{"product_id":"cedhcemcmhe","title":"Homogeneous Cation-Exchange Membrane (CMHE) for Electrodialysis (ED) and Bipolar Membrane Electrodialysis (BPED), CEDHCEMCMHE","description":"\u003cp\u003eHomogeneous cation-exchange membranes are a kind of ion-conductive polymer films engineered with uniformly distributed, fixed negative ionic groups (typically strong acid sulfonic groups, -SO3^-) covalently bound across a continuous, single-phase matrix.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eThe critical features of the homogeneous CEM are: (1) \u003cstrong\u003eUniform Ion-Conductive Pathways\u003c\/strong\u003e: Unlike heterogeneous membranes—which disperse ion-exchange resin particles within an inert mechanical binder—homogeneous membranes offer a seamless molecular architecture. This eliminates resistive boundary pockets and ensures an even current distribution across the entire active area. (2) \u003cstrong\u003eLow Area Electrical Resistance\u003c\/strong\u003e: Engineered to maintain minimal electrical resistance (typically around 1.5 to 2.5 Ω*cm2 in standard sodium chloride solutions), drastically cutting down voltage drop and Joule heating during high-current operations. (3) \u003cstrong\u003eHigh Cation Permselectivity\u003c\/strong\u003e: Features powerful Donnan exclusion properties, yielding high counter-ion transport numbers (typically \u0026gt;0.96) that effectively repel co-ions (anions) and maximize current efficiency.\u003c\/span\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eIts main roles in electrodialysis are: (1) \u003cstrong\u003eSelective Desalination\u003c\/strong\u003e: Used to selectively transport target anions (e.g., Cl-, SO4^{2-} ) from a dilute stream into a concentrate stream under an applied electrical field. (2) \u003cstrong\u003eFoulant Mitigation\u003c\/strong\u003e: The smooth, non-porous surface morphology of homogeneous membranes lowers the risk of organic fouling and scaling compared to coarser heterogeneous alternatives, making them ideal for brackish water treatment, wastewater reclamation, and valuable salt concentration.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100.071%; height: 358.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eMembrane Type\/Mode\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eHomogeneous CEM (CMHE series)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eMembrane Thickness (Wet)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e150-280 um\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 39.6px;\"\u003e\u003cem\u003eBurst Strength\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 39.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;0.5 MPa\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eArea Resistance (0.5 M NaCl)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026lt;5.0 Ω cm2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eMaximum Current Density\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e600 A\/m2\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eExchange Capacity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026gt;1.8 mmol\/g dry film\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003eThermal\/pH Stability\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e≤40°C \/ pH: 0-14\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 35.6px;\"\u003e\u003cem\u003ePretreatment\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eNo need\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 55.2px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 55.2px;\"\u003e\u003cem\u003eStorage Conditions\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 55.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eThe AMHN membrane should be keep in hydration status with pure water or 3% NaCl solution. \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 14.2px;\"\u003e\n\u003ctd style=\"width: 33.767%; height: 14.2px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.0192%; height: 14.2px;\"\u003e\n\u003cp\u003e\u003cspan\u003eL10-50cm*W10-50cm\/pcs\/pack\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 \u003c\/p\u003e\n\u003cp\u003eReference: \u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0376738814003329\"\u003eM.C.
