Treatment of livestock waste products for the fixation of ammoniacal nitrogen (NH4+N) using magnesium by-products
Tratamiento de los purines por fijación del nitrógeno amoniacal (N-NH4+) utilizando subproductos de magnesio
Context
This project aims to resolve the current problems associated with the management and treatment of organic waste products from livestock farming, principally within the pig farming sector. Such problems have arisen from existing limitations regarding the application of nitrogen (N) and phosphorous (P) as fertilisers, due to their negative impact on the contamination of aquifers and agricultural fields. We endeavour to address these issues through the application of a novel, laboratory tested, environmentally sustainable technology that has been patented by the University of Barcelona (ES2332300B1 / WO2010/018260A1).
Objectives
To demonstrate the applicability and viability of a low-cost, continuous process to reduce the level of ammoniacal N (NH3-N) in livestock waste products from the pig farming sector (by 70–90%).
To generate different formulas that will aid replication and transferability.
To obtain different solid precipitates during the recovery of free NH3-N from livestock waste products and assess their potential reuse as slow-release organo-mineral fertilisers.
To demonstrate the technical-economical validity of this new technology across different treatment scenarios.
To minimise soil and water contamination.
Objectives
Demostrar la aplicabilidad y viabilidad de un proceso en continuo de bajo coste para la reducción de la concentración de N-amoniacal (N-NH3) en las deyecciones ganaderas del sector porcino (entre 70-90%)
Realización de diferentes formulaciones, para favorecer su replicabilidad y transferencia.
Obtener diferentes productos sólidos precipitados durante la recuperación del N-NH3 libre, contenido en las deyecciones ganaderas, y su posibilidad de reutilización como fertilizante organomineral de liberación lenta.
Validar técnica-económicamente la nueva tecnología en diferentes escenarios de tratamiento
Minimizar la contaminación de los suelos y aguas.
Activities
the tests carried out at the laboratory and pilot plant scales (500/1000L) lead us to conclude that it is feasible to reduce the concentration of ammoniacal nitrogen contained in pig manure by up to 70-75%. The technical, economic and environmental optimisation that justifies the replicability of the technology developed has therefore been demonstrated.
Activities
En definitiva, los ensayos realizados a escala laboratorio y en planta piloto (500/1.000 L) han permitido concluir que es factible reducir hasta un 70-75 % la concentración de nitrógeno amoniacal contenido en una deyección ganadera del sector porcino. Así pues, queda demostrada la optimización técnico-económica y medioambiental que permite la reproducibilidad de la tecnología desarrollada.
