ED Ionics Electrodialysis Stack

Summary

Product identification

The Ionics ED Stack is an electrodialysis stack specifically designed with ion exchange membranes, spacers, and electrodes for brine concentration. It is used for salt removal, producing separate dilute and concentrate streams. The stack can be operated in batch or continuous mode. Its modular design allows for easy scaling, with stacks installable in series, parallel, or matrix configurations to achieve desired treatment volumes or target concentrations.

The recommended stack for brine concentration is the 300 cell pair configuration.

Product Features

• Cell pairs of Ionics AR103P and CR61P Membranes designed for salt removal.
• Membrane active area of 0.28 m2/piece.
• Robust stack design capable of Clean-In-Place (CIP), and easily removed and disassembled for cleaning, maintenance, and component replacement.
• Spare parts can be stored on-site.

Materials of Construction

• Welded Frame: Painted Carbon Steel
• Piping: GF PROGEF PP
• Anode: Platinum with metal oxide coatings

Operating limits

Typical Performance

Under typical operating conditions of 250350 A/m2, 0.51.0 V/cell pair, and 1~10% feed solution, the ED system produces:

• A 16 to 20% concentrate stream
• 80 to 90% water recovery
• Treatment volume up to 14 m3/h per stack (300 CP)
• DC energy consumption around 3-8 kWh/mt feed

Feed Stream Guidelines

• Temperature: 40 to 100ºF (4 to 38ºC)
• Typical Feed Concentration: 1-10%
• Operating Pressure: 2-4 bar (28-57 psi)
• Turbidity: < 5 NTU
• TOC: < 60 ppm (mg/l)
• COD: < 200 ppm (mg/l) as O2

Mechanical / hydraulic

For the 300 Cell Pair stack:

• Typical Size (L*W*H): 133.68*71.32*134.34 cm
• Weight: 1130 kg
