Business process improvement of the wastewater treatment: Reducing the risk of environmental pollution

The Republic of Serbia is in the group of European countries, which have evident problems regarding the wastewater treatment. The main goal of the entire research is to point out the future of the process organization, as well as the correlation between the conduction of a concept of business processes and achieved performances management, based on a specific example of wastewater treatment. For the process of wastewater treatment, this paper will represent a "as-IS" model that was applied in the conditions of functional organizational structure, and a "to-BE" model, which was applied within the process orientation. For both of the models a review of the achieved parameters will be given, obtained by the application of the mentioned models. The given parameters indicate the presence of pollutants in wastewater after the conducted treatment process, with a description on how it reflected on the risk of environmental pollution. The innovated model of wastewater treatment achieves significantly better results, which is of great importance for environmental protection. Concrete evidence of the increase of chemical oxygen demand (COD), biological oxygen demand (BOD), total nitrogen (TN), total phosphorus (TP), total suspended solids (TSS) removal with the use of these models is shown in this paper.
