\u00c0 Cuba, l\u2019eau arrive dans les maisons, contamin\u00e9e par des bact\u00e9ries et des virus. Actuellement, les citoyens bouillent l\u2019eau afin de la st\u00e9riliser. Cependant, le k\u00e9ros\u00e8ne y est limit\u00e9 et l\u2019eau bouillante provoque fr\u00e9quemment des brulures chez les enfants. <\/span><\/span>Existe-il un moyen \u00ab\u00a0accessible\u00a0\u00bb aux cubains, pour fabriquer un filtre \u00e0 UV-C durable, aliment\u00e9 par une source \u00e9lectrique ind\u00e9pendante pouvant st\u00e9riliser l\u2019eau sans la bouillir\u00a0?<\/span><\/span>\u00a0<\/span><\/span><\/p>

La technique de st\u00e9rilisation par UV-C, est une pratique d\u00e9j\u00e0 employ\u00e9e dans des stations d\u2019\u00e9puration de nombreuses villes (telle que Edmonton), dans les h\u00f4pitaux (st\u00e9rilisation de mat\u00e9riel), tout comme dans des associations caritatives comme \u00ab\u00a0Viva con agua\u00a0\u00bb ou \u00ab\u00a0Gelsenwasser\u00a0\u00bb au Nepal. Mais il existe \u00e9galement d'autres moyens comme le \u00ab\u00a0St\u00e9ripen\u00a0\u00bb, ou des \u00ab\u00a0filtres \u00e0 \u00e9tangs\u00a0\u00bb qui traitent les germes pr\u00e9sents dans l\u2019eau. <\/span><\/span>\u00a0<\/span><\/span><\/p>

Ces pratiques fonctionnent toutes de la m\u00eame mani\u00e8re. Les ondes UV-C engendrent un effet germicide sur les bact\u00e9ries et les virus. Celles-ci sont toujours \u00e9mises par des sources artificielles, comme par exemple des lampes halog\u00e8nes UV-C.<\/span><\/span>\u00a0<\/span><\/span>Dans ce projet, l\u2019hypoth\u00e8se serait de filtrer l\u2019eau courante de Cuba, avec un filtre portable et facilement connectable \u00e0 des bouteilles en PVC.<\/span><\/span>\u00a0<\/span><\/span><\/p>

L\u2019objectif premier, est de mettre en place un outil de pratique, pouvant \u00eatre fabriqu\u00e9 par n\u2019importe quelle personne (ayant acc\u00e8s \u00e0 un Fablab). Pour ce faire, nous avons \u00e9tudi\u00e9 le fonctionnement des objets d\u00e9j\u00e0 pr\u00e9sents dans la soci\u00e9t\u00e9 comme cit\u00e9 plus haut, le filtre \u00e0 \u00e9tang. Pour appuyer notre compr\u00e9hension, des recherches scientifiques se sont dirig\u00e9es vers les techniques pratiqu\u00e9es notamment en Allemagne et France.<\/span><\/span>\u00a0<\/span><\/span>Une fois toutes les informations recueillies, l\u2019\u00e9tape suivante fut de r\u00e9pertorier des pi\u00e8ces standards les plus abordables possible, accessibles partout dans le monde et qui peuvent \u00eatre import\u00e9es \u00e0 Cuba.\u00a0<\/span><\/span>\u00a0<\/span><\/span><\/p>

Au stade actuel, nous avons mis en place une hypoth\u00e8se et un outil exp\u00e9rimental, qui r\u00e9pondent aux crit\u00e8res pr\u00e9c\u00e9demment \u00e9voqu\u00e9s. Pour r\u00e9aliser cet outil, plusieurs \u00e9l\u00e9ments sont n\u00e9cessaires comme une lampe halog\u00e8ne UV-C (12V 9W), un tube en quartz (30cm), un anneau d\u2019\u00e9tanch\u00e9it\u00e9 (d-5cm), une douille (g23) adaptable pour la lampe et une batterie combin\u00e9e avec un transformateur de 5V en 12V (voir jusqu\u2019\u00e0 20V). L\u2019ensemble reviendrait \u00e0 un co\u00fbt estim\u00e9 \u00e0 35 <\/span><\/span>\u20ac (hors frais de livraison) <\/span><\/span><\/p>

Notons que pour l\u2019impression en 3D, il faut veiller \u00e0 utiliser du plastique ASA, qui r\u00e9siste aux UV.\u00a0Il est int\u00e9ressant de\u00a0pr\u00e9ciser\u00a0que la lampe UV-C peut s\u2019illuminer 8000 heures et par ce fait, peut\u00a0filtrer en moyenne 720 000 litres d\u2019eau. <\/span><\/span>\u00a0<\/span><\/span><\/p>\",\r\n \"align\": \"top\",\r\n \"row\": -1,\r\n

\u00c0 Cuba, l\u2019eau arrive dans les maisons, contamin\u00e9e par des bact\u00e9ries et des virus. Actuellement, les citoyens bouillent l\u2019eau afin de la st\u00e9riliser. Cependant, le k\u00e9ros\u00e8ne y est limit\u00e9 et l\u2019eau bouillante provoque fr\u00e9quemment des brulures chez les enfants. <\/span><\/span>Existe-il un moyen \u00ab\u00a0accessible\u00a0\u00bb aux cubains, pour fabriquer un filtre \u00e0 UV-C durable, aliment\u00e9 par une source \u00e9lectrique ind\u00e9pendante pouvant st\u00e9riliser l\u2019eau sans la bouillir\u00a0?<\/span><\/span>\u00a0<\/span><\/span><\/p>

