The result is a prolonged, deep and capillary sanitization. The
energetic sanitizing action combined with the wide spectrum of action and effectiveness, the speed
and simplicity of application and the absence of incompatibility with most materials make
BIOSAN K13 an economical and versatile environmental sanitizer when a preventive treatment is
required to control the development of infections and diseases in the environment. The product
also stops fermentation and is repellent for insects. It is not corrosive and after use and aeration of
the environment it does not add any odor (1 *). Normally, for the sanitation of 100 m3 of the
environment 3 liters of 33% liquid formaldehyde with 3 kg of potassium permanganate are used.
The exothermic reaction that develops produces about 99 grams of formaldehyde which remains
active for about 32 minutes. With a tablet of BIOSAN K13 about 400 gr (600 lt) of gaseous
formaldehyde are produced which remains active for about 6 hours.
Sectors of use: it can be used in farms (chickens, turkeys, rabbits, pigs, etc.) for the sanitation of
environments, and cages, hatcheries, warehouses and equipment; in agriculture for the treatment
of feed storage silos; for the treatment of means of transport for animals (railway wagons and
trucks, ship holds, cold rooms) and all closed environments that require radical sanitation.

1. * The olfactory residuality depends on the porosity of the materials present in the environment. Normally it is negligible in environments intended for breeding

Composition: paraformaldehyde: 40%; excipients: 60% Instructions for use and dosage: on average one tablet is sufficient to treat 700 M3 of environmental volume to be treated. Method of use 1.Protect any equipment present and close the environment. Disengage the ventilation systems. 2. Check that the relative humidity in the environment is at least 65%. 3. Light the tablet with a gas burner or with the aid of alcohol to be poured on the tablet (approximately 15 ml). 4. Wait for it to turn completely black (3 to 5 minutes). 5. Smother the flame by covering it. 6. Wait for fumigation until complete consumption.

This is due to both the low molecular weight of formaldehyde and the inability to return to the solid state (condensation) due to exposure to low environmental temperatures or contact with cold surfaces. This last aspect is of significant importance as only in the gaseous state does the active ingredient interact optimally with the pathogens for the necessary contact time and then decompose without leaving a significant residue. Other active ingredients with higher molecular weight, such as for example Ortophenylphenol (OPP) effectively used in our other fumigant tablets, which are in the registration phase (PT3 & PT4) are not suitable for the production of tablets for the treatment of large volumes with a few pieces. In this case, it is preferable to use several medium-sized tablets uniformly arranged in the environment rather than a few large tablets. This approach associated with an adequate heat input of appropriate duration throughout the fumigation allows the diffusion and maintenance in the gaseous phase of active ingredients of higher molecular weight that are more difficult to vaporize compared to formaldehyde.. Advantages:

• Simply: no specific application equipment is required.
• Effective: fumigation guarantees a highly effective and prolonged action thanks to the anhydrous gas (formaldehyde) that penetrates into every nook and cranny.
• Stable: the formulation in solid tablet form avoids the separation of components during transport which can occur in powder formulations, risking to compromise their performance.
• Performant: 1 tablet (1300 g) allows the treatment of about 700 M3. The characteristics of the active principle in the gaseous state and the peculiar production process have made it possible to create and propose for large environments a tablet as effective as the 700 g one (BIOSAN K) which, however, allows to halve the application points with a further saving of 50% of the operator time.
• Safe: the application requires no operator effort except for the start-up phase (saving time, personnel, elimination of exposure risk): once positioned and switched on, 90% of the work is done (no more than 5 min. Per tablet). During activation (ignition and suffocation) use a protective mask for organic fumes (formaldehyde)
