PE = log (e) = 1/n logK log (Red)/(Ox) or Eh = 23 RT pE / F The pE provides a nondimensional scale (like pH) that expresses the activity of electrons in factors of 10 Eh, called the redox potential, is measured in volts F is the Faraday constant, which is the electric charge of one mole of electrons (96,500 coulombs) F has aThe log reduction is a mathematical term used to express the relative number of living microbes eliminated by a disinfectant In scientific papers a 1 log10 reduction – this is more commonly written as 1log – corresponds to inactivating 90% of a target microbe with the count being reduced by a factor of 10As a rule of thumb, for every additional Log Reduction number, you add the number 9 to the percentage reduction, so a Log Reduction of 30 Log is a 999% reduction compared with a Log Reduction of 60 Log which is equivalent to a % reduction Below is an example of Log Reduction values using a starting point of one (1) million bacteria or 1,000,000 Describing Water Tre...
