High Capacity Fractional Electrodeionization Stack

June 4, 2013

QUA Fractional ElectrodeionizationQUA®, a developer of advanced membrane products for water and wastewater treatment applications, has launched the "MEGA" line of its FEDI® Fractional Electrodeionization (EDI) products. MEGA FEDI, which will be one of the largest EDI stacks available in the global market, is available in two versions, MEGA FEDI 2 and MEGA FEDI 2–HF, designed to accommodate different feedwater chemistry. MEGA FEDI stacks are ideal for large capacity, high-flow systems normally required in heavy industrial projects such as power, petrochemicals, refinery and electronics for high purity water needs. Each stack can handle treated water flow of up to 75 gallons per minute (GPM), the equivalent of 17 cubic meters per hour (m3/hr). In addition, MEGA FEDI's unique stackable design minimizes piping, reduces footprintand makes it simple and easy to install on skids.
