Reactors for dissolving ozone in liquid

Information on Korona reactors which are used to dissolve ozone in liquids

Reactors

Most industrial mass transfer processes consists in penetration of a component or several components from one phase to another through the interphase: extraction, absorption, distillation, drying, etc.
Mass transfer during penetration covers the following three stages:

  1. Mass penetration from the inside of the first phase to the interphase, i.e. to the film at the junction of ozone and liquid.
  2. Transfer of mass through the interphase – through the film.
  3. Mass penetration from the interphase to the inside of the second phase – from the film to the liquid.

The process of dissolving gas in liquid (but unfortunately not ozone) is described by Henry’s law. The interested may reach for extensive literature; this process is perfectly modelled mathematically and described well as the main section of chemical engineering.

Ozone diffusion into water is just such a process – the mass transfer process. However, it essentially breaks off from the mathematical and engineering model described for other systems. Why? Ozone decomposes (disproportionates) into atomic and molecular oxygen all the time. The half-life of ozone in both air and water cannot be described by the equation known from the theory of the disintegration of radioactive elements. The decomposition rate constant is not … “constant”. Therefore, Fick’s laws and Henry’s law do not have a precise application. Subject, ozone diffusion theory is erroneously described in the literature. The lack of a good mathematical apparatus for researchers eliminates their achievements of practical applications. Well … theories are wrong. Therefore, research in our laboratory was aimed at improving this. We made a few discoveries but, because we make a living on mass transfer, they are not published and kept secret. Through our own research in the laboratory, we put them into practice, without any major obstacles, to industrial applications. Our reactors have an unprecedented efficiency. The geometry of the reactor, the size of ozone bubbles and its concentration are important. This knowledge is generally accessible, but proportions are our discovery.
