Membranes TRIZ Cases
- Monolithic Microfiltration Container for Residue-Free Sterile Drainage
An integrated monolithic base with built-in valves and probe ports removes stagnation zones and supports sterile, residue-free fluid emptying.
- Flared-End Membrane Vessel Sealing for Low-Pressure Leak Control
A flared tube end, inclined cap surface, clamp, and o-ring create a secure low-pressure membrane vessel seal that minimizes leaks.
- R2R Reduced Graphene Oxide Membranes for Alkali-Stable Nanofiltration
An aqueous roll-to-roll vacuum filtration process makes defect-free rGO membranes that withstand kraft black liquor and reject over 98% lignin.
- Zeolite Membrane Separation of Azeotropic Fluorocarbon Gases
Zeolite pores separate fluorocarbon gases by molecular size, cutting distillation energy use and overcoming azeotrope limits in gas recovery.
- Mycelium Fiber Filtration for Heavy Metal and Hydrocarbon Removal
Plant-fiber filters inoculated with fungi combine physical filtration and bioremediation to remove heavy metals, hydrocarbons, and microbes from fluids.
- CO2 Pump Membrane Using Moisture Swing for Continuous Air Capture
A moisture-swing membrane uses water and carbon concentration gradients to continuously capture and pump CO2 with no moving parts.
- Bipolar Membrane Electrodialysis for Regenerating CO2 Capture Solution
A BPMED and carbonate separation scheme regenerates hydroxide capture solution for dilute-air CO2 capture with lower energy use and more flexible operation.
- Filter Container Sealing and Release With a Separate Fixing Tool
A separate fixing tool keeps the filter container airtight against an elastic seal while allowing low-force removal to reduce contamination.
- Beverage Filtration Using Split Pasteurization and Microfiltration
Separating juice into solids and liquid enables solids pasteurization and cold microfiltration to cut microbes while preserving flavor and nutrients.
- Juice Filtration by Fractionated Pasteurization and Microfiltration
Cross-flow ultrafiltration splits juice so only solids are heat treated, reducing microbes while preserving fresh flavor, nutrients, and shelf stability.
- Asymmetric Hollow Fiber Membrane Structure for Anti-Clogging Plasmapheresis
A gradient pore structure in a polyethersulfone hollow fiber membrane reduces clogging, lowers transmembrane pressure, and stabilizes plasma separation.
- Crosslinked Graphene Oxide Membranes That Resist Water Delamination
Crosslinking graphene oxide with aldehyde-modified cellulose preserves water permeance while improving adhesion, abrasion resistance, and wet stability.
- Protein Mixing with a 10-Inch Impeller Under Shear Limits
A 10-inch impeller achieves homogeneous etanercept mixing while keeping shear stress below 125,000 s⁻¹ and avoiding impeller change downtime.
- Used Oil Membrane Separation to Prevent Fouling in Re-Refining
Low-temperature membrane separation re-refines used oil while avoiding distillation fouling, caustic treatment, and maintenance downtime.
- Amorphous Silica Membrane Separation of Azeotropic Fluorocarbon Gases
A sol-gel amorphous silica membrane separates fluorocarbons by molecular size, reducing distillation energy and overcoming azeotropy.
