PRODUCT DETAILS
Electrodeionization (EDI)isawater treatment technology thatutilizes a electricity, ion exchangemembranes and resin to deionizewater and separate dissolved ions(impurities) from water.
It differs from other waterpurification technologies in that itis done without the use ofchemical treatments and is usuallya polishingtreatment to reverseosmosis (RO)
Continuouselectrodeionization(CEDI)means that the electriccurrent regenerates the resin masscontinuously.CEDl techniquecanachieve veryhigh puritywithconductivity below 0.1 uS/cm.
Filtration Rating:0.1 nm
Desalination Rate: 99.99%
Conductivity ≤0.1 us/cm

We provide professional consultation and customized solutions for water treatment equipment. Welcome to contact us for cooperation.
Q: What purity level does your RO+EDI plant produce?
A: Our systems generate ultra-pure water with resistivity up to 18.2 MΩ·cm (25°C), meeting standards for semiconductors, pharmaceuticals, and power generation.
Q: Do you offer customized solutions for unique water treatment needs?
A: Yes, we design and manufacture tailor-made plants to meet specific flow rates, space constraints, and strict water quality standards.
Q: What is the typical service life of your water treatment equipment?
A: With proper maintenance and consumable replacement (e.g., membranes, filters), our plants operate efficiently for 10–15 years. EDI modules last 5–8 years, while RO membranes require replacement every 2–3 years.
Q: How do I select the right water treatment plant for my industry?
A: Selection depends on feed water quality, required product water purity, industry (e.g., pharmaceuticals, electronics), and flow rate demand. Our technical team can analyze your water sample and provide a customized recommendation.
Q: What is the difference between RO, EDI, and UF water treatment technologies?
A: Reverse Osmosis (RO) removes dissolved salts, organics, and most contaminants via a semi-permeable membrane. Electrodeionization (EDI) further purifies water by removing residual ions using electricity and ion exchange resins. Ultrafiltration (UF) filters out suspended solids, bacteria, and large molecules but does not remove dissolved salts.
