The subject of this paper was to consider the possibilities of economical paper production with rationalization of water consumption. In accordance with the principles of viable development. The pulp & paper industry has had to face global market needs and strict regulation concerning the environment. The basic motive was to provide consistent and high product quality, which is competitive on the market. The pulp & paper industry is one of the largest consumers and pollutants of natural resources. In that light, the rationalization of raw material, water, energy and chemicals consumption with minimization of environmental impact is essential. The European directive on environmental protection obliges producers of pulp & paper to decrease the volume of wastewater and to increase the efficiency treatment. Pulp and paper industry in Serbia and Montenegro will also be faced with the demands for environmental protection. Numerous examples of water consumption rationalization and improvement of water quality in the pulp & paper industry could be found in different literature sources. It is necessary to increase water system closure and implement up-to-date treatment methods. The possibilities for water consumption rationalization, in a real system the paperboard mill UMKA, were examined.
