Typical Properties of Granular Activated Carbon<\/span><\/b><\/u><\/p>\n Iodine and molasses<\/b> numbers measure pore size distribution.\u00a0 Iodine number is a relative measure of pores at sizes of 10 to 2 Angstroms. It is reported in milligrams of elemental iodine adsorbed per gram of GAC and determines the area available on the GAC to adsorb low molecular weight organics.<\/span><\/p>\n Molasses<\/b> number measures the degree a GAC removes color from a stock solution. It measures pores greater than 28 Angstroms. These are the pores responsible for removing larger molecular weight organics such as tannins.<\/span><\/p>\n Abrasion<\/b> numbers represent the relative degree of particle size reduction after tumbling with a harder material. No reduction is rated 100, complete pulverization is zero.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" Typical Properties of Granular Activated Carbon Bituminous Sub-bituminous Lignite Nut Shell Iodine Number 1,000-1,100 800-900 600 1,000 Molasses Number 235 230 300 0 Abrasion Number…<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"footnotes":"","_jetpack_memberships_contains_paid_content":false,"jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false}}},"categories":[18,10],"tags":[119,117,118],"jetpack_publicize_connections":[],"yoast_head":"\n\n\n
