E-Cell EDI Stack Features And Benefits
• Low energy consumption
• Leading product water quality, in part due to ion exchange resin filled concentrate and dilute channels as well as a patented ion exchange resin arrangement
• Counter-current operation reduces the possibility of scale formation
• Strong reputation for reliable operation
• Simplified system design does not require degassing the concentrate, a concentrate recirculation loop, or added salts
