Electrosep, Inc has developed a non-fouling electrolytic membrane technology capable of extracting specific target ions
from industrial process streams that contain high concentrations of organic and inorganic solids. The company owns several patents on non-fouling electrolytic membrane
technology including a variety of applications in water and wastewater treatment for the industry.
Electrosep's Non-fouling Electrolytic Membrane Cell
The non-fouling EL-membrane cell developed by Electrosep is modular in design. Overall capacity of EL-processes can be
easily expanded for treatment of millions of gallons per day.
The electrolytic membrane cell consists of a patented mechanism that generates turbulent-flow to avoid
fouling of membrane and electrodes in the cell when treating streams containing high solids concentrations. This technology is
capable of treating process streams with a single-step operation that uses low voltage electrical current to extract desirable
molecules or remove undesirable ions.
Electrochemical Reactions in Electrosep's Membrane Cell
The new membrane technology operates at lower voltages, reduces energy cost, and performs unique electrochemical reactions in a wide range of applications. The industry can
now consider treatment of process streams that have been difficult to treat with conventional filtration equipment.
The above diagram describes the basic electrochemical principles by which Electrosep's cell works. As the stream to be treated passes through the anolyte chamber,
sodium (Na+) ions are transferred through the membrane to the catholyte chamber to combine with available hydroxyl (OH-) ions and produce caustic (sodium hydroxide).
Organics are oxidized or acidified at the anode, allowing them to be removed from the treated stream. Hydrogen gas (H2) is liberated at the cathode, and may be recovered for fuel.
