Jusqu\u2019\u00e0 r\u00e9cemment, chaque goute d\u2019eau devait y \u00eatre achemin\u00e9e par des vaisseaux de ravitaillement. Cette \u00e9poque est r\u00e9volue : l\u2019avant-poste orbital est aujourd\u2019hui \u00e9quip\u00e9 d\u2019un syst\u00e8me permettant de recycler les eaux us\u00e9es et l\u2019urine des astronautes en eau potable. Cette technologie exceptionnelle a \u00e9t\u00e9 choisie pour traiter les eaux souterraines puis\u00e9es par une \u00e9cole marocaine.<\/p>\n<\/div>\n<p>Depuis plus de 20 ans, l\u2019ESA travaille au d\u00e9veloppement d\u2019un syst\u00e8me de support de vie en circuit ferm\u00e9 qui traite les d\u00e9chets, fournit de l\u2019oxyg\u00e8ne, de la nourriture et de l\u2019eau aux astronautes. Ce programme a notamment permis de cr\u00e9er des membranes de nouvelle g\u00e9n\u00e9ration. Ces filtres sp\u00e9ciaux, perc\u00e9s d\u2019une multitude de pores (des trous minuscules), permettent de bloquer les compos\u00e9s ind\u00e9sirables, en particulier les nitrates.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1024\" data-credit=\"Firmus\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2014\/05\/Water_treatment_facility\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2014\/05\/water_treatment_facility\/17893500-2-eng-GB\/Water_treatment_facility.jpg\" alt=\"Water treatment facility\"><figcaption>Station de traitement des eaux<\/figcaption><\/figure>\n<p>Dans la ville marocaine de Sidi Ta\u00efbi, en pleine expansion, les eaux souterraines sont si riches en nitrates et en engrais qu\u2019elles ne sont pas propres \u00e0 la consommation humaine. Cependant, s'appuyant sur la technologie membranaire de l'ESA, des entreprises fran\u00e7aises et allemandes se sont associ\u00e9es pour cr\u00e9er une station de traitement de l'eau destin\u00e9e au lyc\u00e9e local, aliment\u00e9e par des \u00e9nergies propres : panneaux solaires et \u00e9olien.<\/p>\n<p>Cette technologie a d\u00e9j\u00e0 fait ses preuves \u00e0 l\u2019autre bout du monde, en Antarctique. La base de recherche polaire Concordia utilise depuis plusieurs ann\u00e9es un syst\u00e8me de filtration permettant de recycler l\u2019eau utilis\u00e9e pour les douches, ainsi que les machines \u00e0 laver le linge et la vaisselle. La base de Concordia accueille un nombre maximal de 16 personnes, tandis que la nouvelle installation de traitement des eaux au Maroc fournira de l\u2019eau pour 1 200 \u00e9l\u00e8ves. Le surplus d\u2019\u00e9nergie et d\u2019eau g\u00e9n\u00e9r\u00e9 pendant les vacances scolaires sera partag\u00e9 avec la population locale. Si cette technologie de membrane fonctionne correctement \u00e0 Sidi Ta\u00efbi, les installations seront agrandies pour fournir de l\u2019eau potable au reste de la population.<\/p>","protected":false},"excerpt":{"rendered":"<p>The International Space Station (ISS) is one of the driest places inhabited by humans.
