Our solutions
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.
With SIX®, Ceramic Micro Filtration, UV H2O2 treatment and GAC filtration as unique, innovative components for fully integrated, sustainable water treatment processes, based on process fundamentals, mathematics and hydraulics and real world testing, PWNT experts are able to provide end-users with custom-oriented solutions.
