LANXESS Showcasing Expanded Membrane Portfolio At MTC 2019 In New Orleans

MTC will be the first showing of LANXESS’ new Lewabrane HP membrane elements Innovative Gigamem UF modules also on display

LANXESS’ Liquid Purification Technologies business unit—operating in the United States as LANXESS Sybron Chemicals—will showcase its expanded portfolio of water purification membranes, including the exciting new HP and UF lines, at Booth #609 of the upcoming 2019 Membrane Technology Conference & Exposition, February 26 – 28 in New Orleans.

Introducing Lewabrane HP (high performance) Membranes
MTC 2019 will be the first opportunity for the industry to see first-hand LANXESS’ just-released HP (high performance) reverse osmosis (RO) membranes. Lewabrane RO B400 HP and Lewabrane RO B440 HP elements include enhanced brackish water processing capabilities to serve applications in which high rejection and energy efficiency are important. Using the new types in combination with monodisperse Lewatit ion exchange resins provides high quality produced water at lower operational cost.

With an average salt rejection of 99.7% (at 2,000 ppm NaCl; 15.5 bar/225 psi) and high permeability, Lewabrane HP membranes are a further development of the high cross-linked polyamide membrane which LANXESS launched in 2012. Controlling the degree of polyamide cross-linking during production process provides a small effective “pore size” that results in high rejection of solutes, regardless of their charge. “By optimization of the process, the flux could be improved without compromising permeate quality. Therefore, high rejection, even at changing feed parameters like pH or salinity, can be achieved at high flux rate,” explains Dr. Jens Lipnizki, head of Technical Marketing Membranes in the Liquid Purification Technologies business unit.

The Lewabrane reverse osmosis (RO) membrane elements product line, including the recently introduced Ultra Low Pressure line, is characterized by high water permeability resulting in low power consumption and low cost operation. These Lewabrane elements are also used for removal of CEC’s (contaminants of
