Den Internationale Rumstation (ISS) er et af de t\u00f8rreste steder, hvor mennesker opholder sig. Indtil for ganske nylig m\u00e5tte hver eneste dr\u00e5be vand transporteres til stationen med forsyningsskibe. I dag rummer den udstyr, der genanvender spildevand og urin fra astronauterne til drikkevand! Denne bem\u00e6rkelsesv\u00e6rdige teknologi anvendes nu til at rense vand, der leveres til skoleelever i Marokko.<\/p>\n<\/div>\n

ESA har i over 20 \u00e5r arbejdet p\u00e5 at udvikle et effektivt lukket livsst\u00f8ttesystem, der kan behandle affald og forsyne astronauterne med frisk ilt samt mad og vand. Et af fremskridtene har v\u00e6ret udviklingen af ekstremt tynde membraner \u2013 specielle filtre med porer (huller), der er s\u00e5 sm\u00e5, at de kan tilbageholde u\u00f8nskede forurenende stoffer, s\u00e5som nitrat.<\/p>\n

Vandrensningsanl\u00e6g<\/figcaption><\/figure>\n

I den hurtigt voksende marokkanske by Sidi Ta\u00efbi er grundvandet s\u00e5 rig p\u00e5 nitrater og g\u00f8dning, at det ikke er egnet som drikkevand. Men med udgangspunkt i ESA's membranteknologi har franske og tyske virksomheder indg\u00e5et et samarbejde om at udvikle et vandrensningsanl\u00e6g til den lokale gymnasium, der drives af ren energi \u2013 solceller og vindkraft.<\/p>\n

Teknologien har allerede bevist sit v\u00e6rd p\u00e5 den anden side af kloden i Antarktis. Den isomgivne forskningsstation Concordia bruger et vandfiltreringssystem til at genanvende spildevand fra brusere, vaskemaskiner og opvaskemaskiner. Men mens der kun bor 16 mennesker p\u00e5 Concordia, skal det nye vandrensningsanl\u00e6g i Marokko forsyne 1 200 studerende. Overskydende energi og vand, der genereres i skoleferierne, vil blive delt med lokalbefolkningen. Hvis membranteknologien fungerer godt i Sidi Ta\u00efbi, vil der blive udviklet et langt st\u00f8rre anl\u00e6g, der skal levere rent vand til resten af byens befolkning.<\/p>","protected":false},"excerpt":{"rendered":"
