Pure-Water - Model EDIpure Advanced -Continuous Electrodeionization (CEDI) System
Our EDIpure Advanced Continuous Electrodeionization (CEDI) systems based on the LXM-X module are designed and manufactured to further purify reverse osmosis product water to ultra pure or high purity water (0.055 – 0.5 µS/cm). These pre-engineered and ready-to-run CEDI systems are fully factory acceptance tested to significantly reduce installation and start-up costs and are available in a range from 0.22 to 7.67 m3/h. The outstanding design and use of Ionpure’s® patented continuous electrodeionization technology ensures high reliability, minimizes maintenance and eliminates use of regeneration chemicals.
How it works.
The water passing through the product compartments is deionized to pure water, while the rest of the water is flowing into the reject compartments. This water takes away concentrated salts and small amounts of gases formed on the electrode surfaces. The reject water exiting the CEDI system is typically re-used and mixed with the RO feed water in a vented break tank.
EDIpure Advanced systems are skid mounted and include a sophisticated control system based on standard PLC / HMI interface and all necessary instrumentation for a reliable and continuous operation. The control system allows easy integration of feature options and auxiliary communication via Ethernet, Modbus or Profibus. Piping is available in PVC, PP or Stainless Steel. These CEDI systems are specifically designed for high ionic removal including weakly charged ions like silica, boron and CO2 (up to 18 MOhm.cm).
