FEDI-2 FRACTIONAL ELECTRODIONIZATION 5X, 10X, 20X, 30X AND 45X
FEDI® stacks are designed to produce high purity water up to 18 MΩ.cm using a patented process with double sets of electrodes per stack. The FEDI® stack is designed to replace mixed bed technology and produces pure water continuously, without the use of regenera-tion chemicals. Applications include the semiconductor, power, phar-maceutical, and food and beverage industries.
FEDI-2 is available in two operating modes: Dual Voltage (DV) and Single Voltage (SV). The stacks contain media on the concentrate side, eliminating the need for a salt injection.
• High hardness tolerance – reduces cleaning frequency, while increasing stack reliability
• Apply after a Single Pass RO system, ultimately lowering overall system cost
• Low feed pressure – no counter current operation required
• Improved removal of strongly and weakly ionized impurities
• No concentrate recirculation
• Reduced hardness tolerance
• Excellent product water quality
• High recovery
