Ion-Exchange Column/Bed Processes TRIZ Cases
- Heating Water Treatment with Buffered pH Stabilization
A buffered pH stabilizer keeps treated heating water at pH 8-11 after ion exchangers saturate, reducing scale and corrosion.
- Cooling Path Ion Cleaning to Cut Conductivity Without Losing Rust Protection
Removable ion exchange resin cleans coolant ions before additives are restored, lowering conductivity and corrosion risk without losing rust protection.
- Mixed-Bed Ion Exchange Filters for Thermally Stable Coolant Purification
A mixed resin bed in H, OH, and HCO3 forms removes coolant impurities while maintaining thermal stability and low conductivity.
- LFP Battery Black Mass Recycling via Selective Leaching and Ion Exchange
Selective alkaline and acid leaching with ion exchange removes fluoride and copper, enabling high-purity iron phosphate recovery from LFP black mass.
- Aluminum Adsorption Resin Regeneration in Lithium Battery Recycling
Distilled water desorbs aluminum from an adsorption resin column, cutting chemical regeneration, wastewater treatment, and recycling cost.
- Lithium Battery Recycling Resin Column Without Chemical Regeneration
Distilled water desorbs aluminum from a resin column in lithium battery recycling, reducing chemical regeneration, cost, and waste.
- Packed-Bed Lithium Purification Without Intermediate Wash Stages
A three-column lead-lag adsorption and desorption cycle removes wash stages to improve lithium purification uptime, flow, and cost.
- Multi-Point Ion Exchange Vessel Layout for Uniform Media Saturation
Multiple injection points distribute contaminated fluid evenly in ion exchange media, preventing hot spots and reducing heat and hydrogen risks.
- Composite Extractant Resin for Rare Earth Slurry Phase Separation
A composite extractant resin recovers rare earths from acid-leaching slurries while limiting emulsion, solvent loss, and poor phase separation.
- Anion Exchange Resin Separation of Lead-212 and Bismuth-212
An anion exchange resin captures lead-212 and bismuth-212 together for fast, high-purity separation from the thorium-232 decay chain.
- Polyether Polyol Purification Using Weak-Acid Ion Exchange Beds
Weak-acid cation resin followed by a mixed ion exchange bed removes alkali ions while limiting 2M2P odor formation in polyether polyols.
- Extracorporeal Adsorbent Filtration for Viral Mediator Removal
Sequential SCP and ion-exchange adsorption removes disease mediators from bodily fluids to support treatment of viral immune suppression.
- Anion Exchange Resin Deacidification for Diester Hydrogenation
Removing maleic acid monoester from the diester stream with anion exchange resin prevents catalyst deactivation and polymer buildup before hydrogenation.
- Continuous Lithium-Sodium Separation With Multi-Column Resin Switching
A multi-way valve and staged resin columns enable continuous lithium-sodium separation with over 95% recovery and lower operating cost.
- Mixed-Mode Chromatography Resins for Selective Biomolecule Purification
Dual anionic exchange and hydrophobic ligands improve biomolecule separation, enabling cleaner bind-elute or flow-through purification.
