A stochastic model of an ozonation reactor.

摘要: Disinfection of some microorganisms is characterized by a lag-phase (a minimum required ozone exposure until disinfection occurs). This phenomenon easy to model in laboratory batch reactors but not continuous flow mixed reactors. paper introduces stochastic where individual are followed on their paths through full-scale Combining exponentially distributed transport processes with delayed exponential kinetics for large populations (up 10,000 individuals) yields predictions which can be evaluated statistically. It could shown that deterministic models work well systems good performance (more than 2 log units reduction active microorganisms), poor have applied. demonstrated real Bacillus subtilis spores surrogates Cryptosporidium parvum oocysts. The differences between the two deviate significantly from plug-flow behaviour.