La technique de st\u00e9rilisation par UV-C, est une pratique d\u00e9j\u00e0 employ\u00e9e dans des stations d\u2019\u00e9puration de nombreuses villes (telle que Edmonton), dans les h\u00f4pitaux (st\u00e9rilisation de mat\u00e9riel), tout comme dans des associations caritatives comme \u00ab\u00a0Viva con agua\u00a0\u00bb ou \u00ab\u00a0Gelsenwasser\u00a0\u00bb au Nepal. Mais il existe \u00e9galement d'autres moyens comme le \u00ab\u00a0St\u00e9ripen\u00a0\u00bb, ou des \u00ab\u00a0filtres \u00e0 \u00e9tangs\u00a0\u00bb qui traitent les germes pr\u00e9sents dans l\u2019eau. <\/span><\/span>\u00a0<\/span><\/span><\/p>

Ces pratiques fonctionnent toutes de la m\u00eame mani\u00e8re. Les ondes UV-C engendrent un effet germicide sur les bact\u00e9ries et les virus. Celles-ci sont toujours \u00e9mises par des sources artificielles, comme par exemple des lampes halog\u00e8nes UV-C.<\/span><\/span>\u00a0<\/span><\/span>Dans ce projet, l\u2019hypoth\u00e8se serait de filtrer l\u2019eau courante de Cuba, avec un filtre portable et facilement connectable \u00e0 des bouteilles en PVC.<\/span><\/span>\u00a0<\/span><\/span><\/p>

L\u2019objectif premier, est de mettre en place un outil de pratique, pouvant \u00eatre fabriqu\u00e9 par n\u2019importe quelle personne (ayant acc\u00e8s \u00e0 un Fablab). Pour ce faire, nous avons \u00e9tudi\u00e9 le fonctionnement des objets d\u00e9j\u00e0 pr\u00e9sents dans la soci\u00e9t\u00e9 comme cit\u00e9 plus haut, le filtre \u00e0 \u00e9tang. Pour appuyer notre compr\u00e9hension, des recherches scientifiques se sont dirig\u00e9es vers les techniques pratiqu\u00e9es notamment en Allemagne et France.<\/span><\/span>\u00a0<\/span><\/span>Une fois toutes les informations recueillies, l\u2019\u00e9tape suivante fut de r\u00e9pertorier des pi\u00e8ces standards les plus abordables possible, accessibles partout dans le monde et qui peuvent \u00eatre import\u00e9es \u00e0 Cuba.\u00a0<\/span><\/span>\u00a0<\/span><\/span><\/p>

Au stade actuel, nous avons mis en place une hypoth\u00e8se et un outil exp\u00e9rimental, qui r\u00e9pondent aux crit\u00e8res pr\u00e9c\u00e9demment \u00e9voqu\u00e9s. Pour r\u00e9aliser cet outil, plusieurs \u00e9l\u00e9ments sont n\u00e9cessaires comme une lampe halog\u00e8ne UV-C (12V 9W), un tube en quartz (30cm), un anneau d\u2019\u00e9tanch\u00e9it\u00e9 (d-5cm), une douille (g23) adaptable pour la lampe et une batterie combin\u00e9e avec un transformateur de 5V en 12V (voir jusqu\u2019\u00e0 20V). L\u2019ensemble reviendrait \u00e0 un co\u00fbt estim\u00e9 \u00e0 35 <\/span><\/span>\u20ac (hors frais de livraison) <\/span><\/span><\/p>

Notons que pour l\u2019impression en 3D, il faut veiller \u00e0 utiliser du plastique ASA, qui r\u00e9siste aux UV.\u00a0Il est int\u00e9ressant de\u00a0pr\u00e9ciser\u00a0que la lampe UV-C peut s\u2019illuminer 8000 heures et par ce fait, peut\u00a0filtrer en moyenne 720 000 litres d\u2019eau. <\/span><\/span>\u00a0<\/span><\/span><\/p>\",\r\n \"align\": \"bottom\",\r\n \"row\": 3,\r\n \"col\": 0,\r\n \"colspan\": 1,\r\n \"offsetx\": 0,\r\n \"offsety\": 0,\r\n \"spaceabove\": 0,\r\n \"spacebelow\": 0,\r\n \"yvel\": 1,\r\n \"push\": 0,\r\n \"relid\": 8\r\n }\r\n ]\r\n}","jetpack_sharing_enabled":true,"jetpack_featured_media_url":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-content\/uploads\/2020\/06\/Reimer_Siebels_Thumb.jpg","_links":{"self":[{"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/posts\/263","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/comments?post=263"}],"version-history":[{"count":0,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/posts\/263\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/media\/275"}],"wp:attachment":[{"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/media?parent=263"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/categories?post=263"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/archiexpo.ulb.be\/wordpress\/wp-json\/wp\/v2\/tags?post=263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
