Cation resins eliminate positively charged ions while anion resins delete negatively charged ions.<\/li>\n<li><strong>Distillation:<\/strong> Water is heated to a gaseous state and recondensed in a separate vessel.<\/li>\n<li><strong>Filtration<\/strong>: Use as a stand-alone treatment or a pretreatment. At normal line pressures, water passes through a filter of specified porosity. The filter retains most particulates, with water passing through.<\/li>\n<li><strong>Reverse Osmosis:<\/strong> Use primarily as a pretreatment. In a U-tube, a semipermeable membrane separates equal amounts of saline solution and pure water. When the saline side experiences external pressure, the semipermeable membrane enables water to pass through while salts are concentrated and flushed down a drain.<\/li>\n<li><strong>Ultrafiltration:<\/strong> Use for removing bacteria and pyrogens. Water is forced under pressure through a membrane (with a pore size smaller than 0.005 \u00ecm). Particulates remain, with only pure water passing through.<\/li>\n<li><strong>Ultraviolet (UV) Oxidation:<\/strong> UV light (at &lt;280 nm) passes through water, which destroys bacteria, viruses, and trace organics.<\/li>\n<\/ul>\n<p><em>See all of our <\/em><a href=\"https:\/\/www.coleparmer.com\/Category\/Water_Purification\/7159?referred_id=5618\" target=\"_blank\" rel=\"nofollow noopener noreferrer\"><em>water purification<\/em><\/a><em> options.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Depending on your water purification needs, you may use one of several processes to purify water: Adsorption: In this process, activated carbon bonds with chlorine and organic materials in feedwater to immobilize and remove these&#8230;<\/p>\n","protected":false},"author":20,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10,13],"tags":[569,1733],"class_list":["post-4453","post","type-post","status-publish","format-standard","hentry","category-filtration-2","category-for-the-lab","tag-filtration","tag-water-purification"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.7 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>How Pure is Your Water?
