Imerys EcoBright™ is an ecofriendly, cost-effective solution for pulp bleaching.
Pulp bleaching is a necessary process for the production of both graphic paper and some packaging board grades. However, pulp bleaching continues to be an expensive process for the mill and process optimization is important for improved cost efficiency.
EcoBright™ is a stabilized magnesium hydroxide solution that is not only environmentally friendly, but delivers cost savings by ensuring optimized use of magnesium sulfate, caustic soda, silicate and/or hydrogen peroxide in the recipes.
Using Ecobright™ in pulp bleaching can achieve many benefits including:
- Higher final brightness values
- Improved pulp dewatering
- Lower anionic carryover to the paper machine
- Higher yield
- Fewer deposits
- Lower downtime
- Improved productivity
- Lower COD/BOD
- Cleaner effluents and water circuits
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
