Adsorption and recovery of phosphate from aqueous solution by the construction and demolition wastes sludge and its potential use as phosphate-based fertiliser
(Elsevier, 2020-02-01)
Article
Open AccessThis study aimed to investigate phosphate removal from aqueous effluents by an inorganic sludge from the inert part of construction and demolition wastes (CSW) as adsorbent. It is also discussed the application of the ... -
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 ... -
Determinación de la máxima capacidad de adsorción de la tierra de arriera en la eliminación de fosfatos en soluciones acuosas
(2013-12)
Article
Open AccessLos materiales existentes en el trópico como es la tierra de arriera pueden ser usados como una herramienta de biorremediación en procesos de purificación y descontaminación de aguas residuales contaminadas. El objetivo ... -
Estudi de la precipitació de fosfat i l’adsorció d’amoni a l’efluent de la línea de fangs
(Universitat Politècnica de Catalunya, 2016-10-03)
Bachelor thesis
Open AccessEl nitrogen i el fòsfor són dos elements essencials per a la supervivència dels éssers vius. Actualment, el fòsfor és un recurs limitat degut a la sobreexplotació de roca fosfàtica de qualitat per a la producció de ... -
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 ... -

Estudio y caracterización de la magnetita para su aplicación a la fertilización de suelos agrícolas
(Universitat Politècnica de Catalunya, 2013-09)
Master thesis (pre-Bologna period)
Open AccessEn los últimos años hay una preocupación creciente respecto al impacto de las actividades agrícolas en el medio ambiente. Algunos de los principales problemas asociados al uso de fertilizantes son la eutrofización (aumento ... -
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, ... -
Fly ash as reactive sorbent for phosphate removal from treated waste water as a potential slow release fertilizer
(2017-02-01)
Article
Open AccessThere is interest in recovering phosphate (P(V)) from secondary sources, such as waste water streams for potential use as fertilizers reducing the environmental impacts of P(V) discharges and providing alternative phosphorus ... -
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 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 ... -
Phosphate removal from aqueous solutions using a hybrid fibrous exchanger containing hydrated ferric oxide nanoparticles
(2016)
Article
Open AccessThis study presents the evaluation of a fibrous ion exchanger impregnated with nanoparticles of hydrated ferric oxide (HFO) as a selective sorbent for phosphate. The hybrid impregnated anion exchanger (FIBAN-As) combines ... -
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. ...
