The exponential increase of the atmospheric concentration of green-house gases due to human
activities is responsible for the acceleration of global warming and climate change. Recently,
scientific studies have pointed at wastewater treatment systems as relevant sources of fugitive
green-house gases (GHGs) such as nitrous oxide (N2O) and methane (CH4). Nitric oxide (NO) can also
be emitted during wastewater treatment, and it is a potent ozone-depleting compound and a
precursor of N2O. Due to the high global warming potential of N2O and CH4, emission of these gases
(even at low levels) may be relevant and increase severely the overall carbon footprint of a
wastewater treatment system.
L’acceleracio en l’escalfament global i el canvi climatic son consequencia de l’increment
exponencial de la concentracio de gasos d’efecte hivernacle en l’atmosfera degut, en part, a
l’activitat humana. Estudis cientifics publicats recentment apunten a alguns sistemes de tractament
d’aigues residuals com a fonts rellevants de gasos d’efecte hivernacle com l’oxid nitros (N2O) i el
meta (CH4). A mes, l’oxic nitric (NO), un potent destructor de la capa d’ozo a mes de ser un precursor
del N2O, tambe pot ser emes durant el tractament d’aigues residuals. Degut a l’alt potencial
d’escalfament atmosferic del N2O i el CH4, l’emissio d’aquests gasos (inclus a baixes concentracions)
pot ser rellevant, incrementant de forma significativa la petjada ecologica dels sistemes de
tractament d’aigues residuals.
