Valmet provides state-of-the-art bleach plants for all commercial pulp grades, i.e. chemical, dissolving and mechanical pulps of softwood and hardwood. Valmet’s bleaching plants are customized to meet each pulp mill's unique needs.

Bleach plant designs are optimized to produce the desired pulp quality at minimum cost and minimum environmental impact. You achieve high pulp quality, low consumption of chemicals and energy as well as minimal effluent load.

Bleaching of chemical pulp

The key success factors in bleaching chemical pulp are effective mixing of bleaching chemicals into the pulp, well-defined retention times in bleaching reactors and barrier washing between bleaching stages. Barrier washing results in low chemical consumption, low effluent flows and the possibility to operate at zero fresh water consumption.

Bleaching of dissolving pulp

Valmet provides state-of-the-art concepts for bleaching dissolving pulps. We assist you in achieving higher pulp quality, production efficiency and environmental friendliness.

Sappi Cloquet: New MC ozone mixer - when less becomes more

Challenging the conventional approach of using two ozone mixers for pulp bleaching was worth it. As the first company using the new MC ozone mixer technology, Sappi Cloquet’s mill can now benefit from lower investment, maintenance and power consumption costs – and all this with only one mixer.

Smooth transition to new bleaching line

A new bleaching line project for one of the world’s biggest pulp producers exceeded expectations in many fronts and received a provisional approval in record time thanks to excellent project planning.
