Water Softening TRIZ Cases
- Recycled CaCO3 Carpet Backing Without Sand Contamination
Wastewater-softening CaCO3 is grafted onto grain to avoid sand contamination, enabling carpet backing with lower tool wear.
- Ironing Water Treatment Layout for Fast Scale-Free Steam Supply
A separate low-flow electrode container demineralizes water before steaming, cutting scale risk and avoiding user wait time.
- Iodophilic Electrode Capture and Release of Iodide From Water
An iodophilic electrode oxidizes iodide to iodine inside the electrode, then releases it into a second solution for selective water treatment.
- PFAS Destruction Reactor With Membrane Reject Recycling
UV treatment recycles PFAS-rich membrane reject back to the reactor, improving destruction efficiency while lowering energy and clogging burdens.
- 222 nm UV PFAS Destruction with Alkaline Photochemical Treatment
This case combines 222 nm UV irradiation, sulfite salts, and alkaline conditions to break PFAS carbon-fluorine bonds.
- 222 nm UV PFAS Destruction with Sulfite in Aqueous Solutions
This aqueous treatment combines 222 nm UV, sulfite, and alkaline conditions to address inefficient PFAS destruction.
- Acid Clarification Treatment for OTSG Blowdown
Acid Clarification Treatment removes Total Organic Carbon from steam generator blowdown, preventing fouling in Once-Through Steam Generators.
- Heated Silicate Cartridge for Water Corrosion Protection
Heating solid phosphate or silicate granules increases solubility, eliminating complex dosing pumps while preventing corrosion and scale formation.
- Compact Water Treatment Device with Baffle Settling Structure
A compact water treatment device integrates turbulent mixing and baffle-configured settling channels within a single tank to separate particles efficiently.
- Eutectic Freeze Crystallization for Scale Control in Aqueous Solutions
Eutectic freeze crystallization removes scale-forming components via seed crystal treatment, preventing membrane clogging during compound recovery.
- Inorganic Salt Ion Addition for Water System Scaling Reduction
Phosphate or fluoride ion addition precipitates calcium to alleviate scaling stress, improving heat exchange efficiency while lowering antiscalant dosage.
- Lime Slurry Viscosity Control via Polyacrylate Dispersant
Adding heat-stable polyacrylate before slaking lowers viscosity and scaling, cutting lime usage by 25% while maintaining high solids content.
- Water-Soluble Imidazolines for Ferrous Metal Corrosion Inhibition
Water-soluble substituted imidazolines replace toxic heavy metal inhibitors to achieve effective corrosion protection at low dosages without environmental harm.
- Produced Water Softening via Brine Recycling and pH Adjustment
Recycles evaporator brine to precipitate calcium carbonate, eliminating scaling in SAGD heat exchangers and reducing acid costs.
- Calcium Hypochlorite Stabilization with Zinc and Magnesium Sulfate
Composite formulations using zinc salts and magnesium sulfate stabilize calcium hypochlorite, preventing chlorine loss during storage.
- ASP Oil Recovery Precipitate Dispersion
Pretreating alkaline ASP injection fluids with dispersants keeps calcium carbonate and magnesium hydroxide particles dispersed, preventing reservoir blockages.
- Cerium Dioxide Arsenic Oxidation for Water Treatment
Cerium dioxide oxidizes arsenite to arsenate, enabling alumina precipitation to reduce concentrations below 2.0 ppb.
