Ozone bleaching is a chlorine-free bleaching method. This method is safe and reliable, and can eliminate AOX and COD in wastewater. Ozone bleaching is also more efficient and stable.
What is the role of ozone in the bleaching process? When the ozone concentration is high, ozone can fully combine with the pulp, which is beneficial to improve the bleaching efficiency of ozone on the pulp and the whiteness of the final pulp products.
What is an ozone generator? An ozone generator is a device designed to produce the gas ozone. Ozone is used effectively in water purification, but ozone in air must reach high levels to remove air pollutants. Health experts warn that it is important to control conditions to ensure that no person or pet becomes exposed to high levels of ozone.
What is the pulp concentration for ozone bleaching? In the application of ozone bleaching, ozone concentration, pulp concentration, pH value, bleaching temperature, bleaching time, additives and others will affect the bleaching effect. The pulp concentration for ozone bleaching can be divided into low, medium and high, corresponding to 3%, 10-15% and 30-50% respectively.
Can I use an air purifier that is not an ozone generator? Afterward, using an air purifier that is not an ozone generator could be a good option to try. There are different types of air purifiers out there, from mechanical filters (like HEPA) that only remove particles from the air, or gas-phase filters like carbon filters that are only designed to remove VOCs.

Should you use an ozone generator? Why Use an Ozone Generator?
- Eliminates Odor: For many days, you might be living in an uncomfortable environment.
- Water Purification: For many years now, an Ozone generator has been used for water purification.
- Effective and Reliable: An Ozone generator is not like any other air purifier because it works effectively.
Can I use an ozone generator in a car safely? Run the ozone generator at full power for at least 30 minutes but no longer than two hours. No one should be in the car during this process. No animals should be in the car during this process. Do not run the generator longer than the recommended time. Air out the vehicle to allow the ozone to dissipate.
Are ozone generators beneficial in homes? The negative aspects of ozone generators definitely outweigh any potential positive benefits, and it is best if you consider safer and more effective solutions for improving your indoor air quality. Manufacturers of ozone generators often make false claims about their devices and say they are effective at odor removal.
Why are ozone generators bad? Are ozone generators bad for the environment? Environmental ozone causes more damage to plants than all other air pollutants combined. Similarly, ozone generators can damage plants in indoor environments. High levels of ozone will inhibit the ability of plants to open the microscopic pores on their foliage and breathe.
What is the role of ozone in the bleaching process?
How does ozone bleaching work? Ozone bleaching at medium pulp consistency features a pump that feeds the pulp into usually two ozone mixers in series, a pressurized reactor (used mainly as a buffer) and a blow tube. An ozone compression step is required because of the large amount of gas that needs to be injected so ozone (and oxygen) is compressed to 7-11 bar (g).
What is Ozone used for? Ozone is used worldwide on every continent—in ECF bleaching and TCF bleaching, on kraft and sulfite pulps, on hardwood and softwood pulps, and for pulp grades used in all sorts of end products such as tissue, printing and writing paper, viscose, and more.
What is the technical challenge of pulp bleaching with ozone? The technical challenge of pulp bleaching with ozone is to homogeneously mix pulp and a large amount of gas in very little time. Ozone is very reactive, so mixing homogeneity is important to avoid pulp quality discrepancies; ozone is unstable and decomposes quickly into oxygen, so it should be applied in a short amount of time.
What factors influence the final choice of ozone bleaching? Economics are usually the main factor influencing the final choice of ozone bleaching, but environmental aspects are also considered.
