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.
