ED itself is a membrane used to carry ions under the influence of an electric potential. ED membranes have several advantages, including high filter selectivity, low electrical resistance, and high chemical stability.<\/span><b><\/b><\/p>\n<figure id=\"attachment_68959\" aria-describedby=\"caption-attachment-68959\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-68959 size-large\" src=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02-1024x579.jpeg\" alt=\"Ilustrasi penggunaan gabungan membran untuk mengurangi konduktivitas listrik pada air hasil produksi pulp dan kertas yang digagas oleh Tim Winini ITS\" width=\"1024\" height=\"579\" srcset=\"https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02-1024x579.jpeg 1024w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02-300x170.jpeg 300w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02-768x434.jpeg 768w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02-355x201.jpeg 355w, https:\/\/www.its.ac.id\/news\/wp-content\/uploads\/sites\/2\/2022\/06\/WhatsApp-Image-2022-06-02-at-15.33.02.jpeg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-68959\" class=\"wp-caption-text\"><span style=\"color: #0e101a\">Illustration of the combined use of membranes to reduce electrical conductivity in water produced by pulp and paper, which was initiated by the ITS Winini Team<\/span><b><\/b><\/figcaption><\/figure>\n<p style=\"text-align: justify;background: white;margin: 0cm 0cm 7.5pt 0cm\"><span style=\"color: #0e101a\">This 2021 student initially continued that the wastewater from pulp and paper products will be processed in a flocculation tank to remove the impurity particles.
