FS1242EN.doc Jul-13 GE 2020 EDR Systems Electrodialysis Reversal Technology The GE 2020 Electrodialysis Reversal (EDR) product is a proven and reliable desalination technology that has been in service in a variety of industrial and public infrastructure applications. EDR Features ? Use of Carbon Electrodes results in no gas pro-duced and no separate electrode stream required. ? High Water Recovery, up to 94% ? Salt Removal of 50 to 95% ? Polarity Reversal self-cleaning with electricity ? Free chlorine tolerance ? Tolerance to moderate suspended solids ? Adjustable product water performance without blending ? Ability to disassemble stacks for inspection ? Silica tolerance EDR Benefits ? Efficient use of scarce water resources ? Low pretreatment requirements and costs ? Low chemical consumption costs ? Long membrane life, typically 10+ years ? Strong ability to recover from less than ideal feed water quality Standard Design and Scope of Supply ? MK-IV-2 EDR stacks with GE Carbon Electrodes ? Cartridge filter ? Concentrate Recirculation pump with VFD ? GE Fanuc Micro PLC & 12” (30 cm) color Quick Panel HMI ?
