Emphasis on combining technologies for optimum results
“Innovative solutions for water treatment are increasingly requiring the pairing of two or more proven technologies. LANXESS can make valuable contributions to this in all application areas,” emphasizes Firuza Mir, Head of the Americas and Asia-Pacific regions for the Liquid Purification Technologies (LPT) business unit at LANXESS.
LANXESS’ LPT business unit will present its comprehensive range of products and services relating to process water, drinking water and wastewater—from ion exchange resins and iron oxide adsorbers, to the newer high performance reverse osmosis (RO) membranes and ultrafiltration options—at Booth #301 of the upcoming 2019 International Water Conference, November 10 – 14 in Orlando.
Expanded Membrane Offerings
Earlier this year, LANXESS introduced its HP (high performance) 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.
Ultrafiltration (UF) Membranes
Another newer addition to the LANXES product family are ultrafiltration (UF) membranes…available in North America through an agreement with the French company Polymem SA.
The innovative Gigamem UF modules reduce the operational costs and the footprint required for ultrafiltration---which, with lesser technologies-- is a limiting factor for using UF. Additionally, the permanent hydrophilic Neophil membrane material lowers the fouling tendency and ensures a stable filtration process. The Gigamem concept features a housing that is permanently fixed in place and which uses exchangeable membrane cartridges. If a fiber is damaged, the user can decide to fix the hollow fiber or to exchange the individual cartridge. This makes maintenance very easy to perform and the process very reliable.
LewaPlus System Design Software
LANXESS’ LewaPlus software--a free, comprehensive platform for designing water treatment systems with ion exchange resin (IX) and reverse osmosis (RO) membrane systems--gives users the ability to drag and drop different technologies in one design. In addition, LewaPlus offers users an intuitive cross reference tool to identify which LANXESS products work bests for each customer’s situation.
The LewaPlus Closed-Circuit Reverse Osmosis (CCRO) module helps RO system designers evaluate high recovery RO processes, often used for zero liquid discharge or minimal liquid discharge treatment processes. The CCRO process enables increased RO system recovery of up to 98% (vs. 75 to 85% for conventional RO process), lower power consumption per unit of permeate water, improved scaling control and simplified design and operation.
