Reuse as low concentration bleach or to clean water softeners are some of the uses that are also being tested
Researchers at the Universidad Politécnica de Cartagena (UPCT) have asked the Hydrographic Confederation of Segura and the General Environment Directorate for approval to build a small reservoir to safely collect brine and the subsequent reopening of the desalination plant Experimental Agro-alimentary Station Tomás Ferro, in order to be able to test new techniques of denitrification of this byproduct and to supply brine to the pilot plants that are studying its reuse in industrial processes.
The closure of the desalination plants of the Campo de Cartagena adopted last year to reduce the arrival of nitrates in the Mar Menor affected the desalination plant of the Finca Tomas Ferro and is blocking research that precisely seeks to treat and reuse the brine generated by these wells To protect the natural environment and improve the sustainability of agriculture in the area.
"Without nitrates, brine would no longer be detrimental to marine ecosystems, but the ideal would be to valorize them and turn them into useful byproducts," explains researcher Juan José Martínez, director of the Chair of Sustainable Agriculture in the Cartagena Field UPCT-COAG -FECOAM.
Other researchers are working on different brine solutions and applications, such as alumni of the Polytechnic who have created a company to reuse it as a low concentration bleach for use as a disinfectant in the agri-food industry;
Or as the company INSAL, which provides for its appreciation in the cleaning of decalcification systems.
Both lines of work were presented Monday in a day of the Chair held in the Ministry of Agriculture.
"It is urgent to unblock the situation of the experimental de-aerators.
We need brine for the research to pass from the laboratory to an industrial scale, "concludes Juan Jose Martinez.
