EDI (Electrodeionization)
for the production of Ultrapure water
TITAN® EDI for the production of
Ultrapure water
EDI, or Electronic De-Ionization, is a post-treatment technique used to produce ultrapure water. By combining techniques that all together look very much as a mixture of membrane filtration, ion exchange and electrolysis, residual salts present in the water are removed and ultrapure water with a very low conductivity remains. This water is ready for use in the pharmaceutical industry, boiler feed water, steam production, AUS32 (diesel exhaust fluid) production, or Hydrogen production.

What is EDI
Electrodeionization?
At Remon, we produce ultrapure water in a modern and environmentally friendly way using our TITAN® EDI. But what is EDI? Whereas membrane separation and ion exchangers with chemical regeneration were previously used, EDI (electrodeionization) combines these techniques with an electric field. Dissolved particles are moved and removed based on their electrical charge.
Thanks to this technology, the resins in the system do not require manual or chemical regeneration — this happens automatically with electricity. As a result, the use of harmful chemicals is almost eliminated. Compared to traditional methods, up to 95% less acid and alkali are used.
EDI (electrodeionization)
How does it work?
An EDI cell consists of chambers filled with specific resin, sandwiched between multiple special membranes: one for positively charged particles (cations) and one for negatively charged particles (anions). Only the dissolved ions can pass through these membranes, while the water itself remains in the chamber.
As water flows through the chamber, the resin removes the ions. By applying an electric current perpendicular to the water flow, these ions are moved into separate side compartments, preventing them from remaining in the system. The membranes ensure the ions cannot return, maintaining continuous purification.
Additionally, the electric current causes water molecules on the resin surface to split into hydrogen and hydroxide ions. These ions keep the resin in excellent condition without the need for added chemicals.

Remon TITAN® EDI
The TITAN® EDI systems from Remon are fully developed in-house and feature cells from a Western manufacturer to ensure the final ultrapure water quality. The systems are equipped with a color touchscreen and offer full online control. They have a high-quality finish and are mounted on a stainless steel skid with a fiberglass grid.
As pretreatment, a water softener and a membrane filtration system with reverse osmosis must always be used first. This ensures the water is of sufficient quality for EDI treatment. Combined with TITAN® membrane filtration, the TITAN® EDI removes more than 99.9% of ions from the water. In practice, this product is also called a demineralization street.
TITAN® EDI - High-quality ultrapure water
For various applications
Remon’s TITAN® EDI solutions are suitable for any application requiring continuous, cost-effective removal of impurities from water without using hazardous chemicals. This includes processes involving wastewater reuse or where high water purity is essential for production or cleaning.
Whether for the food industry, chemical production, laboratories, or pharmaceutical applications, the system delivers reliable, ultrapure water directly from the installation. This makes it ideal for feeding steam boilers or rinsing microelectronics.
The TITAN® EDI system supplied by Remon meets—and often exceeds—the standards for ultrapure water. If the system becomes temporarily contaminated, water quality can be fully restored after cleaning, ensuring process continuity and quality.
