Positive examples of wastewater treatment effectiveness in ‘Natron-Hayat’ Maglaj factory

Abstract

In the paper are described the basic characteristics of wastewaters in the cellulose and paper factory ‘Natron-Hayat’ Maglaj. Particular emphasis is placed on the description of the technological process of wastewater treatment at the ‘Natron-Hayat’ Maglaj factory which is represented in the paper by a technological scheme and represents one of the more complex systems for wastewater treatment. In the experimental part, the results of the efficiency of the wastewater treatment system at the ‘Natron-Hayat’ Maglaj factory were given. It can be said that the basic raw materials for paper production are cellulose fibers and water. The role that water has in the cellulose and paper industry as the solvent, agent for cooking and washing of the produced pulp, indicates the presence of water in almost all stages of cellulose fiber production (Žarković et al., 2004). In accordance with the principles of sustainable development, cellulose and paper industry must face strict regulations on the protection of the environment which includes rationalization of raw material consumption, water, energy and chemicals, with ‘Natron-Hayat’ Maglaj are subjected to the purification before discharging into surface water recipient. The wastewaters from ‘Natron-Hayat’ Maglaj factory are discharged into river Bosna.
