RO+EDI Ultrapure
RO+EDI Ultrapure Water System
For higher water quality after RO treatment. RO+EDI ultrapure water systems for electronics, precision manufacturing, laboratories, photovoltaic cleaning, and high-purity water applications.
Product overview
Use EDI when RO water is not clean enough for the process
EDI is not required for every pure water project. It becomes important when the buyer has clear requirements for resistivity, ionic residue, TOC, particle control, or stable high-purity water at the point of use.
Compared with traditional ion exchange, an RO+EDI system can reduce acid and alkali regeneration work and support continuous production. Common target resistivity can be designed toward 15-18.2 MOhm-cm according to the project requirement.
Buyer focus
Continuous ultrapure water with less chemical regeneration
Compared with traditional ion exchange, an RO+EDI system can reduce acid and alkali regeneration work and support continuous production. Common target resistivity can be designed toward 15-18.2 MOhm-cm according to the project requirement.
Reduce most dissolved salts before EDI.
Further remove ions and stabilize high-purity water.
Configure polishing resin, UV, final filter, and distribution loop if required.
EDI advantage
RO+EDI is designed for continuous high-purity water demand
For buyers comparing traditional ion exchange and EDI, the key differences are regeneration method, continuous operation, water quality stability, and maintenance workload.
| Item | Traditional ion exchange | RO+EDI system |
|---|---|---|
| Regeneration | Requires acid and alkali regeneration. | Electrodeionization supports continuous regeneration. |
| Operation | Regeneration cycles may interrupt water supply. | Suitable for continuous high-purity water production. |
| Water quality | Water quality can fluctuate with resin condition. | Common target resistivity can be designed toward 15-18.2 MOhm-cm. |
| Maintenance | More chemical handling and regeneration management. | Less chemical regeneration work and easier daily monitoring. |
