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 ... -
Estudi de la recuperació de fosfats d’aigües residuals amb zeolites sintètiques
(Universitat Politècnica de Catalunya, 2015-06)
Master thesis (pre-Bologna period)
Restricted access - author's decisionEn aquest projecte final de carrera s’estudia la recuperació de fosfats d’aigües residuals mitjançant l’adsorció en zeolites sintètiques i cendres volants de centrals tèrmiques de carbó. Es fan servir dues cendres volants ... -

Evaluation of sorbents based on hydrated metal oxides for phosphate removal from industrial and urban effluents
(Universitat Politècnica de Catalunya, 2015-10)
Master thesis
Open AccessS’han estudiat inicialment 8 adsorbents per a la eliminació de fosfat i la seva posterior recuperació de les aigües residuals. Els sòlids JLC triturat, el Clinker OPC triturat i granulat, la Purolite MZ, α-MnO2, ω-MnO2, ... -
Integration of powdered Ca-activated zeolites in a hybrid sorption-membrane ultrafiltration process for phosphate recovery
(2016-05-04)
Article
Open AccessThe feasibility of continuous phosphate recovery, by adsorption on powdered Ca-activated zeolite (PAZ), was assessed in a hybrid sorption membrane ultrafiltration (UF) system. The objective was to explore the influence of ... -
Phosphate recovery by synthetic zeolite and fly-ash: sorption characterization and performance assessment in hybrid sorption-ultrafiltration pilot plant
(Universitat Politècnica de Catalunya, 2015-09)
Master thesis (pre-Bologna period)
Open AccessPhosphorus is a limited global resource; current studies have to be focused mainly on its recovery rather than its disposal. Thereby, the operational lifespan of this resource would be extended and in turn the phosphorus ... -
Phosphate recovery from aqueous solution by K-zeolite synthesized from fly ash for subsequent valorisation as slow release fertilizer
(Elsevier, 2020-08-20)
Article
Restricted access - publisher's policyThe sorption of phosphate by K-zeolites synthesized from fly ash (FA) by hydrothermal conversion is investigated in this study. The aim is the synthesis of Ca bearing K-zeolites to recover phosphate from urban and industrial ... -
Phosphate recovery using calcium zeolite in ultrafiltration pilot plant
(Universitat Politècnica de Catalunya, 2015-10)
Bachelor thesis
Open AccessOne of the most important ecological problems is the eutrophication, this process consist in the uncontrolled growing of algae and phytoplankton, which can destroy entire aquatic ecosystems. The reason of this process ... -
Powdered Ca-activated zeolite for phosphate removal from treated waste-water
(2016-01-01)
Article
Open AccessBackground: A powdered zeolitic material synthesised from fly ash (FA) (NaP1-FA) and its calcium modified form (CaP1-NA) were studied as sorbent materials for the recovery of phosphate from treated waste-water effluents. ... -
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 ... -
Simulación de la implantación de diferentes tecnologías de recuperación de fósforo en una EDAR
(Universitat Politècnica de Catalunya, 2015-10)
Master thesis (pre-Bologna period)
Open AccessLa roca fosfática a partir de la cual se obtiene el fósforo es un recurso esencial, estratégico y limitado que se encuentra en vías de agotamiento (estimaciones en 200 años con pérdidas de competitividad en 50). Por otra ... -
The recycling effect in the nitrification-denitrification process in vertical flow constructed wetlands
(Universitat Politècnica de Catalunya, 2003-07)
Minor thesis
Open AccessUncontrolled discharge of nutrient rich wastewater to the environment is a common source of pollution and it is partly responsible for the eutrophication of surface water, as well as degradation of the quality of groundwater. ...
