“…The development of methodologies for the optimization of water use in pulp and papermaking processes represents an effective mechanism for environmental management and water sustainability, whose consumption can reach 700,000 L of water (MIERZWA;HESPANHOL, 2005). An important tool of Process Engineering is the Wastewater Sources Diagram (WWSD) method (DELGADO et al, 2009;MOREIRA et al, 2015), based on the algorithmic-heuristic procedure called the Water Sources Diagram (WSD) (CALIXTO et al, 2020;GOMES et al, 2007;2013). This type of approach uses the concept of transfer of contaminant species from a process stream to an aqueous stream, in an operation that uses water as a mass transfer agent.…”

The increase in the costs of water and wastewater treatment makes it relevant to develop tools that allow the efficient use of water in the industry, aiming at reduce costs and respecting the disposal limits imposed by the legislation. Thus, the objective of this work is to apply an integrated methodology for the synthesis and analysis of water networks and industrial wastewaters, combining the Wastewater Sources Diagram (WWSD) method with the results of the Water Sources Diagram (WSD) to the data representative of the pulp and paper industry. A case study considering the relevant contaminants present in the wastewaters from this process was carried out. The wastewater treatment network generated with the WWSD reduced the need for wastewater treatment by 35.20%, allowing lower costs and environmental impacts.

“…Those improvements were also motivated by the feedback given by several kinds of companies where WSD was employed. WSD presented good results in regeneration processes [11,12], integrating water-thermal networks [13], in regeneration equipment [14] in oil refineries [4,7,15], in batch processes [16], pulp and paper facilities [8,17,18], in textile industry [19] and in a thermoelectric plant [20].…”

Water Sources Diagram (WSD) has proved to be one of the most efficient methods to reduce industrial freshwater consumption and to provide a minimum amount of wastewater to be treated. Different types of industry have been benefited from the use of this technique, which resulted in great savings in the design of the effluent treatment systems. Among the successful case studies, we mention herein applications in systems with wastewater treatment, thermal and water plants' integration, oil refineries, petrochemicals, batch processes, pulp and paper plants, and textile plants. The degree of WSD maturity motivated researchers to not only improve WSD algorithms, but also extend the concept of the Sources Diagram to Source/Sink types of process. This paper presents a background of WSD progress as well as insights into future perspectives using the Sources Diagrams' concept.
