Ozone is a toxic gas generated by applying a high voltage to oxygen. The first commercial use of ozone for bleaching was in 1992, so ozone is relatively new for pulp bleaching. However, ozone provides several economic and environmental benefits over other chemical options for elemental chlorine free (ECF) and totally chlorine free (TCF) bleaching. This course discusses the benefits of ozone bleaching, its chemistry, how it is generated, and the process and equipment involved in ozone bleaching.

At the end of this module, you will be able to:

  • State the benefits of ozone bleaching (compared to other chemistries)
  • Describe ozone bleaching chemistry
  • Explain how ozone is generated
  • Explain how ozone bleaches pulp
  • Identify important ozone bleaching variables
  • Identify and describe ozone bleaching processes and equipment
  • Identify and describe safety hazards and safe work practices associated with ozone bleaching

The following key questions are answered in this module:

How is ozone generated?
Ozone is created by applying high voltage to a gas that contains oxygen.

What are the advantages of ozone bleaching?
Ozone provides several economical and environmental benefits over chlorine dioxide and other bleaching chemicals. It can be formed from oxygen, it is a strong oxidizer, and reacts quickly with pulp.

Does ozone bleaching require special equipment?
Yes, the equipment depends on the pulp consistency. High consistency is most popular today. A special horizontal reactor is used instead of a large conventional tower because the reaction is fast. A wash press, or similar equipment, is needed to achieve high consistency.

What process variables are important for ozone bleaching?
Temperature, pH, consistency, and mixing all impact the efficiency and selectivity of ozone bleaching.

Is ozone hazardous?
Ozone is toxic even at low concentrations and at high concentrations it can explode. The concentration of ozone gas in air must be continuously monitored.

Below is a transcript of the video sample provided for this module:

Because ozone gas is unstable and cannot be stored, it is manufactured-on-demand. Ozone is created by applying high voltage to a gas that contains oxygen. For pulp bleaching, pure oxygen is used so a high concentration, 10 to 12% of ozone can be generated. Electrons travel across a gap between electrodes. When oxygen molecules collide with the electrons, they break apart into individual oxygen atoms. The individual atoms attach to molecular oxygen and form ozone.

Customer Q&A

Ask a Question

Sorry, we're missing some information

How do I log in to watch a video that I have already paid for?

Easy! Moments after you purchase your pay-per-view (PPV) course, you'll receive an email with login details. Just click the link and log in with your user name and password and you're on your way!

I would like to have some of my employees take 5 of your driving related courses, how can i set this up?

We're in the process of making bulk purchases and purchases for multiple users easier. But for now, you can order multiple courses and just let us know who you'd like to assign courses to. With an email for each user, we can set up their training plans and make sure everyone gets the eLearning assignments they need.

How can I get your paper-making courses for free?

Well, we can't blame you for asking... And while we're a for-profit company, there are situations with students and certain educational organizations where we can help out with a selection of eLearning. However, our online courses are extremely economical. And our paper industry courses are in very high demand. So, without knowing more about your situation, we think you'll get loads of value from the $39 you'll spend on any of our premium courses.

Do you have eLearning in Portuguese?

Yes, we do! And in addition to primary English narration, we produce many courses in a growing number of languages, including Spanish, Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Russian, Tamil, and Thai.

I'm unemployed, but I really like your eLearning. Do I get a certificate when I complete a course?

Yes! All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of eLearning. In the future, we'll have badges for you to use in your LinkedIn profiles.
