High ionic removal, Advanced and Plug-and-play.
The EDIpure Advanced units are designed and manufactured to further purify reverse osmosis product water to ultra pure or high purity water (0,055 – 0,5 μS/cm). The Advanced and ‘Ready-to-Run’ units are available in the range from 0,22 m³/h to 7,67 m³/h. The Advanced EDIpure units are rugged, pre-engineered, pre-assembled units that minimize installation and start-up costs. The units are factory pressure tested and require single point utility connections. Their 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 unit is typically re-used and mixed with the RO feed water in a vented break tank.
Control & Construction
EDIpure Advanced units 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 modules are specifically designed for high ionic removal including weakly charged ions like silica, boron and CO2 (up to 18 MOhm.cm).
CEDI technology features:
- Continuous process, constant product water quality
- Low operating costs, electricity only
- Environmentally friendly, no regeneration chemicals
- High unit recovery up to 95%
- Typically the reject water is recirculated upstream RO
- 1000’s units installed worldwide
Unique system design
CEDI system highlights
The Operator Panel (HMI) is located on the electrical cabinet door. This Siemens KTP900 is a 9’’ graphic TFT color display which features a USB interface, 8 function keys and a USB storage device to store historical trending and data. The CEDI operation is displayed as clear and well-arranged P&ID, all relevant screens with associated parameters are easily accessible and user-friendly. The HMI visualizes the control and monitoring performed by the PLC. This Siemens S7-1215 PLC also includes ethernet communication for optional connection to a master PLC or DCS system.
The electrical cabinet is an IP54 rated, ventilated and lockable cabinet which accommodates the power supply, PLC and all electrical controls and connections. The Main Power switch and CEDI system CE plate are located on the electrical cabinet. In case ambient temperature is >35 °C additional air-conditioning can be installed optionally.
