Water Treatment Parameter Control TRIZ Cases
- Performic Acid Water Treatment System with Feedback Control
A water treatment system feeds performic acid to disinfect liquid using a dosing device and measuring apparatus.
- Potassium Cation Treatment for Zebra Mussel Control
Potassium cations interfere with bivalve oxygen transfer, preventing settlement and avoiding oxidation by-products from chlorination.
- Worm Control in Membrane Aerated Biofilm Reactors
Withholding oxygen for 3 to 48 hours eliminates nematode populations, preserving nitrifying biomass and improving effluent quality.
- Pressurized Water Mineralization Device
A pressurized container supplies mineral solubilization gas to chemically react with solid minerals, producing fully dissolved compounds in treated water.
- Biodegradation Bed Effluent Treatment System
Transparent covers facilitate evaporation while containment structures prevent environmental contamination from agricultural washing waste.
- Vacuum Tank Solids Separator for Human Waste
A vacuum tank solids separator divides human waste using a cylindrical filter, preventing pathogen contamination in off-grid sanitation systems.
- Sludge Fermentation Carbon Source for Landfill Leachate Nitrogen Removal
Sludge fermentation products supply carbon for denitrification, resolving low carbon-nitrogen ratios and reducing excess sludge volume.
- Desalination Architecture Optimization via Subsystem Modeling
A desalination architecture selection method uses coupled subsystem models to evaluate design alternatives and identify optimal configurations.
- Water Treatment System with UV Bacteria Elimination
A water treatment system uses ultraviolet light to eliminate bacteria in contaminated runoff.
- Chemical Regulation System for Pool Overflow Prevention
A chemical regulation system manages liquid flow rates and composition using automated valves and a controller.
- Portable Water Filtration for Aircraft Upload
Replaceable filter cartridges and a UV disinfection unit purify water before upload, preventing pathogen introduction from variable airport sources.
- Bioreactor Flow Control for Wastewater Stability
Segmented bioreactors with feedback control maintain constant organic loads, preventing microbial upsets during influent fluctuations.
- 8-Hydroxyquinoline Modified Halloysite Nanoclay for Brine Treatment
8-HQHNC removes heavy metals and salt from brine, addressing inadequate removal efficiency in desalination plant discharges.
- Single Reactor Wastewater Treatment for TMAH and Ammonium Nitrogen
A single reactor treats wastewater containing tetramethylammonium hydroxide and ammonium nitrogen using controlled microbial processes.
