The CSM model system takes RE (Reverse Osmosis Element) as the brackish water mainstay and NE for nanofiltration. Suffixes distinguish positioning: -BE is the standard type (99.7%), -BLR/-BLN are low energy and medium rejection, -BLF is fouling resistant, -UL is ultra-low pressure, -FEn/-FLR are the high rejection and low fouling versions, and -CE is the low-rejection economy model.
CSM has two distinguishing features. First, it offers 16-inch elements (RE16040, about 1600 ft² per element), suited to large systems for reducing the number of pressure vessels. Second, its nanofiltration range includes the NE8040 series, divided into several models by rejection and flux.
Note: the element library on this site does not currently include CSM seawater elements; for seawater projects refer to the manufacturer's latest datasheet.

How to select
- Conventional brackish water: RE8040-BE, 99.7% rejection, balanced parameters, wide replacement coverage.
- Nanofiltration salt separation or softening: NE8040 series; choose the specific model by the required removal of divalent ions and organics.
- Large systems: RE16040 series, about 1600 ft² per element, which markedly reduces the number of pressure vessels and piping runs.
- High fouling load: RE8040-BLF (99.5%, fouling-resistant design).
CSM's official design tool is CSM Pro. Note that CSM project files have no public portable format; migrating to another software requires re-entering the water quality and array. This site includes 89 CSM elements that can be modelled directly.

FAQ
Which country is CSM's reverse osmosis membrane from?
CSM of South Korea, one of the earlier membrane manufacturers in Korea; products cover brackish water and nanofiltration.
What is the difference between the NE and RE series?
RE is a reverse osmosis membrane with high rejection (usually above 99%); NE is a nanofiltration membrane that selectively removes divalent ions and organics while allowing part of the monovalent ions to pass.
Does CSM offer 16-inch membrane elements?
Yes, the RE16040 series has about 1600 ft² per element and suits large systems by reducing the number of pressure vessels and piping runs.
How are CSM membrane parameters imported into other design software?
CSM has no public portable project file format; water quality, array and element parameters usually have to be entered manually, or the 89 CSM elements built into this site can be used directly.
