{"product_id":"cfcditc","title":"Flow Electrode Capacitive Deionization (FCDI) Test Cell, CFCDITC","description":"\u003cp\u003eIn the field of electrochemical water treatment, Flow Electrode Capacitive Deionization (FCDI) is an advanced evolution of traditional CDI. Unlike standard CDI, which uses static film electrodes that eventually saturate, FCDI uses a flowing carbon slurry (the flow electrode), allowing for continuous desalination without the need for a regeneration cycle. A typical FCDI test cell is a complex assembly that combines the principles of a plate-and-frame filter press with the fluid dynamics of a flow battery.\u003c\/p\u003e\n\u003cp\u003eThe test cell is generally symmetrical, consisting of several stacked layers: (1) \u003cstrong\u003eCurrent Collectors\u003c\/strong\u003e: Usually made of high-purity Graphite plates or gold-coated titanium. They provide the electrical contact to the flowing slurry. (2) \u003cstrong\u003eFlow Channels\u003c\/strong\u003e: Often CNC-machined into the graphite plates (serpentine or parallel patterns) to guide the carbon slurry. (3) \u003cstrong\u003eIon Exchange Membranes (IEMs)\u003c\/strong\u003e: The AEM (Anion Exchange Membrane) is positioned near the positive electrode to allow anions (Cl-) to pass, while the CEM (Cation Exchange Membrane) is positioned near the negative electrode to allow cations (Na+) to pass. (4)\u003cstrong\u003e Saline Water Chamber (Spacer)\u003c\/strong\u003e: A middle compartment (often separated by a nylon mesh spacer) where the brackish water or seawater flows to be desalinated. (5) \u003cstrong\u003eEnd Plates\u003c\/strong\u003e: Stainless steel or acrylic plates that bolt the entire stack together to ensure a leak-proof seal.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 528.45px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCFCDITC (C-FCDI-FTC)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 126px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 126px;\"\u003e\u003cem\u003eStructure\/Components\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 126px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eFlow Plate: Graphite with serpentine channels\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupporting Plate: Acrylic material\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eElectrode Distance: 1.5 mm\u003c\/li\u003e\n\u003cli\u003eTubing Connection Port: M5-3.8 (suitable for I.D. 4mm soft tubing.  \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 54px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 54px;\"\u003e\u003cem\u003eCell Manifold Size \u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 54px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e4 cm * 5 cm (Channel width \u0026amp; depth: 2mm*2mm; Effective contact area with membrane: 10.9 cm2; Inner cell volume: 2.18 mL).
