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.

PWNT’s In-Line Coagulation and Adsorption (ILCA®) process was developed to minimise coagulation/flocculation footprint and to simplify pre-treatment upstream of CeraMac®. For most surface waters, coagulated feed water lowers the ceramic membrane fouling rate, but strong, large, setting flocs are not required for filtration with ceramic microfiltration.
