LG RO Elements

LG Water Solutions, now transitioning its water business identity toward NanoH2O, is known for RO elements built around thin-film nanocomposite membrane technology.The brand is influential in desalination and industrial membrane selection because it emphasizes higher flux, salt rejection, and energy efficiency at the element level, especially for brackish-water and seawater duties.

LG / NanoH2O RO Elements's position in RO/NF membranes and related equipment is defined by product families such as Principles of Thin-Film Nanocomposite Membranes.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 LG BW 400 AFR G2, LG BW 400 R G2 and LG BW 440 R G2.Engineers should compare element size, salt rejection, permeate flow, pressure rating, fouling resistance, connection type, and vessel fit.

How to choose LG RO Elements RO Membranes

This section answers two questions: which main product families LG RO Elements 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 Principles of Thin-Film Nanocomposite Membranes. 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.
