Application of nanoparticules of zero valent iron for nitrate removal from groundwater
(Universitat Politècnica de Catalunya, 2020-07-13)
Master thesis
Open AccessThis study is a state-of-art of nitrate removal using nanoscale zero valent iron in groundwater. In this paper, the options to remediate groundwater contamination are reviewed : biological denitrification by heterotrophs ... -
Atenuació de la contaminació per nitrats en aigua subterrània
(Universitat Politècnica de Catalunya, 2012-12)
Master thesis
Open Access[ANGLÈS] The present work aims to study both natural and induced nitrate attenuation in two locations in Catalonia. One of the study sites is located in the central part of Catalonia (Fonollosa) and the other is located ... -
Avaluació de nanopartícules (nZVI) de Fe en experiments en batch per a l’eliminació de nitrats d’aigües contaminades
(Universitat Politècnica de Catalunya, 2020-09-28)
Bachelor thesis
Open AccessLes aigües subterrànies poden contenir grans nivells de nitrats dissolts. Aquests nivells, poden ser més preocupants quan són provinents de l’agricultura i ramaderia intensiva ja que els nitrats poden ser absorbits per ... -
Avaluació de nanopartícules de ferro (nZVI) en experiments en columes per a l'eliminació de nitrats i pesticides en aigües contaminades
(Universitat Politècnica de Catalunya, 2021-01-29)
Bachelor thesis
Open AccessAquest TFG estudia la descontaminació d’aqüífers que contenen nitrat i pesticides. Els dos tipus de descontaminacions que s’estudien són la reducció del nitrat per mètodes biològics i per mètodes químics utilitzant ... -
