Ammonia removal from water by liquid-liquid membrane contactor under closed loop regime
(2012)
Conference report
Restricted access - publisher's policyAmmonia separation from water by a membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside a hydrophobic ... -
Ammonium removal by liquid–liquid membrane contactors in water purification process for hydrogen production
(2015-01-01)
Article
Open Access© 2014 Balaban Desalination Publications. All rights reserved. In this work, a liquid–liquid membrane contactor (LLMC) was evaluated to remove ammonia traces from water used for hydrogen production by electrolysis. Three ... -
Asymmetric electroosmotic pumping across porous media sandwiched with perforated ion-exchange membranes
(2017-07-01)
Article
Open AccessTo have non-zero net flow in AC electroosmotic pumps, the electroosmosis (EO) has to be non-linear and asymmetric. This can be achieved due to ionic concentration polarization. This is known to occur close to micro-/nano ... -
Characterization and modelling of micro and nanofluidic systems
(Universitat Politècnica de Catalunya, 2015-03-13)
Doctoral thesis
Open AccessLab-on-a-chip arrangements are ever more frequently used for the miniaturization of chemical and biochemical analysis. In these arrangements, all the manipulations of analyte transport, separation, mixing with reactants ... -
Electrokinetics in undeveloped flows
(2013-11)
Article
Restricted access - publisher's policyFor the correct interpretation of results of tangential electrokinetic measurements with porous materials, in particular, composite/asymmetric membranes on porous supports, it is necessary to have the data available for ... -
Evaluating the integration of nanofiltration membranes in advanced water reclamation schemes using synthetic solutions: From phosphorous removal to phosphorous circularity
(2022-06)
Article
Restricted access - publisher's policyThe more stringent regulations related to the reduction of residual phosphorous concentration in treated wastewater and the consideration of phosphorous as a critical raw material are boosting new technologies towards its ... -
Experimental and theoretical study of nanofiltration of weak electrolytes: SO4 2–/HSO4 –/H+ system
(2018-03-15)
Article
Open Access© 2018 Elsevier B.V. Over recent years, nanofiltration (NF) has been considered as an effective way to improve processing steps in metallurgical and hydrometallurgy applications dealing with mixtures of metal ions in ... -
Hydrodynamic dispersion in long microchannels under conditions of electroosmotic circulation: II. Electrolytes
(2016-03-19)
Article
Open AccessThis work describes the steady-state transport of an electrolyte due to a stationary concentration difference in straight long channels under conditions of electroosmotic circulation. The electroosmotic flow is induced due ... -
Recovery of ammonia from domestic wastewater effluents as liquid fertilizers by integration of natural zeolites and hollow fibre membrane contactors
(2017-04-15)
Article
Open AccessThe integration of up-concentration processes to increase the efficiency of primary sedimentation, as a solution to achieve energy neutral wastewater treatment plants, requires further post-treatment due to the missing ... -
Rejection of ammonium and nitrate from sodium chloride solutions by nanofiltration: Effect of dominant-salt concentration on the trace-ion rejection
(Elsevier, 2016-06-04)
Article
Open AccessIn this work, the rejection of two ions associated with fertilizer pollution of ground water (NH4+ and NO3-) by a polyamide nanofiltration (NF270) membrane was studied. Sodium chloride was selected as the dominant salt and ... -

Open AccessIn this work, the rejection of two ions associated with fertilizer pollution of ground water (NH4and NO3) by a polyamide nanofiltration (NF270) membrane was studied. Sodium chloride was selected as the dominant salt and ... -
Separation of ions using polyelectrolyte-modified nanoporous track-etched membranes
(2013)
Article
Restricted access - publisher's policySelective ion exclusion from charged nanopores in track-etched membranes allows separation of ions with different charges or mobilities. This study examines pressure-driven transport of dissolved ions through track-etched ... -
Simultaneous ammonium and phosphate recovery and stabilization from urban sewage sludge anaerobic digestates using reactive sorbents
(Elsevier, 2018-07-15)
Article
Open AccessThe use of low-cost inorganic sorbents as a new sustainable strategy to enhance the valorization of nutrients (N-P-K), from the urban water cycle (e.g., side streams from sewage sludge anaerobic digestion), in agriculture ... -
Solution-diffusion–electro-migration model and its uses for analysis of nanofiltration, pressure-retarded osmosis and forward osmosis in multi-ionic solutions

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 ... -
Valorization of ammonia concentrates from treated urban wastewater using liquid–liquid membrane contactors
(2016-05-21)
Article
Open AccessThe removal of ammonium from tertiary effluents by zeolites generates basic ammonia concentrates (up to 1–3 gNH3/L in 1–2 g NaOH/L). This study evaluates the use of hollow fibre liquid–liquid membrane contactors (HFMCs) ...
