Abstract

The invention relates to a method for treating liquid flows at a chemical pulp mill. The system comprises a cooking process for producing pulp, at least one washing stage for washing the pulp, at least one bleaching stage for bleaching the pulp, a waste water treatment plant (40), a raw water treatment plant (30), and a wood processing unit (50), and the method comprises conveying at least a portion of low chloride content process waters to the chemical pulp mill in order to be reused as process water. In addition, the invention relates a system for treating liquid flows at a chemical pulp mill and a use of low chloride content process waters at a chemical pulp mill.
