Membranes TRIZ Cases
- Polyolefin Multilayer Separator for Battery Thermal Safety
A polyolefin multilayer membrane combines ultrahigh molecular weight polyethylene with high-density polyethylene and polypropylene layers.
- Solid Heat Storage Energy System for Salt Lake Lithium Extraction
Solid heat storage devices supply process hot water and vapor, reducing energy consumption by reusing waste heat in salt lake lithium extraction.
- Compact Blood Oxygenator with Integrated Heat Control
Merging the heat exchanger with the oxygenator reduces filling volume while maintaining precise temperature control for mobile extracorporeal support.
- Thin Film Composite Membrane Additives for Water Flux
Metal chelate and phosphoramide additives in the polymerization matrix increase water flux while maintaining salt rejection at lower operating pressures.
- Integrated Membrane Module for Space-Constrained Liquid Treatment
A separation membrane module houses both a degassing element and a filtration unit within a single container to reduce system footprint.
- Carbonic Acid Descaling via Reverse Osmosis Permeate
Pressurized carbon dioxide mixes with reverse osmosis permeate to create carbonic acid for in situ scale removal without hazardous waste.
- PVDF Substrate Bonding for PS PES Membranes
Heat bonding PVDF substrates to PS or PES membranes resolves skin formation and particle generation during welding.
- Polysulfone Hollow Fiber Membrane Asymmetric Hydrophilic Distribution
A polysulfone hollow fiber membrane uses asymmetric hydrophilic polymer distribution to enhance blood compatibility and module integration.
- Cu-Ni Powder Sintered Porous Metal for Hydrofluoric Acid Permeability
A powder sintered porous metal with a tortuosity factor of 1.02 to 1.25 enhances permeability and backflushing regeneration.
