Because column flotation offers many advantages over conventional flotation technology, we sought new applications for its use in the pulp and paper industry. One of them was the cleaning of whitewaters. We studied the performance of flotation column on a paper machine whitewater at the Bowater Gatineau mill: PM6's silo whitewater.
