biostream® PERMAGNA for disinfection of pool, SPA and bath water

Control biofilms and drinking water bacteria (E.Coli, Legionella and Pseudomonas) in swimming pools, whirlpools and medical baths with biostream® PERMAGNA.

biostream® PERMAGNA is not only characterized by an excellent antimicrobial efficacy profile, but also possesses optimal properties from the point of view of application technology:

In addition to the excellent disinfection properties of biostream® ZERO, PERMAGNA has a depot effect for long-term disinfection.

biostream® PERMAGNA is an alkaline disinfection solution that can be used in acidic, neutral and alkaline environments without any problems – coupled with its extraordinary disinfection effect without germ resistance formation.  Thus, biostream® PERMAGNA is perfectly suited for effective disinfection of water in pools and spas.

Fungi, algae, viruses and pathogenic germs are effectively combated and killed by the active ingredient approved for drinking water. In technical terms, these germs are called pseudomonads (Pseudomonas), E.Coli and Legionella.

The outstanding properties of biostream® PERMAGNA for the disinfection of water in swimming pools, whirlpools and medical baths:

  • Broad-spectrum disinfectant
  • In-situ production of chlorine dioxide directly in the water to be treated
  • Killing of legionella, pseudomonads, E.Coli, viruses and algae#
  • COD/TOC/BOD reduction
  • Increase of the redox potential
  • Detoxification by hydrolysis and oxidation
  • Fat splitting and desulfurization
  • Removal of odors
  • Fecal matter elimination



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".

Wir erklären Ihnen auf nur 5 Seiten, welche Produkte zur Desinfektion von Trinkwasser zugelassen sind und warum silberhaltige Produkte in den USA mittlerweile als Pestizid gekennzeichnet werden müssen.

Pool desinfizieren

biostream® PERMAGNA can be intelligently expanded through modular design:

biostream® PERMAGNA can be easily extended by adding components. For example, lime deposits can be combated or corrosion can be further reduced. 

Highly concentrated and ready for immediate use:
PERMAGNA does not need to be activated and is therefore ready for immediate use. The active ingredient chlorine dioxide is generated in-situ in the process water and is therefore immediately available in high concentration to combat Legionella, E.Coli and Pseudomonas. This effectiveness results from the high disinfection power of chlorine dioxide coupled with the disinfection effect of other chlorine oxide active ingredients.

Spa-Wasser desinfizieren


biostream® PERMAGNA is dosed directly from the delivery container.

Thus an immediate disinfection is possible. Dosing can be done manually or by means of a dosing pump. The appropriate dosing technology is available directly from our technology partner. Since only low outgassing occurs during dosing (MAK value), biostream® PERMAGNA can be added directly from the delivery container to the water to be disinfected without any problems or technology.

Our practical experience has shown efficacy against E.Coli, Legionella and Pseudomonas in the following concentrations:

Swimming pool water: 5 ml/m3 per day.
whirlpool: 10 ml/m3 per day

The pH value of the water to be treated should be between 4 – 10.


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.
