  • Why is ozone a nanobubble?
  • When ozone is delivered as nanobubbles, it increases the retention time due to the low-rising-velocity-related low buoyancy and increased higher specific area of nanobubbles compared to those of ordinary bubbles. The diffusion and concentration of ozone in the water are very important in the treatment process.
  • Can nanobubbles improve water and wastewater treatment processes?
  • In this context, nanobubbles (NBs), with its many unique characteristics, have been receiving growing interest in various fields of application, as they offer great opportunities to improve existing water and wastewater treatment processes in various dimensions.
  • How does decomposition of ozone in water generate oxygen?
  • Decomposition of ozone in water generates oxygen where higher oxygen concentrations are obtained using nanobubbles. The oxygen formed during decomposition of ozone generates radicals that can oxidise pollutants.
  • What are the disadvantages of conventional ozone treatment?
  • The main drawbacks of using conventional ozone methods are the high-buoyancy-related low retention time and rapid decomposition of ozone eradicating residual ozone in water, which do not support prevention of regrowth of microorganisms in treated water.
