Ozone produced electrolytically

ELECTROLYTIC OZONE PRODUCTION

Ozone can be produced directly in water using electrolytic ozone generators. This has huge advantages as the contacting equipment normally required for dissolving ozone gas into water is not required.

Electrolytic Ozone Generator

Electrolytic ozone generators use an electrical discharge in the water to split the water molecule (H2O) into H2 + O2. This O2 can also be split into O and combine to create O3. This will require a method to isolate oxygen from hydrogen and electrically charge this oxygen into ozone. Much work has been done working with catalysts, anodes and cathodes to improve efficiencies. However, this method is still unreliable in any water other than ultra-pure water, and is energy inefficient.

 ADVANTAGES OF ELECTROLYTIC OZONE GENERATOR

  • Ozone produced directly in water, no ozone contacting equipment or off-gassing equipment required
  • Compact design and size

DISADVANTAGES OF ELECTROLYTIC OZONE GENERATOR

  • High energy consumption
  • Short life of anode and cathode used for electrical discharge

Ozone Production – How Ozone is Produced

Ozone produced naturally from UV-Light

The most common place in our world to find ozone is the ozone layer. This is a natural and important part of our word. UV light will create ozone from atmospheric oxygen at short wavelengths of less than 240 Nanometers (nm). UV light will also destroy ozone and break ozone back down into atomic oxygen (O) and diatomic oxygen (O2) at wavelengths from about 200 nm to 315 nm. Therefore, the ozone layer does a great job filtering UV wavelengths from about 100 – 315 nm. This is important as these are the harmful wavelengths of UV light cause sunburn in humans, and DNA damage in living tissues.

The ozone is an important part of our worlds stratosphere. The level of ozone in the stratosphere ranges from 2 to 8 ppm in the ozone layer, therefore most of the atmospheric oxygen remains in the diatomic form (O2). Another element of pollution that is commonly discussed is the potential to disrupt this balance of ozone production and destruction via UV light in the stratosphere.
