UV disinfection

Principle

For many years, protecting water has become a necessity. Water is exposed to various sources of pollution which are difficult to control. In addition, it is imperative to improve the quality of consumed and discarded water.
The presence of pathogenic micro-organisms in water is hazardous to consumers’ health. Agriculture, farming and industry also need solutions to improve the quality of their drinking water.
Ultraviolet radiation at the specific wavelength of 253.7 nanometres inactivates pathogenic micro-organisms within seconds, causing photochemical reactions on their DNA (deoxyribonucleic acid). An abnormal link is created on the DNA chain of the bacterium which loses its ability to reproduce. Cell division fails to occur and the micro-organism becomes harmless.

Advantages:

1. No change in the chemical composition of water, or in its organoleptic qualities
2. No chemical addition
3. No formation of toxic by-products
4. Safety for users who do not have to handle hazardous products
5. No worry with quantities
6. Consistency of performance in all seasons
7. Very short contact time (few seconds)
8. Moderate cost: operating costs concern changing lamps and power consumption only
9. Maintenance: it is limited to changing lamps
10. No pH dependence
11. No additional corrosion due to reagent over dosage
12. In the case of industrial use, no risk of adverse reactions
13. More effective action than chlorine on some viruses and bacteria

Regulations

1. The dose recommended by the General Department of Health (Circular of 19 January 1987) is 25 mJ/cm2 minimum for consumption water
2. For designing our UV sterilizers we apply the biodosimetry method and the dose of 40 mJ/cm2
3. The effectiveness of our sterilizers has been determined by biodosimetric testing; some examples:
4. GERMI AD 200 - Flow 14 m3 / h: 40.0 mJ/cm2 (98% permeability)
5. GERMI BD 120 - Flow 25.5 m3 / h: 40.0 mJ/cm2 (98% permeability)
6. GERMI BD 200 - Flow 40.6 m3 / h: 40.0 mJ/cm2 (98% permeability)
7. GERMI CD 120 - Flow 50 m3 / h: 40.0mJ/cm2 (98% permeability)
8. GERMI CD 200 - Flow 87 m3 / h: 40.0 mJ/cm2 (98% permeability)

Applications

1. Distribution of drinking water: the municipalities.
2. Disinfection of water treatment plants.
3. Public and private pools, thalassotherapy.
4. Private catchments: wells, drilling, river bailing.
5. Irrigation: greenhouses.
6. Farming: poultry and pigs are sensitive to chlorine.
7. Hospitals, hotels, campgrounds, restaurants.
8. Agro-food industries: meat and fish, beverage and canning industries.
9. Fish farming, aquaculture, fish farms and large aquariums.
10. Electronics industry, chemical and mechanical.
11. Air Treatment (clean room, laboratory ...)
12. Disinfection of mats, food containers, cutting tools, laboratory equipment.

Equipment

A diverse range of equipment is available according to your application, hydraulic flow and processing requirements (reduction of bacteria). Our ultra violet instruments are available in several models.
