Corrosion in regenerated water distribution systems is a problem that directly affects the integrity of pipes, equipment and fittings, compromising service quality. In order to address this issue, CATABB has launched the COAGTEST-EDAR project, a four-month research initiative aimed at studying the coagulation-flocculation process and assessing water corrosivity in the treatment of Galindo WWTP.

The project will be based on comparative laboratory testing to analyse different treatment strategies and their impact on the parameters that determine water corrosivity. The results will enable the development of technical recommendations to optimise the coagulation-flocculation process, improve treatment efficiency and, fundamentally, mitigate the corrosion phenomena detected in the network.
