An EDI module is one component of a system and must match upstream water quality, the electrical supply and downstream requirements. Illustrations show modules and connections but cannot establish membrane material, model or product-water resistivity.
Applications and the starting point for selection
For projects with documented process-water requirements, first compare upstream treatment results with the module's specified feedwater conditions. Permitted ranges differ between modules; a general technology overview must not be presented as the performance of modules shown on this site.
Equipment, interfaces and site conditions
Confirm the complete model, every connection, power and control requirements, and monitoring arrangements. Define the delivery scope for the module and the complete system. When replacing a module, also check adjacent pumps, valves, instruments and control documentation.
Maintenance and handover
Record module operating conditions and system changes, and handle abnormalities according to the relevant documentation. One instrument reading cannot replace full acceptance testing. A module's appearance does not establish suitability for medical or other specialised uses.
| Item to check | Information and operating basis |
|---|---|
| Complete model information and upstream water quality | Obtain documentation for the relevant model or site and record the source, date, applicable conditions and person responsible. Leave incomplete information pending confirmation. |
| Connection and electrical documentation | Obtain documentation for the relevant model or site and record the source, date, applicable conditions and person responsible. Leave incomplete information pending confirmation. |
| Downstream requirements and monitoring points | Obtain documentation for the relevant model or site and record the source, date, applicable conditions and person responsible. Leave incomplete information pending confirmation. |
| Delivery scope for the module and complete system | Obtain documentation for the relevant model or site and record the source, date, applicable conditions and person responsible. Leave incomplete information pending confirmation. |

Scope of this information:Compiled on 4 October 2026 from the available equipment-themed material. Equipment images are AI-assisted illustrations. This page presents possible configurations and is not evidence of a specific model, supply list, test approval, licence or completed project. The actual model, operating conditions and intended use must be confirmed against the relevant documentation. Prices, warranty and installation scope are subject to the written agreement for each order.
RO permeate is not automatically suitable feedwater for every EDI module
Check module feedwater against each requirement in the documentation for that model, rather than relying on nominal RO output or a single conductivity reading. Obtain test, operating and interface information before confirming the available model and compatibility. Do not enter threshold values without documentary support.

A document's scope matters more than a high resistivity figure
The DuPont EDI-310 datasheet illustrates how a manufacturer specifies feedwater and operating conditions. This page does not apply those values to other Gudian modules or complete systems. A module datasheet, site test results and the final point of use concern different parts of the assessment. Specialised applications require a separate review of the applicable requirements.
Continuous regeneration in EDI does not mean that the entire water treatment system uses no chemicals, needs no maintenance or produces no discharge. Upstream treatment, cleaning, storage and operating management must be reviewed separately. Follow the actual module documentation for replacement and electrical work.
