What is IonPro™ ?

The Ionpro is an integrated, compact, user-friendly water purification system that combines the performance of reverse osmosis (RO) with continuous electrodeionisation (CEDI) to produce high-purity water with low bacteria levels. The technology is ideal for use across cosmetics, pharmaceutical, microelectronics, central laboratory (analytical grade II water) and general manufacturing applications.

Ionpro integrated water purification system is pre-engineered and housed in a single compact portable cabinet. The system is capable of producing between 570 to 1,000 l/h of high-purity water. Its plug-and-play design means it can be connected on site directly to the main tap water supply in order to produce high-purity bacteria-free water. The produced water exits the system at approximately two bar pressure and can then feed a distribution loop or a process tank.

How Ionpro works

The feedwater is first filtered and softened to eliminate particles and hardness and to reduce organic level. Next, the filtered stream flows parallel to the reverse osmosis membrane surface.

The CEDI module then uses ion exchange resins to purify RO water by capturing dissolved ions. Electric potential drives captured cations through the cation membranes and captured anion through the anion membranes.

  • Cation permeable membranes transport cations out of the diluting compartment, but prevent anions from leaving the concentrate compartment.
  • Anion-permeable membranes transport anions out of the diluting compartment, but prevent cations from leaving the concentrate compartment.

Finally, the waste stream removes concentrated ions from the system and produced water leaves the system.

The membranes, CEDI module and piping are sanitized with our water treatment chemical, Hydrex 4203.


New IonPro generation provides one advanced control system for multiple process technologies (softening, reverse osmosis, CO2 removal with membrane degasser or alkaline pH regulation, continuous electrodeIonisation, ultra violet as post-treatment) in a single packaged product. The RO40 controller in conjunction with new user-friendly HMI enables the equipment to communicate via Hubgrade for data monitoring. Using low energy VRO membranes, Variable Frequency Drive (VFD) and IE3 HP pump motor respect the green sustainability concept of energy and water consumption while maintaining the purified water output in line with current Pharmacopoeia.
