Ion-Exchange Resin and Reverse Osmosis Membranes

Filchem have established a relationship with Lanxess Liquid Purification Technologies (LPT), as Australian distributor for their Ion Exchange Resins and Reverse Osmosis membranes.

Lanxess’ Lewatit® range of Ion Exchange Resins are well known for their high quality and superior performance over the past 75+ years. Filchem can now offer the full range of Lewatit resins from a standard softening resin, demineralisation resins, mixed bed, a range of Cation and Anion grades, and specialty and selective chelating resins for various applications.

Lanxess’ Lewabrane Reverse Osmosis membranes are manufactured in a state-of-the-art facility built in Germany in 2015.

Providing 4” and 8” membranes in standard 40” lengths and able to retrofit existing equipment, the superior membrane chemistry and manufacturing quality provides one of the highest performing products on the market.

Both brackish and desalination membranes are available in a variety of grades such as Low Energy, High Flux, and Fouling Resistant. Recently a new ASD “Alternative Strand Design” option for the 8” brackish water membrane was released which further reduces fouling and pressure drop to improve performance and life, and reduce the cost of operation.

Lanxess are one of the largest global manufacturers of ion exchange resins and reverse osmosis membranes and as such their technical support and expertise is second to none. you will be well supported by their LewaPlus software and global technical support, including in Australia.

Filchem in conjunction with Lanxess LPT can supply extensive system performance, design, and projection information for your requirements.
