LewaBrane Membranes

LANXESS Liquid Purification Technologies is a major purification-materials platform built around Lewatit ion exchange resins and related products for water treatment, ultrapure water, energy, semiconductor, food, chemical, mining, and metallurgical applications.

LewaBrane membrane records should be read in that broader liquid-purification context.LewaBrane Membranes's position in RO/NF membranes and related equipment is defined by product families such as RO, NF, UF-adjacent membrane elements, membrane contactors, pressure vessels, housings, and related separation products.

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 LewaBrane RO B370 HR, LewaBrane RO B400 HR and LewaBrane RO B440 HR.

How to choose LewaBrane RO Membranes

This section answers two questions: which main product families LewaBrane 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 General Products. 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.
