biostream® PERMAGNA for the disinfection of process water

biostream® PERMAGNA – Disinfection of water-bearing pipes, water and process water according to VDI 2047

Highly efficient disinfection of process water with biostream® PERMAGNA in the area of cooling water circuits and large tanks – and wherever large quantities of water have to be disinfected effectively. Application according to guideline series VDI 2047 „Hygiene in recooling plants“.

biostream® PERMAGNA is not only characterised by an excellent antimicrobial effect profile, but also has optimal properties from the point of view of application technology: In addition to the excellent disinfection properties of biostream® ZERO or TRAVEL, 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 the formation of germ resistance – makes biostream® PERMAGNA the agent of choice when it comes to effective disinfection of water.

Recooling plants (cooling towers) can be a source of airborne germs. For this reason, the VDI has drawn up a summary in its guideline 2047 for operators to ensure hygienic operation. biostream® PERMAGNA is added directly to the cooling water in small quantities, where it kills algae, viruses and bacteria. This guideline VDI 2047 is a guideline for evaporative cooling systems and apparatus where water is trickled or sprayed or can otherwise come into contact with the atmosphere.

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


The outstanding properties of biostream® PERMAGNA for the disinfection of drinking water pipes, drinking water tanks and process water:

  • 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 through hydrolysis and oxidation
  • Fat splitting and desulphurisation
  • Removal of smells
  • Fecal matter elimination

Basic knowledge drinking water

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

biostream® PERMAGNA can be intelligently expanded thanks to its modular design:

biostream® PERMAGNA can be easily expanded by adding components. For example, limescale 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 immediately ready for 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 paired with the disinfection effect of other chlorine oxide active substances.

APPLICATION AND CONCENTRATIONS:

biostream® PERMAGNA is dosed directly from the delivery container. Separate activation as with biostream® ZERO is not necessary.

Therefore, immediate disinfection is possible. Dosing can be done manually or by means of a dosing pump. You can obtain the appropriate dosing technology 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.

Depending on the existing infrastructure (tanks, pipes, filters), different dosages are recommended. The quality of the source water also plays a not insignificant role. Our practical experience has shown effectiveness against E.Coli, Legionella and Pseudomonas in the following concentrations:

  • Cooling and process water: 5 ml/m3 – 25 ml/m3 (open systems from 30 ml/m3 to 160 ml/m3)
  • Basic sanitation of drinking water pipes: 30 to 60 ml/m3

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

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."
