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 ... -
Avaluació de l’ús de graves de demolició com a substrat en aiguamoll artificial. Seguiment dels fluxos hídrics en el sistema a escala de planta pilot.
(Universitat Politècnica de Catalunya, 2016-10-20)
Bachelor thesis
Open Access
Covenantee: IRTAThe industrial revolution of the 19th century, the low cost of fossil energies, and the exponential increase of the world population has resulted in a greater and greater consumption of non-renewable raw materials; also ... -
