The\nsalts are retained by an ion exchange resin, which would usually be regenerated\nwith acid and lye. With electro-deionisation, however, the ions of the resin\nare drawn to the outside by means of an electrical potential difference. The\nspecial membranes only allow charged ions to pass through, as a result of which\nthe last remaining salt can be disposed of via side channels. <\/p>\n\n\n\n<p>After this final step, the\nwater has a purity of approx. < 0.065 \u00b5s\/cm. Via its very own pipeline, it\nis then transported to the steam system of the nearby oilfield. <\/p>\n\n\n<div id=\"gt3pg_gallery1\" class=\"gt3pg_galleryid-1429 gt3pg_gallery-columns-3 gt3pg_photo_gallery gt3pg-corner-type-standard gt3pg_hover-default gt3pg-type-rectangle\" data-size=\"medium_large\" data-type=\"rectangle\" data-corner=\"standard\" data-link=\"lightbox\" data-margin=\"30\" data-instance=\"1\"><dl class=\"gt3pg_gallery-item gt3pg_element\"><div class=\"gt3pg_item_main_wrapper\"><div class=\"gt3pg_item-wrapper\"><a href=\"https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/UPW-Factory-scheme-768x1210.jpg\" class=\"gt3pg_swipebox \" data-description=\"\"><div class=\"gt3pg_img_wrap portrait\" style=\"background-image: url(https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/UPW-Factory-scheme-768x1210.jpg);\" data-width=\"3857\" data-height=\"6075\" data-i=\"1\" >\r\n<img decoding=\"async\" src=\"https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/UPW-Factory-scheme-768x1210.jpg\" title=\"UPW-Factory-scheme\" alt=\"UPW-Factory-scheme\" \/>\r\n<\/div><\/a>\n<\/div>\n <\/div><\/dl>\n<dl class=\"gt3pg_gallery-item gt3pg_element\"><div class=\"gt3pg_item_main_wrapper\"><div class=\"gt3pg_item-wrapper\"><a href=\"https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/cedi-1.jpg\" class=\"gt3pg_swipebox mfp-iframe youtube\" data-description=\"\"><div class=\"gt3pg_img_wrap landscape\" style=\"background-image: url(https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/cedi-1.jpg);\" data-width=\"360\" data-height=\"201\" data-i=\"2\" >\r\n<img decoding=\"async\" src=\"https:\/\/nwtr.nl\/wp-content\/uploads\/2019\/03\/cedi-1.jpg\" title=\"cedi\" alt=\"CEDI-Video\" \/>\r\n<\/div><\/a>\n<\/div>\n <\/div><\/dl>\n<\/div>\n <style type='text\/css'>\r\n\t\t\t#gt3pg_gallery1 .gt3pg_item_main_wrapper {\r\n\t\t\t\tpadding: 15px\r\n\t\t\t}\r\n\t\t\t<\/style>\n\t\t","protected":false},"excerpt":{"rendered":"<p>The last step, a combination of RO and EDI, removes the last dissolved minerals (ions).<\/p>\n","protected":false},"author":1,"featured_media":2257,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[43],"tags":[],"class_list":["post-1429","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-productieproces"],"_links":{"self":[{"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/posts\/1429","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/comments?post=1429"}],"version-history":[{"count":0,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/posts\/1429\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/media\/2257"}],"wp:attachment":[{"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/media?parent=1429"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/categories?post=1429"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nwtr.nl\/en\/wp-json\/wp\/v2\/tags?post=1429"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
