Specific Water Treatment Objectives TRIZ Cases
- Two-Zone Large Water-Body Treatment for Lower-Cost Disinfection
Dividing a large water body into sedimentation and dissipation zones lowers treatment costs while maintaining chlorine-based sanitary protection.
- In-Situ Layered Double Hydroxide Treatment for Silica and Total Hardness
At pH above 8, magnesium hydroxide and soluble aluminate form a layered double hydroxide in situ to remove silica and reduce hardness.
- Modular UV Plate Reactors for Consistent Fluid Sterilization
Modular UV plates use controlled channel diameters and radiant flux to deliver consistent doses during fluid sterilization.
- Non-Powered Water Supply With Gravity Filtration for Turbid Water
Gravity-driven filtration and chemical disinfection help small island and mountainous water systems stabilize quality during high-turbidity conditions.
- Porous Dielectric Plasma Treatment for Wastewater Color Removal
A porous dielectric of silicon dioxide and carbon adsorbs nitrogen oxide during plasma treatment to remove wastewater color.
- Mobile Water Pipe Disinfection With Sealed Biocide Dosing
A sealed tank and dosing pump disinfect drinking water pipes while preventing operator contact with biocidal products.
- Permanganate Water Production with Ozone Microbubbles Without Precipitates
Ozone microbubbles produce stable permanganate water without organic precipitates.
- Open-Cell Foam Pathogen Capture and Disinfection
Porous foam samples large water or air volumes over time, concentrates pathogens, and supports targeted disinfectant treatment.
- Fluorous Biphasic PFAS Extraction for Short-Chain Recovery
Fluorous-functionalized supports and scCO2 concentrate and recover short-chain PFAS with less sensitivity to co-contaminants.
- Plasma-Assisted Water Treatment for Persistent Contaminant Reduction
A discharge cell uses pulsed corona or barrier plasma in reducing gas to degrade persistent water contaminants.
- Membrane Filter Cleaning by Ultrasound and Backwash Pulses
Periodic ultrasound and high-pressure backwash pulses remove surface particles, sustaining flux and extending membrane filter life.
- Liquid Treatment Device With Detachable Post-Filter And Uniform Flow
A segmented liquid treatment device separates post-filter replacement from the carbon block while distributing flow more uniformly.
- Peritoneal Dialysis Waste Disposal With Enclosed Cutting and Disinfection
An enclosed machine weighs dialysis waste, cuts drainage bags, controls liquid flow, and disinfects the chamber to limit exposure.
