International brand dossier
3M-Liqui-Cel® Membrane Contactors
3M Liqui-Cel and Liqui-Flux records should be read as 3M membrane contactor and membrane-filtration technologies.Liqui-Cel is used for dissolved gas control such as degassing and carbonation management, while Liqui-Flux UF modules support filtration duties where compact membrane modules and established 3M component supply are useful.
3M-Liqui-Cel® Membrane Contactors's position in RO/NF membranes and related equipment is defined by product families such as Debubbling, Gas transfer, Degassing (low surface tension fluids) and Application / guidance.
The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include MM Series 0.5 x 1, MM Series 0.75 x 1 and MM Series 1.7 x 5.5.Engineers should compare element size, salt rejection, permeate flow, pressure rating, fouling resistance, connection type, and vessel fit.

How to choose 3M-Liqui-Cel® Contactors Closed Circuit Reverse Osmosis
This section answers two questions: which main product families 3M-Liqui-Cel® Contactors offers, and which parameters to compare before choosing a specific model.
Step 1: Choose a product family by application
The main families shown on this page are Debubbling, Gas transfer, Degassing (low surface tension fluids), and Application / guidance. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
Step 2: Confirm the model by key parameters
After choosing a product family, compare feed salinity, target salt rejection, permeate flow, operating pressure, fouling tendency, and element size and connection. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.

Application / guidance
Transverse flow: Liquid flows into the liquid inlet, crosses the hollow fibers, and then exits through the opposite port. No baffle is used. A vacuum or strip gas can be applied to either gas port · Radial flow: A plugged center tube on one side forces liquid radially over the hollow fibers. Primarily used for degassing low surface tension fluids · Extra-flow in high pressure vessel: An RO-style vessel generates a much higher maximum pressure. Liquid is directed radially across the membrane array by a baffle
