Disinfect your water bubbler with biostream® asepticaPRO.

Danger from drinking water bubbler

How can water bubblers become a hazard? What role do bacteria and germs play there?
Many people appreciate the refreshing „fizzy taste“. However, the water from the tap does not contain any fizzy CO2. The solution: water bubblers enrich tap water with carbon dioxide and thus produce inexpensive, homemade sparkling water.

However, bacteria in water fountains can pose a health risk. With a few simple rules of conduct, however, it is easy to prevent germs and bacteria from contaminating them. Only clean tap water that is free of lead and other harmful substances should be used in water dispensers.


Risks due to bacteria in the water sprayer

Reusable glass and PET bottles are cleaned by the beverage industry in elaborate processes before they are refilled. Refillable bottles are also used for water bubblers. However, they are often cleaned poorly or not at all, or cleaning is made difficult by small bottle necks. This can lead to the growth of harmful germs and bacteria such as E. Coli in and on the bottles or under the lid seals. biostream® asepticaPRO is the right solution for you.

The active ingredient chlorine dioxide, which is also used by waterworks, combats precisely these harmful bacteria that are responsible for germs in the fizzy drinks and fizzy drinks bottles.

In some cases, contamination by germs and bacteria can also cause severe gastrointestinal problems. The risk of contamination of bottles is even greater when drinking directly from them.

If carbonated water is already mixed in the bottles with syrup or fruit juice, for example, the risk of bacteria increases further. Bacteria can also get into water bottles from water filters that are not changed regularly.


The solution: biostream® asepticaPRO fights germs in the water bubbler

Regularly disinfect your bottles and your drinking water bubbler with our product and you will always have hygienically perfect, germ-free sparkling water at hand.



Effective disinfection is that simple:

Pour the activated cleaning or disinfecting solution into a 1-litre PET bottle, fill it with water and then insert it into the appliance. Then bubble up the water until the overpressure (loud hissing) is audibly released three times. Leave the bottle in the unit for at least 60 minutes. Then remove the bottle and rinse it once with drinking water. Ready

Grundlagenwissen Trinkwasser

Wir erklären Ihnen auf nur 6 Seiten, welche Produkte zur Desinfektion von Trinkwasser zugelassen sind und warum silberhaltige Produkte in den USA mittlerweile als Pestizid gekennzeichnet werden müssen.

Basic knowledge:

The active ingredient in asepticaPRO has been successfully used to disinfect drinking water in waterworks since the mid-1950s and has already replaced chlorine – which has the same name but can form harmful disinfection by-products – several times.

biostream® asepticaPRO is an effective biocide with the active ingredient chlorine dioxide, which is extremely effective against viruses and bacteria even at very low concentrations and over a very wide pH range.

Information about an explosive capacity, which can be found e.g. at Wikipedia, does not apply to our product: The concentration of our product is <0.3%. This concentration is definitely not explosive


A study commissioned by biostream® GmbH and conducted by the Institute of Food Science and Ecotrophology at Leibniz University in Hanover under the leadership of Dr. rer. nat. H.-D. Werlein confirms in 1,620 individual tests that the product biostream® ZERO is 99.9% effective against germs occurring in drinking water with exposure times of only 5 minutes.

The biostream® products have been used successfully since 2001 for disinfection in rail vehicles and on ships, in numerous hospitals and clinics, and by well-known beverage manufacturers in practice. Tests at the Institute of Food Science and Ecotrophology at Leibniz University in Hanover under the leadership of Dr. rer. nat. H.-D. Werlein again confirmed the excellent efficacy. Dr. rer. nat. Hans-Dieter Werlein is responsible for the area of food hygiene and microbiology.


Legionella (e.g. Legionella pneumophila) are a water hygiene problem that is often underestimated. They are also the cause of legionnaires' disease (legionellosis).

Legionella settle in the so-called biofilms, which can only be combated poorly or not at all by e.g. disinfectants containing hydrogen peroxide. Chlorine also has less disinfecting power than the active ingredient chlorine dioxide present in our products.

According to the current Drinking Water Ordinance, biostream® products are approved as disinfectants for drinking water. In addition, our products comply with the current requirements of the Biocide Directive.



Our customers combat biofilms, viruses and bacteria in very different application scenarios: The dentist worries about his treatment unit and the yacht owner or camper cares about the perfect hygiene of his water tank. But our products are also used in industry to combat Legionella and E.Coli.

The biostream® products are available in different container sizes and packaging:
We deliver as individually as necessary. For example, biostream® asepticaPRO is available in small 10ml vials that require very little storage space and are therefore ideal for travel and outdoor expeditions.

All biostream® products are approved as disinfectants for drinking water according to the current Drinking Water Ordinance and comply with Article 95 (2) of the Biocide Regulation (Regulation (EU) No. 528/2012).

With the biostream® concentrates based on chlorine dioxide, you now have the possibility to reliably disinfect drinking water tanks, drinking water-carrying pipes and drinking water bubbler bottles. Use the active ingredient of the waterworks without expensive technical expenditure.

The active ingredient in biostream® products (chlorine dioxide) has been used to disinfect drinking water in waterworks since the mid-1950s. Complex and expensive equipment is used there for its production, which is now no longer necessary. Simply produce the effective chlorine dioxide yourself and benefit from the perfect effectiveness against E.Coli, Pseudomonads and Legionella!

Disinfect drinking water pipes, dispensing systems and tanks in mobile homes, camping vehicles and on boats and yachts in compliance with the law.  Germ-free drinking or process water for industry and commerce can be easily implemented with the concentrates of biostream® GmbH - contact us. Our products are also suitable for the disinfection of drinking water in times of crisis, for emergency preparedness in case of blackout, power failure and other catastrophic events.


The biostream® products ZERO and asepticaPRO comply with DIN 2001-2:2009-04 (drinking water supply from small systems and non-stationary systems) and they are effective over the entire drinking water pH range. Hydrogen peroxide is not mentioned in the DIN as a disinfectant - also in the current UBA list of the Federal Environment Agency hydrogen peroxide is only mentioned as an oxidant - but not as a disinfectant.

Take a look at the label of the disinfectant you are currently using: If you find hydrogen peroxide as the active ingredient there, then according to the Federal Environment Agency you are NOT using a DISINFECTING AGENT but an oxidizing agent which, according to DVGW worksheet W291, must be dosed 25 X more strongly in order to achieve the same effectiveness as the active ingredient in the biostream® products.

And if your product also contains silver: Silver is also not mentioned as a disinfectant but only as a preservative. In addition, the following note on this can be found in the DIN: "Only in exceptional cases when storing drinking water without consumption for a longer period of time. Preservation does not replace any necessary disinfection of drinking water that is not in perfect condition."
