Studies of the factors influencing the flocculation and sedimentation of microbial cells in the treatment of Kraft mill effluents

The treatment of paper mill effluents involves a succession of unit processes to remove the impurities that may vary in size by about six orders of magnitude. process of primary importance in this study The unit was the biological treatment stage, where an understanding of the flocculation and sedimentation of micro-organisms is needed in order to operate it efficiently.
