Abstract:This thesis is based on seven publications dealing with separation processes applied in the manufacturing of chemical pulp. The first part discusses the correlation of mass transfer phenomena in the ultrafiltration of spent cooking liquor. The second part focuses on the fiber mat formation that takes place in pulp washers and thickeners.
