However, this method requires a high pressure and substantial amounts of electricity. The membrane often clogs up, reducing the efficiency of the process.<\/p>\n<p>The new technique, developed by a team of scientists from the Universities of Bath, Swansea and Edinburgh, doesn\u2019t use any external pressure but instead uses a small amount of electrical energy to pull chloride ions through the membrane towards a positively charged electrode. This causes water molecules to be pushed through at the same time as the chloride, a bit like a piston. Meanwhile, sodium ions remain on the other side of the membrane, attracted to the negatively charged electrode.<\/p>\n<p>The chloride ions are then recycled back into the chamber containing the salt water and the process is repeated, gradually drawing more and more water molecules through. Professor Frank Marken, from the University of Bath\u2019s Water Innovation Centre and Institute for Sustainability led the study, and predicts this could be used on a small scale where drinking water is needed but there is not the infrastructure available, such as in remote areas or disaster zones.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.swansea.ac.uk\/press-office\/news-events\/news\/2023\/09\/new-method-for-purifying-drinking-water-could-be-used-in-disaster-zones.php\">Swansea University<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/4-405\/\">New method for purifying drinking water could be used in disaster zones<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[11632,5423,575],"class_list":["post-117233","post","type-post","status-publish","format-standard","hentry","category-news","tag-disaster-zone","tag-drinking-water","tag-environmental-news-en"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117233","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=117233"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117233\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=117233"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=117233"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=117233"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
