Facts that speak for us
With the biostream® concentrates based on chlorine dioxide, you reliably disinfect drinking water tanks, water-carrying pipes and soda maker bottles, with the active substance used by waterworks, without costly plant technology.
The active substance chlorine dioxide has been used to disinfect drinking water in waterworks since the mid-1950s. Waterworks use elaborate and expensive plant technology that is no longer necessary. Produce effective chlorine dioxide yourself, quite simply, and benefit from its excellent efficacy against E. coli, pseudomonads and Legionella.
Disinfect drinking water pipes, dispensing systems and tanks in motorhomes, camping vehicles and on boats and yachts in compliance with the law. Germ-free drinking or process water for industry and trade can also easily be achieved with the concentrates from biostream® GmbH. The products are also suitable for disinfecting drinking water in times of crisis, for emergency preparedness for blackouts, power cuts and other disaster situations.
Hydrogen peroxide and silver-based agents are not an alternative
The biostream® products ZERO and asepticaPRO comply with DIN 2001-2:2009-04 (drinking water supply from small and non-stationary installations) and are effective across the entire drinking water pH range. Hydrogen peroxide is not named as a disinfectant in the DIN standard. In the current UBA list of the German Environment Agency, too, it is listed exclusively as an oxidising agent.

Check the label of your current product: if you find hydrogen peroxide listed as the active substance, then according to the German Environment Agency you are using not a disinfectant but an oxidising agent, which under DVGW code of practice W291 must be dosed 25 times more strongly to achieve the same effect. Silver, too, is listed only as a preservative, not as a disinfectant. The DIN standard notes: "Only in the exceptional case of storing drinking water without consumption over a longer period. Preservation does not replace a necessary disinfection of drinking water that is not in perfect condition."
