• How Do You Know If Your Ozone Contacting System Is Well Mixed?

  Mixing is something that is often taken for granted when designing systems for water and wastewater treatment. Perhaps “taken for granted” is too harsh a term. Let’s instead say that while designing a treatment unit operation or process, mixing as a phenomenon is automatically assumed to occur – an assumption that forms the basis for process controls, performance guarantees and measurement methods and locations.
