Caracterización de la adsorcion de amonio y fosfato mediante zeolitas sintéticas modificadas
(Universitat Politècnica de Catalunya, 2015-04)
Master thesis (pre-Bologna period)
Restricted access - author's decisionEn el contexto legal actual se exige una eliminación del fósforo y nitrógeno casi completa en las aguas residuales. Por otro lado, conseguir recuperar estos nutrientes conllevaría beneficios tanto económicos como ecológicos ... -
Characterization of ammonium and phosphate adsorption by synthetic zeolite
(Universitat Politècnica de Catalunya, 2015-06)
Master thesis (pre-Bologna period)
Open AccessThe excess of nitrogen and phosphorus in the wastewater has caused crucial distortion in the nature such as eutrophication of water basins, disturbed the ecological balance and spoiled the water quality. Moreover, continuing ... -

Evaluation of natural zeolite for Ammonium and Phosphorus removal from tertiary treatment in urban wastewater plants
(Universitat Politècnica de Catalunya, 2014-06)
Master thesis (pre-Bologna period)
Restricted access - author's decisionIn the present work was evaluated the capacity of natural zeolite for ammonium and phosphorus removal and recovery from residual effluents in tertiary treatments of urban wastewater plants. Two different natural zeolites ... -
Modification of a natural zeolite with Fe(III) for simultaneous phosphate and ammonium removal from aqueous solutions
(2016-06-01)
Article
Open AccessBACKGROUND: The incorporation of Fe(III) was performed in a natural clinoptilolite (Z-N) for simultaneous phosphate and ammonium removal. RESULTS: The existence of hydroxyl groups (congruent to Fe-OH) in the iron zeolite ... -
Recovery of ammonium and phosphate from treated urban wastewater by using potassium clinoptilolite impregnated hydrated metal oxides as N-P-K fertilizer
(2016-09-01)
Article
Open AccessA natural clinoptilolite in its potassium form (KNC) was modified by impregnation of hydrated metal oxides (HMO) of aluminium (III) (KAlC), iron (III) (KFeC) and manganese (IV) (KMnC) for the simultaneous ammonium and ... -
Simultaneous ammonium and phosphate removal by metal inorganic salt modification of natural zeolite
(Universitat Politècnica de Catalunya, 2015-01)
Bachelor thesis
Open AccessNutrients discharge into receiving waters can cause an environmental problem capable of deathly altering ecosystems. Natural zeolites are low cost resources with ion exchange capacity that have been widely studied. This ... -
Trace ammonium removal by liquid-liquid membrane contactors as water polishing step of water electrolysis for hydrogen production from a wastewater treatment plant effluent
(2016-01-01)
Article
Open Access© 2016 Society of Chemical Industry. BACKGROUND: This work evaluates hollow fiber liquid-liquid membrane contactors (HFMC) as a polishing step for the removal of low levels of ammonium from water purified by (or being ... -
Validation of zeolites to maximize ammonium and phosphate removal from anaerobic digestate by combination of zeolites in Ca and Na forms
(Universitat Politècnica de Catalunya, 2016-04)
Master thesis (pre-Bologna period)
Open AccessAmmonium and phosphate are fundamental nutrients for human life, but their excess in water can lead to eutrophication, an uncontrolled growth of biomass with a consequent deficit of oxygen (hypoxia) that can be really ... -
Valorization of ammonium from urban waste waters as liquid fertilizers by integration of liquid-liquid membrane contactors and electrodialysis
(2018)
