{"product_id":"cefcemt12","title":"FUJIFILM Cation-Exchange Membranes (CEM-Type 12) for Electrodialysis, CEFCEMT12","description":"\u003cp\u003eCEM-Type 12 (Cation Exchange Membrane Type 12, manufactured by Fujifilm Manufacturing Europe B.V.) is a high-performance, cost-effective homogeneous ion-exchange membrane widely deployed in electrodialysis (ED\/EDR), reverse electrodialysis (RED), diffusion dialysis, and wastewater desalination systems. Unlike older-generation, thick heterogeneous membranes, CEM-Type 12 is produced using high-speed continuous roll-to-roll coating technology, combining a cross-linked aliphatic\/aromatic polymer matrix functionalized with sulfonic acid groups onto a thin, mechanically robust reinforcement substrate.\u003c\/p\u003e\n\u003cp\u003eThe main features of the CEM-type12 are: (1) \u003cstrong\u003eLow Electrical Resistance\u003c\/strong\u003e: The thin profile (~ 130 um) and high density of sulfonic acid fixed charges provide low internal ohmic resistance, significantly reducing energy consumption in electrodialysis stacks. (2) \u003cstrong\u003eHigh Monovalent \u0026amp; Divalent Cation Permselectivity\u003c\/strong\u003e: Delivers high transport numbers for standard cations (Na+, K+, Ca^{2+}, Mg^{2+}) while strictly repelling co-ions (Cl-, SO4^{2-}). (3) \u003cstrong\u003eDimensional Stability \u0026amp; Low Swelling\u003c\/strong\u003e: The non-woven composite backing minimizes lateral swelling and distortion during alternating salinity or pH shifts, preventing internal stack leakage. (4) \u003cstrong\u003eWide Chemical Compatibility\u003c\/strong\u003e: Resistant to standard CIP (Clean-In-Place) chemical regimes, including mild acids and caustic washes.\u003c\/p\u003e\n\u003cp\u003eThe primary application fields are: (1) \u003cstrong\u003eElectrodialysis (ED \/ EDR)\u003c\/strong\u003e: Brackish water desalination, industrial zero-liquid discharge (ZLD) concentration, and food\/beverage demineralization (e.g., whey, juice). (2) \u003cstrong\u003eReverse Electrodialysis (RED)\u003c\/strong\u003e: Salinity gradient power generation (harnessing blue energy between river water and seawater). (3) \u003cstrong\u003eIndustrial Effluent Treatment\u003c\/strong\u003e: Recovery of heavy metal cations (Ni^{2+}, Cu^{2+}, Zn^{2+}) from electroplating rinses and acid recovery circuits. (4) \u003cstrong\u003eBipolar Membrane Stacks\u003c\/strong\u003e: Paired with anion exchange membranes (e.g., Fujifilm AEM-Type 12) for acid\/base generation via water splitting.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 101.485%; height: 355px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 36.025px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 36.025px;\"\u003eMembrane Type\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; text-align: center; height: 36.025px;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003eHomogeneous CEM-Type 12\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 36.025px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 36.025px;\"\u003e\u003cem\u003eThickness (um)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; text-align: center; height: 36.025px;\"\u003e\n\u003cp\u003e\u003cspan\u003e110 um\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 36.025px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 36.025px;\"\u003e\u003cem\u003ePermselectivity KCl (0.05-0.5 M)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; text-align: center; height: 36.025px;\"\u003e\n\u003cp\u003e\u003cspan\u003e99%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.8725%;\"\u003e\u003cem\u003ePermselectivity NaCl (0.05-0.5 M)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; text-align: center;\"\u003e\n\u003cp\u003e\u003cspan\u003e99%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 36.025px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 36.025px;\"\u003e\u003cem\u003eElectrical Resistance (2 M NaCl)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; text-align: center; height: 36.025px;\"\u003e\n\u003cp\u003e\u003cspan\u003e5.0 Ω*cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.6625px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 39.6625px;\"\u003e\u003cem\u003eElectrical Resistance (0.5 M NaCl)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; height: 39.6625px;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e6.0 Ω*cm2\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.6625px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 39.6625px;\"\u003e\u003cem\u003eWater Permeation\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; height: 39.6625px;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e2.5 mL\/bar*m2*h\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.6625px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 39.6625px;\"\u003e\u003cem\u003eBurst Strength (wet)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; height: 39.6625px;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e380 KPa\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 37.8725%;\"\u003e\u003cem\u003epH Stability (CIP)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e1-13\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.8875px;\"\u003e\n\u003ctd style=\"width: 37.8725%; height: 55.8875px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 61.8791%; height: 55.8875px;\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e\u003cem\u003e10cm*10cm or 20 cm*20cm or 30cm*30cm\/pcs\/pack\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eLarge sheet sizes also can be supplied upon request. \u003c\/span\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"HZHMKJ","offers":[{"title":"10cm * 10cm","offer_id":48207502672102,"sku":"CEFCEMT12S1010","price":79.0,"currency_code":"USD","in_stock":true},{"title":"20cm * 20cm","offer_id":48207502704870,"sku":"CEFCEMT12S2020","price":229.0,"currency_code":"USD","in_stock":true},{"title":"30cm * 20cm","offer_id":48207502737638,"sku":"CEFCEMT12S3020","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CEFCEMT12_main.jpg?v=1787040350","url":"https:\/\/echemsupplies.com\/products\/cefcemt12","provider":"EChem Supplies","version":"1.0","type":"link"}
