Optimization of industrial water networks. Development of generic design tools and application in a real industrial site

Abstract : The application of sustainable water management is vital for all industrial sectors, especially the food industry, one of the most water-consuming sectors. It can be managed by optimizing water reuse, regeneration, and recycling to optimize the production costs and reduce the environmental impacts. Using classical mass integration methods can help to reduce water consumption and wastewater production. Implementing these methods in the food sector faces various challenges, such as the lack of water and wastewater volume in different operations and the data related to pollutant indicators. As a variation of energy pinch, water pinch analysis is a comprehensive and systematic approach that tries to minimize water consummation and wastewater production. This classic method is suitable for mono-contaminant systems. However, most industrial systems are complex and involve multiple contaminants, especially in the food sector. The classic methods are not able to deal with these kinds of problems. Using numerical optimization tools by inspiring water pinch logic is a suitable approach to handling real and complex water networks.Two numerical tools based on the logic of water pinch analysis are developed. The first tool is based on a manual optimization approach assisted by numerical algorithms. The second tool is based on constrained multi-objective optimization. These two tools are developed to handle real and complex industrial water systems that contain multiple contaminants. The designed approaches lead to target the minimum freshwater by using the maximum possibility of reuse. A French edible oil company has been selected as the real industrial application of the developed tools.
