Water Contaminants TRIZ Cases
- Wastewater Incineration Heat Recovery for Lower Discharge Temperature
Segmented heat exchange recovers incinerator waste heat to preheat fresh air, cutting fuel use and lowering discharge temperature.
- Secondary Water Filter Up-Flow Layout to Prevent Media Channeling
An up-flow secondary filter with a surrounding shell prevents media channeling and fines migration, extending filter life and contaminant removal.
- Submersed Primary Water Filter to Prevent Media Channeling
A submersed primary filter and up-flow secondary stage keep media uniformly wet, reducing channeling and extending filter life.
- Layered Double Hydroxide Crystal Structure for Higher Anion Exchange
High-temperature solid-state synthesis creates uniform layered double hydroxide crystals that resist agglomeration and improve fluoride and arsenide ion exchange.
- Rare-Earth Separation Using PEI-CS2 Selective Precipitation
A PEI-CS2 salt forms a separable suspension in aqueous metal mixtures, enabling high-purity rare-earth recovery with simpler processing.
- Floating carrier for water heavy metal removal reagents and method for removing heavy metals from water
Venturi flow and microfluidic suction increase reagent contact while resisting clogging, enabling reusable heavy metal removal from water.
- Cobalt/Boron Nitride Composite for Stable Persulfate Activation
Uniformly dispersed cobalt nanoparticles on boron nitride prevent aggregation while enabling fast, reusable persulfate activation for pollutant degradation.
- Selective Ion Separation Membranes for Wastewater Resource Recovery
Voltage-driven ion exchange membranes separate target ions from wastewater, improving selectivity while recovering valuable constituents.
- Bottle Cap Filtration for Microplastic Removal at Consumption
A cap-integrated filter removes micro-plastic particulates as liquid is consumed, preserving bottle portability while improving drinking safety.
- Cu-EDTA Wastewater Reclamation via Reductive Decomplexation
Alkaline formaldehyde and copper powder generate H· radicals to split Cu-EDTA, enabling copper settling and EDTA recovery.
- Silicate Ion Removal Electrodes That Maintain pH During Adsorption
Hydroxide generation at a graphite electrode keeps silicate soluble during adsorption, raising removal efficiency beyond conventional CDI.
- Multi-Intake Pond Filtration for Gravity-Fed Water Quality Control
Multiple riser intakes, gravity-fed drum filtration, and staged biofilters keep pond water clear, oxygenated, and low-noise.
