Kemira’s FennoBrite products are a wide range of chelating agents and bleaching enhancers that can be used in the bleaching processes of chemical, mechanical, and deinked pulp. FennoBrite is an excellent solution in closed water circulations and for zero-effluent mills (when utilizing an evaporation plant for water treatment and recovery boiler for caustic).
FennoBrite stabilizer formulations provide tailor-made solutions for optimizing peroxide performance in mechanical, chemi-mechanical, and recycled pulp bleaching as well as for stabilizing oxygen-based bleaching chemicals in chemical pulp bleaching. With FennoBrite bleaching enhancers, the use of actual bleaching chemicals like hydrogen peroxide is more effective, enabling chemical savings.
FennoBrite has many benefits compared to sodium silicate that is traditionally used as a peroxide stabilizer:
- silicate-free polymer and non-polymer based bleaching enhancers
- ensure efficient circulation of filtrate without scaling problems
- reduce cationic demand in the downstream process
- achieve energy savings in wash presses and drying sector (due to better dewatering)
FennoBrite chelating formulations provide tailor-made solutions for managing particular metals in pre-bleaching, bleaching, and post-bleaching.
