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.
