO report. It may be presumptuous to consider these “acceptable risks” any longer acceptable in the face of emerging technology.

Emerging Technology – Introducing SilverDYN®

SilverDYN® has demonstrated superior disinfection power, without the risks inherent in chlorine-based solutions. By most definitions, SilverDYN® is an organic compound, effective in treating drinking water after just 30 minutes at concentrations as low as 90 parts per trillion.

SilverDYN® is a clustered, double-distilled water compound, consisting of a colloidal silver-based stable suspension that forms a non-toxic, non-chemical, and non-hazardous product. When used as directed, SilverDYN® will disinfect water without any taste, odor, color, or toxic effects. SilverDYN® is engineered and manufactured using proprietary engineering that utilizes special clustering de-ionized water and other processes that keep silver particles in suspension for increased absorption and efficiency. The result is a true colloidal silver suspension that is lethal to bacteria and other biological contaminants but harmless to humans and the environment.

SilverDYN® has been rigorously tested in third party laboratories around the world and been demonstrated effective thereby. Additionally, SilverDYN® has been used extensively in a wide range of ambient environments in steady state and emergency conditions.

SilverDYN® Benefits

SilverDYN® is the natural successor to chlorine-based water disinfection, having been rigorously tested by third party laboratories around the world to eliminate 99.999% of water-borne bacteria such as E. coli, Salmonella, and Cholera. SilverDYN® eliminates a very broad spectrum of pathogens, algae, and fungi.

Other important benefits include:

  • Depending on the quality of the water being treated, a 30-ml bottle can disinfect up to 1,200 liters, which can be about one year’s worth of drinking water.
  • It is very simple to use – both children and adults can make their own safe drinking water.
  • It is very portable. SilverDYN® is an ideal solution for away-from-home use, even where water sources may be worse than home/city/municipal offerings.
  • There is no residual taste and odor.
  • It is non-chemical, non-corrosive, and non-oxidant – it will not harm the environment (plants, soil, animals, people).
  • Silver is not consumed by or bonded to the pathogens it kills; rather, it keeps killing until pathogens are gone.
  • SilverDYN® prevents pathogens from forming inside storage containers, thereby eliminating re-contamination of safe water during transport.
  • The shelf life of SilverDYN® is the life of the package. SilverDYN® does not degrade or expire.
  • SilverDYN® can be used to coat ceramic tableware and filters, increasing effectiveness.
  • It can also be used in a baby’s bath, eliminating bacteria linked to illness.
  • It can kill bacteria on most fruits and vegetables, extending their shelf life.
  • It can kill bacteria on cuts, blisters, and open sores, promoting faster healing.

Various and Differentiated Uses of SilverDYN® Point-of-Use Drops

The health benefits from SilverDYN® in drinking water are just the beginning of the list of benefits of having this product in the homes and pockets of people in the developing world. SilverDYN® can also be used for:

  • For disinfection of fruits and vegetables via post harvest soaking, improving food safety and extending shelf life;
  • For disinfection of cuts, wounds and scrapes on the surface of the skin, preventing blood borne infections
  • As a treatment of the symptoms of a wide variety of fungi and bacteria affecting the skin of humans and animals; and
  • As a dental rinse for those at risk of bacterial infections due to dental issues.

Comparison to the Use of Chlorine-Based Products

Chlorine tablets and other chlorine-based products have long been used to clean water; however, there are growing concerns about its use to disinfect water for drinking.

  • Chlorine is a powerful oxidizer. In the body, chlorine destroys cells and proteins, and can form hydrochloric acid which is very corrosive to internal organs.
  • Harmful effects occur if inhaled, ingested, or if it comes in contact with eyes and skin.
  • Chlorine in gaseous form is much heavier than air, and accumulates near ground level, affecting children and livestock before adults.
  • There is no antidote to chlorine poisoning; the treatment is flushing skin, eyes, lungs, body, or intestines with clean water (which the user doesn’t have).
  • Chlorine bleach is made by hitting salt water with an electrical charge, then adding oxygen. It can be made locally anywhere you can find salt or salt water. It is diluted in order to make it safer for handling and distribution, making it expensive to ship, and leading to a high number of local manufacturing plants.
  • Bleach-based water purification chemicals are concentrated to reduce package expense and freight costs. In many places in Africa, you will see people with bleached feet. When surface water is hard to find, people will dump the concentrated chlorine into puddles. Each chlorine packet or bottle will purify from 12 to 20 liters based on the amount of chlorine. If the puddle is 3 liters and the user puts in chlorine for 20 liters, you have created a health and safety risk. People will breathe and ingest the over dosed water and can be poisoned.
  • If people walk through that water, it will bleach the color out of their skin. The puddle also creates an area where you can no longer grow crops; it is lifeless.
  • Bleach has been the only product available for point-of-use purification for the last 60 years, and it is used responsibly by many people throughout the world. Despite its recognized risks, some world organizations have decided that bleach is an “acceptable risk” for African children as it is safer than untreated water.
The significance of SilverDYN® is that the people can get clean water at essentially the same price per liter, without any of the risk inherent in the use and storage of bleach.


SilverDYN® is the obvious next generation solution for the household water disinfection and storage challenges of the new millennium. SilverDYN® is effective, simple to use, environmentally friendly, suitable for sustained operations as well as disaster relief, and is available in large quantities immediately.
