Fresh pulp or pulp obtained from waste paper is the main constituent of paper. In order to meet the today´s requirements on paper in terms of its whiteness level, the pulp has to be bleached. Normally, hydrogen peroxide is used as the bleaching agent, and complexing agents are added to prevent its catalytic decomposition as a result of heavy metals dissolved in the process water. These products generally have poor biodegradabilities.

Baypure® CX100 is an environmentally friendlier, more effective and economical alternative. Its active ingredient – iminodisuccinate – is readily biodegradable and has higher efficiency than EDTA and DTPA in water with a high calcium content. These advantages are of particular benefit in the recycling of water, which is becoming more and more important in the industrialized countries.
