Standard deionized water production single-skid unit

The TERION™ S combines single-pass reverse osmosis and continuous electrodeionization to produce high grade deionized water which meets the highest global lab, power and industrial standards.

TERION™ S is a standardised single-skid unit combining reverse osmosis (RO) and continuous electrodeionization (CEDI) designed to produce deionized water up to 18  MOhms/cm. The product family includes 7 models all compliant with European regulations for the laboratory, power and general industry. Plug & play unit suitable for transportation into a container, allowing short lead times, quick installation and start-up.
The combination of these technologies ensures a salt rejection rate of over 99.5% through the high pressure RO membranes and the latest generation of CEDI to ensure continuous production.
