A RO-EDI system uses reverse osmosis technology, ion exchange membranes, resin and electricity to deionise water from an ultra-high quality. The purposes of water purification differ from each other, depending on the specific industries that require ultra-pure water (UPW) for their production and processes. Iontech® specialises in this pure water technology and our specialists have an extensive knowledge about many different RO-EDI systems. We always come up with a tailor-made solution that meets your water purification requirements.


Let us advise you on Double Pass RO EDI

The structure of a water purification system depends on the quality of the feed water that has to be purified. When the process requires more, as is the case when purifying sea water, a Double Pass RO offers a fitting solution. Double Pass Reverse Osmosis in combination with EDI technology purifies water in steps to produce pure water in an even purer form. The Double Pass RO technology contains a second RO membrane system that generates a second filtration of permeate water from the first pass. We are always happy to advise you about the necessity and installation of a Double Pass RO system as a pre-treatment to produce ultra-pure water within your specific industry. Choose an efficient, environmental friendly, cost-effective and durable pure water system and enquire after the possibilities for your business.
