RO EDI Systems for High-Purity, Chemical-Free Water
Many industries require exceptionally high water purity for manufacturing and processing needs. RO EDI (Reverse Osmosis Electrodeionisation) is a proven solution, combining reverse osmosis to remove dissolved solids with electrodeionisation for continuous, chemical-free demineralisation. FILTEC’s RO EDI systems help businesses meet strict water quality requirements while reducing chemical usage, wastewater discharge, and operating costs.
Our RO EDI Solutions
Chemical and Laboratory Water
Laboratories, biotech firms, and specialty chemical manufacturers need precise water quality for research, formulation, and production. FILTEC’s RO EDI solutions deliver consistent demineralised water without the need for chemical regeneration, improving safety and process reliability.
Cooling and Process Water Conditioning
Using high-purity water in cooling systems, heat exchangers, and other critical process equipment reduces scaling and fouling. FILTEC’s RO EDI systems ensure a continuous supply of demineralised water, while lowering maintenance costs and improving operational efficiency.

How RO EDI Works
RO EDI systems combine reverse osmosis and electrodeionisation to produce ultra-pure water. Reverse osmosis removes most dissolved solids, while electrodeionisation uses an electric field and ion-selective membranes to continuously remove residual ions. This eliminates the need for chemical regenerants used in traditional ion exchange systems, offering a cost-effective, eco-friendly solution for high-purity water applications.
FAQs
How does RO EDI differ from a standard reverse osmosis system?
Reverse osmosis removes dissolved solids, but it does not achieve the ultra-pure water quality required for some industries. RO EDI combines reverse osmosis with electrodeionisation to remove residual ions continuously, providing high-purity water without chemical regeneration.
What industries benefit from RO EDI systems?
RO EDI is widely used in pharmaceuticals, electronics manufacturing, power plants, laboratories, food and beverage processing, and other industries requiring ultra-pure water.
How does RO EDI improve sustainability?
RO EDI eliminates the need for chemical regenerants required in traditional ion exchange systems, reducing chemical handling risks, wastewater discharge, and overall environmental impact.
How often does an RO EDI system require maintenance?
RO EDI systems require minimal maintenance compared to traditional deionisation systems. Regular monitoring, membrane cleaning, and occasional component replacement ensure long-term efficiency.
Can RO EDI systems be scaled for different applications?
Yes, RO EDI systems are highly scalable and can be customised for various flow rates and water quality requirements. FILTEC provides tailored solutions to meet specific industry needs.
