Fram till ganska nyligen var man tvungen att transportera varje droppe vatten till stationen med f\u00f6rs\u00f6rjningsfartyg. Idag finns det utrustning d\u00e4r som \u00e5tervinner avloppsvatten och urin fr\u00e5n astronauterna till dricksvatten! Denna enast\u00e5ende teknik anv\u00e4nds nu f\u00f6r att rena vatten som levereras till skolelever i Marocko.<\/p>\n<\/div>\n<p>ESA har i \u00f6ver 20 \u00e5r arbetat med att utveckla ett effektivt slutet livsuppeh\u00e5llande system som kan behandla avfall och f\u00f6rse astronauterna med f\u00e4rskt syre, mat och vatten. Ett framsteg har varit utvecklingen av extremt tunna membran \u2013 speciella filter med porer (h\u00e5l) som \u00e4r s\u00e5 sm\u00e5 att de kan h\u00e5lla tillbaka o\u00f6nskade f\u00f6roreningar, s\u00e5som nitrat.<\/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>Vattenreningsanl\u00e4ggning<\/figcaption><\/figure>\n<p>I den snabbt v\u00e4xande marockanska staden Sidi Ta\u00efbi \u00e4r grundvattnet s\u00e5 rikt p\u00e5 nitrater och g\u00f6dningsmedel att det inte \u00e4r l\u00e4mpligt som dricksvatten. Men med utg\u00e5ngspunkt i ESA:s membranteknik har franska och tyska f\u00f6retag g\u00e5tt samman f\u00f6r att skapa en vattenreningsanl\u00e4ggning f\u00f6r den lokala gymnasieskolan som drivs med ren energi \u2013 solpaneler och vindkraft.<\/p>\n<p>Tekniken har redan visat sitt v\u00e4rde p\u00e5 andra sidan jordklotet, i Antarktis. Den isomg\u00e4rdade forskningsbasen Concordia anv\u00e4nder ett vattenfiltreringssystem f\u00f6r att \u00e5tervinna avloppsvatten fr\u00e5n duschar, tv\u00e4ttmaskiner och diskmaskiner. Men medan endast 16 personer bor p\u00e5 Concordia kommer den nya vattenreningsanl\u00e4ggningen i Marocko att f\u00f6rs\u00f6rja 1 200 studenter. \u00d6verskottsenergi och vatten som genereras under skolloven kommer att delas med lokalbefolkningen. Om membrantekniken fungerar v\u00e4l i Sidi Ta\u00efbi kommer en betydligt st\u00f6rre anl\u00e4ggning att byggas f\u00f6r att f\u00f6rse resten av stadens befolkning med rent vatten.<\/p>","protected":false},"excerpt":{"rendered":"<p>The International Space Station (ISS) is one of the driest places inhabited by humans.
