- Abstract
The water resources management has been an important factor for the sustainability of industrial processes, since there is a growing need for the development of methodologies aimed at the conservation and rational use of water. The objective of this work was to apply the heuristic-algorithmic method called Water Sources Diagram (WSD), which is used to define the target of minimum water consumption, to batch processes. Scenarios with reuse of streams were generated and evaluated with application of the method from the data of water quantity and concentration of contaminants in the operations. Two case studies aiming to show the reduction of water consumption and wastewater generation, and final treatment costs besides investment in storage tanks, were presented. The scenarios showed great promising, achieving reduction up to 45% in water consumption and wastewater generation, and a reduction of around 37% on cost of storage tanks, without the need to allocate regeneration processes. Thus, the WSD method showed to be a relevant and flexible alternative regarding to systemic tools aimed at minimizing the consumption of water in industrial processes, playing an important role within a program of water resources management.
