A company history
The history of Katadyn goes back to an invention of Professor Alexander Krause from Munich to use electrolysis to deposit silver ions in water in order to clean it bacteriologically.
Last century, Katadyn started production of ceramic filters in the 1930s and moved its headquarters to Switzerland. In 1954, the company moved to a building in Wallisellen.
In the 1970s, Katadyn expanded its operations to include municipal water treatment with UV irradiation.
At the end of the 1980s, production was concentrated and expanded with a new building at the Wallisellen site. This new building led to considerable financial burdens, which made refinancing necessary in the mid 1990s.
At the beginning of 1997, Adrian Schmassmann took over operational management and launched an extensive restructuring program, which led to the company being profitable once again as of 1998.
At the end of 1998, Adrian Schmassmann together with other members of management acquired the Katadyn Group as part of a management buyout.
In 1999, activities in the UV water treatment sector were merged with the German competitor WEDECO, and the company went public.
In 2001, Katadyn was able to take over the two American companies Exstream and PUR Outdoor, which made it the largest supplier of portable water treatment systems. Portable seawater desalination systems were added through PUR Outdoor.
The French subsidiary was established in 2002 by buying a reseller, and a sales office was opened in Singapore.
The takeover of Trekking-Mahlzeiten GmbH in Germany followed in 2004 and entry into the field of freeze-dried outdoor nourishment. Increased vertical integration was also initiated through the company's own production of plastic components.
History since 1899

General Information about Water
Standing or flowing bodies of water are referred to as surface water. It is normally a mixture of groundwater and spring and rain water, although it may also contain waste water. Streams, rivers and lakes may contain minerals in widely varying proportions. Because of the numerous organisms living in and around bodies of water, many organic substances, mostly metabolic, can be found in the water. Frequently, surface water is contaminated by heavy metals and organic compounds introduced from industrial plants and households. A very problematic source of contamination is also agriculture, namely farming that is not ecologically friendly. In addition to pesticides and herbicides, whose active ingredients often contain halogenated hydrocarbons, large amounts of phosphate and nitrate (fertilizers) and organic substances (manure) may enter water from these sources. All surface water contains various bacteria, viruses and protozoans.
The World Health Organization (WHO) attributes 80% of all travel diseases to contaminated drinking water. Don't let contaminated drinking water spoil your trip. Avoid tap water and ice cubes anytime the water quality is uncertain even bottled water can be questionable, when available. According to WHO, almost half of all travellers suffer from some form of diarrhea while en-route.
Good health while travelling starts with travel preparation – and the right Katadyn product for safe drinking water.
Drinking water contains three groups of pathogenic microorganisms:
|Family||Known germs||Size range|
||Hepatitis A, Norwalk Virus, Rotavirus, Poliovirus||~0.02 - 0.2 microns|
||E-coli (Escherichia coli), Salmonella (Salmonella typhimurium), Cholera (Vibrio cholerae)||0.2 - 5 microns|
||Amoeobiasis (Entamoeba histolytica), Giardia lamblia (Giardia intestinalis), Cryptosporidium (Cryptosporidumparvum)||1 - 15 microns|

A large number of additional pathogens are known besides the germs listed above. But according to WHO, their pathogenic (disease-inducing) action is only slight, or they are primarily absorbed along with food.
Why Treat Water?
Because you never know what's in the water, it makes sense to always protect yourself with a quality water system. A pristine stream may be safe one day and contaminated the next. It all depends upon what's happening upstream. Microorganisms generally come from human and animal waste and are spread by rain and run-off. The EPA reports that 90% of the world's fresh water supply is contaminated.
"We highly recommend treating water from every source in the backcountry. You don't know what's upstream - not just people but animals - and you can get infected."

Hygiene tips for traveling
Fruit that you peel to eat is safe, for example citrus fruit, bananas, pineapples, papayas and mangos.
When travelling to many countries, special precautions should be taken to avoid sickness from microorganisms in food and especially water. Many countries still fertilize with human excrement, making it important to follow a few tips to avoid getting sick.
- Order your drinks without ice, if you are unsure that the ice is germ-free.
- Drink only industrially bottled beverages. "Open" or unsealed bottles could be filled from a contaminated source.
- Order your food well-cooked. Avoid raw or slightly cooked food, seafood, mayonnaise, ice cream, butter, etc.
- Avoid eating food from street vendors.
- Only eat fruits, raw vegetables, or salads if they were washed with germ-free water. Otherwise, you can wash them yourself with disinfected water.
- Avoid raw milk. Pasteurized milk is safe to drink.
- Fruit juices with high sugar content are an ideal medium for bacteria to grow. Only drink fruit juices if the fruit, blender, and anyone's hands in contact were hygienically cleaned.
- Fresh hot coffee and tea are safe beverages. Beer and wine are also typically safe. Note: Alcoholic beverages do not disinfect bacteria already in the stomach.
- Brush your teeth with germ-free water. Even a small sip of contaminated water can cause diarrhea.
- Always use germ-free water when taking medicines. Diarrhea is not only uncomfortable; it could also affect the impact of the medicine (i. e. tablets).
- Don't bathe in tropical surface water.
- Wash your hands regularly, especially after using the toilet and before contact with food.
- Always use clean towels.
