O3 bleaching is one of the key alternatives for TCF (Totally Chorine Free) or ECF (Elemental Chlorine Free) pulp production
Thanks to ozone bleaching combined with oxygen delignification and other nonchlorine bleaching technologies, mills can curb emissions and meet environmental standards costs. This process favours a higher percentage of recycled process water, lowers chemical oxygen demand discharges, and reduces colour in the mill waste.
Benefits
-Alternative to chlorine and chlorine dioxide.
-Reduction of AOX.
-Reduction of wastewater O2 requirement and effluent colour.
-Higher process water recycling rates.
-Used for total chlorine-free pulp production and mill closure.
