Article
Open AccessIn recent years, much attention has been directed towards municipal waste management since these residues has become a global challenge with increasing public health, environmental, social, and economic costs. Therefore, ... -
Estudio de la biosorción multimetálica con raspo de uva mediante técnicas voltamperométricas
(Universitat Politècnica de Catalunya, 2012-06)
Master thesis (pre-Bologna period)
Open AccessEl marco legal relativo a la cantidad de metales pesados permitidos en los vertidos de agua se encuentra, desde hace algunos años, en un continuo proceso de redefinición. Por ello, se hace necesario investigar el desarrollo ... -
Nutrient recovery and valorisation from pig slurry liquid fraction with membrane technologies
(Elsevier, 2023-05)
Article
Open AccessLivestock slurry has been reported to be a potential secondary raw material as it contains macronutrients -nitrogen, phosphorus and potassium-, which could be valorised as high-quality fertilizers if proper separation and ... -
Nutrient recovery from waste water treatment plant by sorption processes : technical and economic analysis
(Universitat Politècnica de Catalunya, 2018-11-29)
Doctoral thesis
Open AccessIn the last years has been performed a huge number of research related to nutrients (mainly N and P) recovery from waste water in order to promote their reuse and also to avoid eutrophication. Recovering nutrient from waste ... -

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 ... -
Recovery of ammonium by powder synthetic zeolites from wastewater effluents: optimization of the regeneration step
(2017-10-01)
Article
Open AccessNitrogen recovery and valorization is gaining interest due to the current need for nitrogen removal, so it is of great interest that ammonium-selective sorbents be evaluated. In this study, a zeolitic material synthesized ... -
Simultaneous recovery of ammonium and phosphate from simulated treated wastewater effluents by activated calcium and magnesium zeolites
(2017-01-01)
Article
Open AccessBACKGROUND In this study a sodium zeolite synthesized from coal fly ash (NaP1-NA) was modified to calcium and magnesium forms (Ze-Ca, Ze-Mg) as sorbent materials for simultaneous recovery of ammonium and phosphate from ...
