What is EDI?
Electrodeionization is a purification technique in which electric current, selective ion exchange membranes and resin are used to demineralize water and separate dissolved ions (impurities) from the water. This method differs from other processes in that it requires no chemicals to regenerate. It is used exclusively for polishing water that has already been demineralized by reverse osmosis or nanofiltration.
WAV-eDI and WAV-eOI ranges
The WAV-eDI and WAV-eOI ranges are based on the EDI principle, a technology that enables ion exchange without the use of chemicals. This treatment “polishes” the water previously demineralized by the reverse osmosis and nanofiltration processes. The basic models can be upgraded with a host of optional features.
These products are designed to handle flows from 10 to 100 L/h, using a single module. Higher flow rates can easily be handled by adding additional modules, connected in parallel. This ensures even flow distribution to the various modules.
WAV-eDI range devices can be added to existing systems that already include a pre-treatment unit and a reverse osmosis (or nanofilter) unit.
The WAV-eDI range also offers a variety of integrated products, including the WAV-eOI line, which consists of an EDI module grafted (and assembled) to an osmosis plant, providing a turnkey solution for optimal water demineralization.
WAV-eDI and WAV-eOI products can be assembled on complete chassis, including pre-treatment (softener and dechlorinator), distribution and sterilization (UV and microfiltration). Chassis are built to customer specifications.
All models are fully modular, allowing you to program a control system tailored to the needs of each application.
