Cadagua Is Participating in the LifeSto3re Conference on Trends and Innovation in Anaerobic Digestion and Sludge Management


Cadagua participated in the LifeSto3re conference at the Centro de Edafología y Biología Aplicada del Segura, part of the Consejo Superior de Investigaciones Científicas (CEBAS-CSIC) in Murcia, where it has displayed the results of their experience in sterilizing dehydrated sludge by mixing it with lime to achieve the objectives of Article 4 of Directive 86/278/EEC. This European directive addresses protecting soil and using sewage sludge in agriculture.

Representatives from the different entities that make up the LifeSto3re initiative, including Cadagua, came together to analyze the latest trends and innovations related to anaerobic digestion of sludge and slurry, as well as managing sludge produced in small and medium-sized wastewater treatment plants.

At the conference, Cadagua gave a presentation entitled “System for dosage and mixing lime in dehydrated sludge for sterilization,” a technique that the company designed and built and that has been in operation since 2017 in the sludge line at the Fuente Alamo treatment plant for ESAMUR (Entidad de Saneamiento y Depuración de aguas residuales de la Región de Murcia).

The European research project LIFE STO3RE, launched in September 2015, has done pilot testing on joint management of sewage sludge and slurry at the Totana treatment plant in Murcia. By combining different technologies that integrate biological and physicochemical processes, they have managed to eliminate organic microcontaminants and pathogens present in sludge and slurry, simultaneously obtaining reusable biogas as an energy source, as well as nitrogen, potassium, and phosphorus for agricultural use in the area.
