<p>The invention concerns a method for arrangement of the water circulation in a paper mill, which paper mill comprises a pulp manufacturing plant provided with a water circulation system, such as a TMP plant, and a paper machine provided with a water circulation system. In the invention, in view of reducing the amount of fresh water supplied to the paper mill, a part of the amount of fresh water supplied to the paper mill is substituted by water or waters cleaned locally from waters contaminated at the paper mill. The concentrate or concentrates obtained from the stages of water cleaning is/are utilized where applicable by arranging said concentrate(s) to flow upstream in relation to the raw-material flow for reuse at the paper mill. By means of these operations the level of the amounts of interfering substances circulating in the paper mill is controlled.</p> |
