Technical Information D10 UV GERMICIDAL DOSE (Required for a 90% reduction rate of various micro-organisms) UV DOSE The relationship between dose and kill rate is a logarithmic value as demonstrated for e-coli below. The D10 UV dose received by the organism is dependent on:  Output power of the arc tube  Geometry of the irradiation chamber  Residence time within chamber e.g. E.coli (a major water borne pathogen) D10 =5.4mWs/cm2 Dose (mWs/cm2) Reduction (Log) 1 x D10 5.4 90% (1) 2 x D10 10.8 99% (2) 3 x D10 16.2 99.9% (3) 4 x D10 21.6 99.99% (4) Bacteria D10 Dose Bacteria D10 Dose Agrobacterium Tumefaciens 4.2 Phytomonas Tumefaciens 4.4 Bacillus Anthracis 4.5 Proteus Vulgaris 3 Bacillus Enteritidis 4 Pseudomonas Aeruginosa 5.5 Bacillus Megaterium (spores) 1.1 Pseudomonas Fluorescens 3.5 Bacillus Paratyphosus 3.2 Salmonella Enteritidis 7.6 Salmonella Paratyphi (Enteric Bacillus Subtilis (spores) 12 Fever) 6.1 Clostridium Botulinum 12 Salm
