Control4Reuse aims at researching and developing technologies for managing treated water resources. The optimization of water treatment and reclamation systems in an integrated manner is foreseen as a sustainable solution to improve the reuse of this valuable water resource. The emphasis of the project is on the reuse of wastewater in specific agricultural and industrial sectors. From a technological viewpoint, the scope of the project is casted within a system monitoring and control framework, with specific activities ranging from the supervision and integration of sensor information/data, mathematical modelling of the processes and the design of advanced control strategies. The very different scenarios and climates offered by the three countries (Brazil/Ceará, France and Sweden) participating in the project consortium, will allow the definition of a wide spectrum of solutions for water reuse.
