Electrodeionization
Elmatec incorporates electrodeionization stacks on turnkey units to respond to your specific problems or requirements. An electrodeionization stack is composed of cationic and anionic membranes, ion exchange resins and an anode (+) and a cathode (-) at the ends. When an electric current is applied, the cations and anions migrate through the water to be treated. The cationic membranes let through the cations attracted by the cathode, and the anionic membranes let through the anions, attracted by the anode. The […]
Reverse osmosis
Elmatec designs and manufactures turnkey reverse osmosis units to address your specific problems or requirements. Osmosis is a natural phenomenon in which a « pure » solution naturally passes through a semi-permeable membrane to dilute a « concentrated » solution of mineral salts. The osmotic pressure corresponds to the balance between the two compartments. Reverse osmosis involves applying pressure to the salt water compartment to force water through the semipermeable membrane to produce purified water. For this water to pass through the membrane, the […]
Hollow fiber ultrafiltration
Elmatec designs and manufactures turnkey ultrafiltration units to address your specific problems or requirements. Ultrafiltration is a membrane separation process that aims to retain particles contained in a fluid. The fluid is filtered under pressure through a porous medium, the membrane. The membrane traps particles larger than 0.02 µm. Ultrafiltration thus makes it possible to obtain water that is free of suspended solids and colloids while also providing a physical barrier against bacteria and viruses. The ZEEWEED range by Suez offers […]
Cartridge filtration
Elmatec offers a wide range of filters to suit your specific needs and requirements. Cartridge filtration is a separation process that aims to retain particles (e.g. suspended solids, colloids, etc.) contained in a fluid. The fluid is filtered through a porous medium, the cartridge, under pressure. Only particles smaller than the pore diameters pass through the media. Sterilizing filtration is achieved when low cut-off levels are reached to retain microorganisms (according to ASTM F838-15). Nominal and absolute filtration Filtration performance […]
