Cleanroom Decontamination

Cleanrooms need to be completely free of environmental pollutants and this includes all type of biological contaminant whether airborne or present on surfaces. If cleanliness is compromised or if a facility has been shut down for routine maintenance, modification or refurbishment, then biological decontamination will be necessary and needs to happen quickly and efficiently.

Using a reliable and validated room bio-decontamination service will reduce the risk level of your product to be compromised.

We offer clean room decontamination services using ionized Hydrogen Peroxide equipment.Our disinfectant is a liquid containing 7.9% of hydrogen peroxide (H2O2)in distilled water spiked with 30 ppm of colloidal silver.

The liquid product is transformed into a dry fog during the spraying phase. The combination of speed and temperature during spraying ionizes the emitted particles and degrades the peroxide into highly oxidizing free radicals very short-lived. No volatile organic compounds are generated.

In this non-wetting fog, the particle size (5µn on average) ensures a slow and perfectly uniform sedimentation on every square centimetre of the treated premises with no humidity and without leaving any residues.

Mode of action:

The concept of this disinfection is that it causes the germs to self-destruct.Therefore, it can be used on a daily basis without creating any form of bacterial resistance.

The bactericidal action of the concept is due to the production of hydroxide (OH-)radicals that transfer their electrons to the bacterial membrane, changing its polarity. The electroporosity of very low doses of silver (used as catalyst) is such that all the peroxide will be immediately transformed into hydroxyl radicals. Once the electron has been lost, H2O2 will recombine into dioxygen (O2), Water (H2O) and dihydrogen (H2).

Action on bacteria:

  1. Irreversible changes in bacteria membrane permeability
  2. Bacteria self-destruction

Action on spores & yeasts:

Confirm that the HEPA filter, or its frame, is not damaged or improperly placed during installation. A properly applied HEPA filter produces a fairly uniform discharge of air velocity and direction.

Action on viruses:

Enveloped viruses:

They have an envelope with characteristics quite similar to those of bacteria, and glycoproteins which are very susceptible and very easily inactivated by the hydroxyl groups (OH-).

Naked viruses: 

  • With helical symmetry, the action targets the capsid which is depolarized,disrupting the helical chain 
  • Icosahedric viruses: the action targets directly the capsomers by breaking the pattern of the polypeptidic chains. 

DNA viruses: 

The exposure time is a little longer but the response is excellent.

Interest to perform clean room decontamination:

  • Efficiency: Reduce microbial contaminants to below detectable levels. Consistent and robust performance against all types of organism including those considered difficult to deactivate.

  • Speed: fast decontamination cycles reduce plant downtime and minimize operating costs. After decontamination process, the cleanroom can be ready for use in as little as one hour.

  • Non-hazardous solution: breaks down quickly after the decontamination process. Does not attack plastics and painted surfaces and does not damage the electronics or other sensitive equipment within your room.


The effectiveness of the concept was demonstrated through bactericidal, fungicidal, sporocidal and virucidal tests.
