CIF® (Continuous Ionic Filtration)
Our CIF® technology combines continuous ion exchange and physical filtration to remove contaminants from water. This technology is proven and built on the foundations of ion exchange, a process that has been used in the water industry for over 50 years, and extensively used globally for hydrometallurgical recovery in mining.
CIF® uses a moving bed of charged resin beads to attract and remove ionic species from water whilst filtering the water of suspended solids, ensuring optimum efficiency and continual high performance. A portion of the resin is cycled between columns (usually hourly) using an air lift pump, allowing continuous operation and regeneration of the system.
Feed water is passed upwards through the ionic bed and exits the top of the filter as treated water. At the same time, the resin is removed from the bottom and passes between columns where it is cleaned, regenerated and returned to the top of the adsorption column.
|✔ Direct treatment of variable input waters with no pre-treatment required||✔ Realises maximum water recovery whilst achieving minimum waste|
|✔ Flexibility in output water quality||✔ Single pass through with rapid processing time|
|✔ Direct capture of solids and ion removal without blocking up or fouling||✔ High plant turn-down rates (up to 90%)|
|✔ Chemicals only required to re-charge resin||✔ Minimal power requirements;|
|✔ Simple materials, no moving parts or complicated internal structures;||✔ Operates at atmospheric pressure (no pressure vessels);|
|✔ Complementary pre-treatment for Reverse Osmosis plants increasing recovery and operational efficiency||✔ Automated operation including compensation for variable feed and produced water requirements|
