Continuous ion exchange is a new separation technology. It is based on theexisting adsorption, ion exchange and chromatographic separation technology, but different from the fixed bed, pulse bed, simulated moving bed and other separation systems in the traditional sense. It can simultaneously concentrate each working procedure of traditional ion exchange and chromatographic separation in a system, while at the same time carrying out multi-stage separation steps. It can be used for separation,refining,purification and recycling of effective components from industrial feed liquid or impurities removal.
The continuous ion exchange system can use conventional adsorbents, such as ion exchange resins, activated carbon and synthetic adsorbents. Since the continuous ion exchange system runs continuously and need not to set up an alternate device, the ion exchange resin does not need to interrupt normal production during regeneration. Since multi-column adsorption and run continuously at a steady state, it can handle materials with higher concentrations of impurities to ensure the product has a stable composition and concentration. Meanwhile, the system has multiple channels and can change the flow direction of the fluid according to process requirements. Because it enables to operate multi-stage separation procedures at the same time, the more complex the separation process is, the better it can exert its advantages.
Reduce 50-90% of separation media.
1Handle materials of higher concentrations, and due to the continuous operation, the product composition and concentration are stable after absorption or ion-exchange.
2Reduce about 30-65% of chemicals and eluents; reduce 30-85% of wastewater emissions.
3The system is compact; the original fixed-bed processes are all focused on this system to avoid investment duplication of equipment and reduce50-80% of floor space.
4The system is easy to match other devices, under full automatic control, and is easy to operate and control.
