QUA FEDI - Model HF -Fractional Electrodeionization (FEDI) Process

FEDI stacks are designed to produce ultrapure water up to 18 MΩ.cm using a patented process with double sets of electrodes per stack. FEDI replaces mixed bed technology and produces pure water continuously without the use of regeneration chemicals. The stacks are designed for operation after double pass reverse osmosis. The stack has ability to produce ultrapure water with high flow rate using a patented “Split Flow EDI” technology. Applications include the semiconductor, power, food & beverage and pharmaceutical industry.
