Constructed wetland microbial fuel cells : electricity generation, treatment efficiency improvement, COD bioindication and clogging assessment
(Universitat Politècnica de Catalunya, 2017-11-10)
Doctoral thesis
Open AccessHorizontal Subsurface Flow Constructed Wetlands (HSSF CWs) are natural wastewater treatment systems showing a marked redox gradient between the surface of the system and the bottom zone of the treatment bed. Therefore, ... -
Effect of primary treatment and organic loading on methane emissions from horizontal subsurface flow constructed wetlands treating urban wastewater
(2015-07)
Article
Open AccessMethane is emitted in horizontal subsurface flow constructed wetlands (HSSF CWs) during wastewater treatment. The objective of this work was to determine the influence of primary treatment and organic loading rate on methane ... -
Electrochemical characterization of Geobacter lovleyi identifies limitations of microbial fuel cell performance in constructed wetlands
(2017-04)
Article
Open AccessMicrobial Fuel Cells implemented in Constructed Wetlands (CW-MFCs) show limited performance. Geobacter Lovleyi has been demonstrated to be one of the predominant bacterial species in active CW-MFCs. The aim of this study ... -
Emissió de gasos d'efecte hivernacle en aiguamolls construïts: adaptació del mètode de la cambra estàtica i mesura en funció del règim hidràulic i de l’existència de plantes
(Universitat Politècnica de Catalunya, 2012-01-27)
Minor thesis
Open AccessCatalà: Els aiguamolls construïts són sistemes de tractament d’aigua que, simulant els aiguamolls existents a la natura, estan considerats com un dels sistemes de depuració més eficients. En tant que alternativa als sistemes ... -
Improving domestic wastewater treatment efficiency with constructed wetland microbial fuel cells: influence of anode material and external resistance
(Elsevier, 2018-08)
Article
Open AccessFor the past few years, there has been an increasing interest in the operation of constructed wetlands as microbial fuel cells (CW-MFCs) for both the improvement of wastewater treatment efficiency and the production of ... -
Improving the reliability of closed chamber methodologies for methane emissions measurement in treatment wetlands
(2013)
Conference report
Restricted access - publisher's policyNon-homogeneous mixing of methane (NHM) within closed chambers was studied under laboratory conditions. The experimental set up consisted of a PVC vented chamber of 5.3 litres of effective volume implemented with a ... -

Restricted access - publisher's policyNon-homogeneous mixing of methane (NHM) within closed chambers was studied under laboratory conditions. The experimental set-up consisted of a PVC vented chamber of 5.3 litres of effective volume fitted with a power-adjustable ... -
Life cycle assessment of constructed wetland systems for wastewater treatment coupled with microbial fuel cells
(2017-04)
Article
Open AccessThe aim of this study was to assess the environmental impact of microbial fuel cells (MFCs) implemented in constructed wetlands (CWs). To this aim a life cycle assessment (LCA) was carried out comparing three scenarios: ... -
Long-term assessment of best cathode position to maximise microbial fuel cell performance in horizontal subsurface flow constructed wetlands
(Elsevier, 2016-09)
Article
Open AccessThe cathode of microbial fuel cells (MFCs) implemented in constructed wetlands (CWs) is generally set in close contact with water surface to provide a rich oxygen environment. However, water level variations caused by ... -
MFC-based biosensor for domestic wastewater COD assessment in constructed wetlands
(Elsevier, 2019-04)
Article
Open AccessIn the context of natural-based wastewater treatment technologies (such as constructed wetlands - CW) the use of a low-cost, continuous-like biosensor tool for the assessment of operational conditions is of key importance ... -
Microbial activity enhancement in constructed wetlands operated as bioelectrochemical systems
(2022-01)
Article
Open AccessTreatment wetlands (TW) operated as bioelectrochemical systems (BES-TW) provide a higher degree of treatment than conventional TW. Yet, the fundamental processes or mechanisms for the envisaged better performance of BES-TW ... -
Microbial fuel cells for clogging assessment in constructed wetlands
(2016-11)
Article
Open AccessClogging in HSSF CW may result in a reduction of system's life-span or treatment efficiency. Current available techniques to assess the degree of clogging in HSSF CW are time consuming and cannot be applied on a continuous ... -
