SIX® stands for Suspended Ion eXchange process and is designed to remove Dissolved Organic Carbon (DOC) from the water to improve membrane filtration performance. SIX® also removes sulphate, nitrate, and phosphate. Removal of DOC minimizes membrane fouling and reduces the formation of trihalomethanes (THMs) after final disinfection with chlorination.
The philosophy of the SIX® process is based on an advanced plug flow reactor followed by a specially designed lamella settler. The settled resin is then completely regenerated and re-used. The continuous (modelled) adsorption process operates under stable kinetics.
The design of SIX® itself is far more compact, has lower resin concentration and lower resin inventory, lower salt usage, higher effluent quality and better control of the adsorption process than other processes available anywhere on the market. It allows for the use of different types of resin.
SIX® is leading edge technology, proven and validated as well as completely controllable.
