Combat biofilms, viruses and bacteria with biostream® products.

Biofilms as a source of pathogenic germs

Behind the water meter, the water enters a pipe network, e.g. a domestic installation, in which usually no sanitation measures have been carried out since this network was built. The microorganisms in these pipe systems can thus lead to the formation of biofilms, which then show themselves in the presence of legionella, pseudomonads or other water germs (e.g. CFU units).


The problem: The biofilm

At this point, the biofilm must be taken into account, which, similar to an anchor, prevents the microorganisms from being flushed out of the piping system and provides them with a „flow protection“ for unhindered multiplication. The biofilm performs this task for both non-pathogenic and pathogenic germs.
Only the following factors are required for the formation of a biofilm:

  1. A surface in contact with water
  2. Sufficient water
  3. Microorganisms
  4. nutrients

The surface in contact with the water is the copper pipe, the drinking water hose, but also the surface of beverage dispensers that come into direct contact with the drinking water. The nutrients are present in the water in the form of humic acids, microorganisms and degradation products of biofilms.

The formation of a biofilm even in newly laid and cleaned pipes takes place in a very short time and can be divided into six phases.
In our PDF-Document about biofilms (in German language only) you can view the individual steps in detailed illustrations.

Basic knowledge about drinking water

In just 5 pages, we explain which products are approved for disinfecting drinking water and why products containing silver now have to be labelled as pesticides in the USA.

Did you know?

Hydrogen peroxide is not an approved drinking water disinfectant. According to the UBA list (annex to the Drinking Water Ordinance), hydrogen peroxide is only listed there as an "oxidant" and not as a "disinfectant".

dr-werlein​LEIBNIZ UNIVERSITY OF HANOVER CONFIRMS EFFICACY

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.

biofilm-uni-hannoverSUSTAINABLE CONTROL OF LEGIONELLA AND BIOFILMS

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.

 

FROM SMALL CONTAINERS TO TANK TRUCKS - THE CHOICE IS YOURS!

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.

HYDROGEN PEROXIDE AND AGENTS CONTAINING SILVER ARE NOT AN ALTERNATIVE

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."
