UV (Ultra Violet) TreatmentTypical UV disinfection systems involve the flow of water through a vessel containing a UV lamp as shown in Figure 1. Ultraviolet (UV) light is electromagnetic radiation traveling in wavelengths in all directions from its emitting source (bulb).
UV-C light deactivates the DNA of bacteria, viruses and other pathogens, which destroys their ability to multiply and cause disease.
Bacillus anthracis Corynebacterium diphtheriae Dysentary bacilli (diarrhea) Escherichia coli (diarrhea) Legionella pneumophilia Mycobacterium tuberculosis Pseudomonas aeruginosa Salmonella (food poisoning) Salmonella paratyphi (enteric fever) Salmonella typhosa (typhoid fever) Shigella dysentariae (dysentery) Shigella flexneri (dysentery) Staphylococcus epidermidis Streptococcus faecaelis Vibro commo (cholera) Bacteriophage (E. Since natural germicidal UV from the sun is screened out by the earth's atmosphere, we must look to alternative means of producing UV light. Suspended solids or particulate matter can cause a shielding problem in which a microbe may pass through the UV filter without actually having any direct UV penetration.

This damage prevents the microorganism from multiplying or replicating in a human or animal host. The most effective wavelength frequency, from the point-of-view of microbiological disinfection, is 254 nm as this is where the optimum energy intensity is found.
The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. Electrons flow through the ionized mercury vapor between the electrodes of the lamp, which then creates UV light. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
