En este proyecto se pretende evaluar los procesos hidrotérmicos (hidrólisis térmica y oxidación húmeda) como métodos de revaloración química de los lodos de estaciones depuradoras de aguas residuales urbanas (EDAR) , como primer paso para convertir a éstos en un recurso renovable de materias primas (proteína, estruvita, ácidos orgánicos...) para otros sectores industriales (piensos, fertilizantes, química de síntesis...). _x000D_ _x000D_ Los aspectos originales que la tecnología propuesta presenta respecto a otras de gestión de lodos (digestión anaerobia, incineración, pirólisis, gasificación... son: i) Se consigue simultáneamente la higienización del lodo, un residuo sólido estabilizado que puede ser empleado como enmienda de suelos y un hidrolizado a partir del cual se obtienen distintas materias primas para otros sectores. ii) las emisiones gaseosas se minimizan y apenas requieren de post-tratamiento. iii) la parte del hidrolizado no recuperada es fácilmente biodegradable y con una menor carga nitrogenada.

This project aims to evaluate hydrothermal processes (thermal hydrolysis and wet oxidation) as methods of chemical reassessment of sludge from urban wastewater treatment plants (WWTPs) , as a first step to convert them into a renewable resource of raw materials (protein, struvite, organic acids...) for other industrial sectors (feed, fertilizers, synthesis chemistry...). _x000D_ _x000D_ The original aspects that the proposed technology presents with respect to other sludge management (anaerobic digestion, incineration, pyrolysis, gasification...) are: i) The sanitation of the sludge is achieved simultaneously, a stabilized solid residue that can be used as soil amendment and a hydrolysate from which different raw materials are obtained for other sectors. ii) Gaseous emissions are minimized and hardly require post-processing. iii) The part of the hydrolysate not recovered is easily biodegradable and with a lower nitrogen load.
