BUILT AROUND YOUR WATER
Not Just a Standard EDI Machine
EDI performance depends heavily on the quality of the water entering the EDI module. For most projects, suitable RO permeate is used as the EDI feed.
RO Permeate First
The EDI section should receive suitable RO permeate. Upstream pretreatment and RO configuration are selected according to the original feed water.
Target Conductivity Matters
The polishing concept, EDI module selection and monitoring points should be matched to the verified final-water quality requirement.
Integrated Monitoring
Conductivity or resistivity monitoring can be arranged at key points across the RO and EDI treatment train according to the project.
Core Components of an RO System
Pump brands, piping materials and RO membrane options can be selected according to project budget, water quality, hygiene requirements and local service preferences.
Water Pump
Choose the pump brand according to project budget, duty point, local service requirements and customer preference.
Pipe Material
Select piping based on hygiene level, corrosion resistance, project budget and application requirements.
RO Membrane
Choose the RO membrane brand, element size, and array based on factors such as water quality, flow rate, local services, and budget.

DESIGN EXAMPLE
From RO Permeate to High-Purity Water
Aquaclarion first evaluates the original source water and required final-water standard. The pretreatment and RO stages are then designed to provide stable EDI feed water. The EDI module, instrumentation, storage and distribution system are selected around the required 4,000 L/h product-water flow and conductivity or resistivity target.

What we need before quotation
Send us the feed-water source, available water-analysis report, required final-water flow, operating hours, application, target conductivity or resistivity, storage requirement and distribution-loop information. These details allow us to select the appropriate pretreatment, RO configuration and EDI module.
Can Electrodeionization treat raw water directly?
EDI is normally used as a polishing stage after suitable upstream purification, commonly reverse osmosis. The original source water still determines the pretreatment and RO design.
What feed water does the EDI module require?
The EDI module should receive suitable reverse osmosis (RO) permeate. Typically, the incoming liquid must have a conductivity of 1–10 µS/cm. However, the actual requirement depends on the selected EDI module and the project design.
Can the system achieve 18.2 MΩ·cm resistivity?
Water quality approaching 18.2 MΩ·cm may be achievable with an appropriately designed and controlled treatment and distribution system. It should not be treated as a universal specification for every RO + EDI project. The complete system may require additional polishing, sanitary storage, recirculation and properly compensated resistivity monitoring.
Can UV or additional polishing be added after EDI?
Yes. UV and other post-treatment or polishing stages can be added when required by the application and final-water quality specification.
How much water can the system produce per day?
At a rated product-water flow of 4,000 L/h, the theoretical output is up to 96 m³ per day when operated continuously for 24 hours. Actual daily output depends on operating hours, feed-water conditions, cleaning or maintenance time and system availability.
