International brand dossier
Membranium
Membranium is the membrane trademark of JSC RM Nanotech, described publicly as a Russian producer of nanostructured membrane flat sheet and membrane elements for RO, NF, and UF.It is relevant where engineers compare regional membrane supply, brackish and seawater RO, NF/UF elements, and domestic manufacturing claims.
Membranium's position in RO/NF membranes and related equipment is defined by product families such as Reverse Osmose Membrane Elements for Brackish Water, Reverse Osmose Membrane Elements for Seawater, Nanofiltration Membrane Elements for Brackish Water and Ultrafiltration Membrane Elements for Ground and Artesian Water.
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 K 4040-C, K 8040-C and KC 4040-C.

Product range and selection
How to choose Membranium RO Membranes
This section answers two questions: which main product families Membranium 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 Reverse Osmose Membrane Elements for Brackish Water, Reverse Osmose Membrane Elements for Seawater, Nanofiltration Membrane Elements for Brackish Water, and Ultrafiltration Membrane Elements for Ground and Artesian Water. 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.
