CIF® is based on the foundation of IX technology, and can be compared to continuous sand filtration. In CIF®, charged resins are used as filtration media instead of sand, and in addition to removing suspended solids, CIF® also ‘filters’ dissolved salts out of the solution.
Three main processes based on CIF®:
Single stage CIF® for resource recovery and dealkalisation applications
Dual stage CIF (DeSALx) for desalination of water
High recovery reverse osmosis (HiROx)
All three systems can be adapted to produce a zero liquid discharge (ZLD) process.
