Contaminated Soil Reclamation TRIZ Cases
- Handheld Soil Disinfection Device with Spring-Ejected Needle
A handheld soil disinfection device uses a spring-loaded mechanism to eject a piercing needle into the ground for fumigant injection.
- In-situ Reagent Injection via Compressed Air Pre-conditioning
Compressed air injection creates uniform pore channels in aquifer media, resolving uneven diffusion and backflow issues during soil remediation.
- Bioelectrochemical System for Soil Bioremediation
A bioelectrochemical system degrades petroleum hydrocarbons in contaminated soil using microbial electron transfer.
- Porous Membrane Gas Diffusion for Groundwater Decontamination
A porous microstructured membrane enables in situ gas diffusion into groundwater for efficient decontamination.
- Dispersed Air Flotation Foam for Radioactive Soil Decontamination
Dispersed air flotation foam removes radionuclides from fine soil particles using pneumatic separation, reducing water usage and excavation needs.
- In Situ Arsenic Remediation via Stabilized Peroxide and Iron Complex
Alternating injection of stabilized peroxide and chelated iron controls gas production while oxidizing arsenic from As+3 to As+5.
- Sintered Soil Bed PFAS Removal via Thermal Desorption
Sintered soil bed mobilizes PFAS contaminants using sequential heated air waves, avoiding hazardous hydrofluoric acid gas production during remediation.
- Hydrophobic Media Release Agent for Mineral Particle Removal
Low surface tension solvents disrupt chemical bonds on hydrophobic collection media, reducing mechanical damage during mineral particle liberation.
- Funnel-and-gate wall with replaceable remedial permeable gate
Segmented impermeable side walls guide fluids to a replaceable permeable gate, resolving maintenance complexity in deep excavation sites.
- Soil Remediation System Using Heat and Vacuum
A soil remediation system applies heat and vacuum to volatilize contaminants from contaminated soil.
- Modular Mobile Soil Treatment Unit for Contaminated Sites
A modular mobile soil treatment unit integrates aeration and filtration to degrade petroleum hydrocarbons in contaminated ground.
