Abstract
Recently, the paper factories within the country have shown the trends of merger and abolition and the surviving factories have been in the direction toward increasing in production. Therefore, and due in part to the expanded demand for wastepaper, the water situation around the paper factories stands, in general, facing a severe condition. The precondition for increasing in production is that there is an allowance for water usage, and therefore, for each factory, it is becoming an important theme to reduce the specific water consumption per unit paper product. With the objective of investigating on water saving, EBARA implemented surveys of water balance in two kraft pulp factories within the country on a total factory basis. Based on the results obtained in the above surveys, this article reports the features of water use and the point of effective utilization of water in the kraft pulp factories.
