Open AccessConstructed wetlands are a popular form of waste-water treatment that have proliferated across Europe and the rest of the world in recent years as an environmentally conscious form of waste water treatment. The ability to ... -
Aplicación de los sistemas bio-electroquímicos en humedales construidos para la mejora del tratamiento de aguas residuales domésticas
(Universitat Politècnica de Catalunya, 2018-06)
Bachelor thesis
Open AccessEls aiguamolls construïts representen una bona alternativa per al tractament de l'aigua residual domèstica. Tanmateix les reaccions de descontaminació són més lentes que en sistemes de tractament convencionals i, per tant, ... -
Application of the gas tracer method for measuring oxygen transfer rates in subsurface flow constructed wetlands
(2010-07)
Article
Restricted access - publisher's policyThe oxygen transfer rate (OTR) has a significant impact on the design, optimal operation and modelling of constructed wetlands treating wastewater. Oxygen consumption is very fast in wetlands and the OTR cannot be determined ... -
Are ciliated protozoa communities affected by macrophyte species, date of sampling and location in horizontal sub-surface flow constructed wetlands?
(2012-06)
Article
Restricted access - publisher's policyThe effects of design and operational factors on the dynamics of ciliated protozoa in constructed wetlands (CWs) treating wastewater remain poorly known, although bacterivory by ciliates could have important implications ... -
Assessing the economic suitability of aeration and the influence of bed heating on constructed wetlands treatment efficiency and life-span
(2015-10)
Article
Open AccessConstructed wetlands including aeration and heating were studied to improve treatment efficiency and prevent clogging. The experiments were carried out in a pilot plant (0.4 m(2)) treating urban wastewater with an organic ... -
Bacterial transformation and biodegradation processes simulation in horizontal subsurface flow constructed wetlands using CWM1-RETRASO
(2011-01-01)
Article
Restricted access - publisher's policyThe performance and reliability of the CWM1-RETRASO model for simulating processes in horizontal subsurface flow constructed wetlands (HSSF CWs) and the relative contribution of different microbial reactions to organic ... -
Biodegradabilidat aeròbia i anaeròbia de la matèria orgànica acumulada en aiguamolls per depurar aigua
(Universitat Politècnica de Catalunya, 2011-02-17)
Minor thesis
Open AccessEl present treball estudia la topologia dels sòlids acumulats a aiguamolls construïts de flux subsuperficial i la seva potencial biodegradabilitat per via aeròbia i anaeròbia, en una planta pilot que consta de tres línies ... -

Boosting pharmaceutical removal through aeration in constructed wetlands
(2021-06)
Article
Open AccessThis work evaluated the removal efficiency of 13 wastewater-borne pharmaceuticals in a pilot constructed wetland (CW) operated under different aeration strategies (no aeration, intermittent and continuous). Aeration improved ... -
By-pass hídrico : intervención en el polígono industrial "La Ferrería" para la mejora de la gestión del agua a través de intervenciones urbanas
(Universitat Politècnica de Catalunya, 2024-06-26)
Master thesis
Open AccessLos polígonos industriales representan las superficies más impermeables dentro de las tipologías de uso del suelo. En la cuenca del Besós estos han ido sustituyendo los espacios de ribera reduciendo así las zonas de recarga ... -
Can high rate algal ponds be used as post-treatment of UASB reactors to remove micropollutants?
(2020-06)
Article
Open AccessThe present study evaluated the removal capacity of a UASB-HRAP treatment system, combining anaerobic and microalgae-based, aerobic treatment, for eleven organic micropollutants present in raw sewage, including pharmaceuticals, ... -
Carbon footprint of constructed wetlands for winery wastewater treatment
(2020-09)
Article
Open AccessThe aim of this study was to estimate the carbon footprint (CFP) of constructed wetlands for winery wastewater treatment. In particular, a constructed wetland scenario was compared to the previous scenario (third-party ... -
Changes in bacteria composition and efficiency of constructed wetlands under sustained overloads: a modeling experiment
(Elsevier, 2018-01)
Article
Open AccessThe average organic and hydraulic loads that Constructed Wetlands (CWs) receive are key parameters for their adequate long-term functioning. However, over their lifespan they will inevitably be subject to either episodic ... -
Characterization of rice husk and cork as waste materials and its integration in a WETWALL system
(Universitat Politècnica de Catalunya, 2017-06-16)
Master thesis
Restricted access - author's decisionWastewater effluents from soilless crop cultivation contain high loads of nutrients and are poor in organic carbon, what makes its purification with conventional treatment methods challenging and expensive. Constructed ... -
Comparative efficiency of two different constructed wetlands for wastewater treatment of small populations in Mediterranean continental climate
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-06)
Article
Open AccessThe treatment of wastewater from small towns supposes problems of economic efficiency, leading to very high environmental costs in areas with low population density. Constructed wetlands (CW) seems to be the more suitable ... -
