from IX to SIXfrom IX to SIX

® ®



IX process demands

capable of treating raw surface water

choice of multiple resins (suppliers)

no resin ‘blinding’ and/or loss



‘state of the art’ on IX

mainly used in industry (ultrapure water)

no large scale applications on raw surface water

there is a world wide wish to use IX on waters

containing suspended solids(direct treatment of surface water)

current available technology’s: ®



limitations fluidized bed IX

never used for large scale applications(>1000 m3/h)

– large volume of regeneration solution

– discontinues adsorption process effluent quality depending on flow, time and

influent quality

resin ‘blinding’ occurs due to biofilm formation



limitations MIEX ®

major part of the resin is re-circulated or re-usedwithout regeneration leading to:

–

– resin ‘blinding’

– high resin concentration and/or contact timesres n an tec no ogy can on y e purc ase romone supplier

summary SIX ®

SIX process fulfills demands

advantages SIX compared to existing ion

– no resin ‘blinding’

– compact resulting in a low footprint – low resin concentration

– low resin inventory

– high effluent uality

– reliable model to design pilots and full-scaleinstallations
