Leverkusen – Lewatit is one of the leading brands of ion exchange
resins. At Aquatech 2008 from September 30 to October 3 in
Amsterdam, specialty chemicals group LANXESS will present its highperformance ion exchange resins in combination with a comprehensive
range of services. The company will be exhibiting in collaboration with
Caldic NV, its local distribution partner for the Benelux region.
The range of exchange resins, adsorbers and functional polymers is
divided into three main areas – water, foodstuffs and
catalysis/biotechnology/chemical processes – in line with the relevant
customer applications. LANXESS will be showcasing new and
established products from the Lewatit portfolio for all these segments in
Amsterdam.
In the production of drinking water, the focus is increasingly on the
removal of toxic trace impurities, particularly arsenic. LANXESS has
now developed a product that can reliably remove this toxic metalloid
from drinking water: Lewatit FO36 is an innovative hybrid adsorber
consisting of a combination of a polymeric anion exchange resin and
iron oxide with goethite structure. The iron oxide is distributed in the
pores of the weakly basic ion exchange resin in a layer a few
nanometers thick by a special production process. This fine, highly
reactive iron oxide layer can selectively adsorb the arsenic. Because,
unlike the other anionic components of water such as chloride, nitrate,
sulfate and carbonate, only arsenic has this high affinity to the iron oxide
surface, and is thus the only substance to be adsorbed. The other
mineral components – some of them valuable – remain in the drinking
water.
Products in the Lewatit MonoPlus range are suitable for almost all water
treatment processes. Because of their monodisperse properties and
modified polymer structure, the gel or macroporous styrenedivinylbenzene copolymers have numerous advantages over traditional
heterodisperse exchangers. Each resin has an optimized and uniform
bead size, varying between 0.55 and 0.75 millimeters depending on
grade. These resins are also characterized by high chemical,
mechanical and osmotic stability, which has a positive impact on their
operating capacity and service life. The cost savings resulting from the
higher operating capacity, lower chemical and energy requirements and
reduction in wastewater when using Lewatit MonoPlus are key
parameters for operators. Moreover, the cost of investment in new units
is cut by reducing container dimensions and optimizing resin volumes.
The threshold for nickel in drinking water has been reduced from 50 to
20 micrograms per liter because of its carcinogenic effect and
sensitization. Lewatit MonoPlus TP 207 can be used to remove
substances such as nickel from drinking water. Lewatit TP resins belong
to the family of established chelating resins with applications including
the removal of heavy metals in process water treatment.
A key application of Lewatit is in the production of water that does not
cause encrustation or corrosion in nuclear power plants. In this
application, ion exchange resins need to be able to withstand large
volumes of water and countless regeneration cycles with ease. Power
plant planners and operators the world over therefore rely on the high
performance of the exchange resins developed by LANXESS for such
applications. The premium products ensure that valuable power units,
turbines, steam generators and pipelines enjoy a longer service life and
can be operated cost-effectively. Applications include complete
desalination in freshwater treatment, treatment of radioactive
wastewater in the primary circuit and treatment of cooling water or
condensation in the secondary circuit of power plants.
Ultra-pure water is mainly used in the electronics industry for the
manufacture of semiconductors and microchips, and in the
pharmaceuticals industry. Water quality requirements for residual

conductivity and TOC emissions are so high that only specially purified
ion exchange resins are used. With Lewatit UltraPure, LANXESS has
developed high-performance resins for the tough demands of polishing
circuits.
Detailed information about the company’s ion exchange resin portfolio is
available on the Internet at www.lewatit.com.
The Ion Exchange Resins business unit belongs to the Performance
Chemicals segment, which achieved total sales in fiscal 2007 of EUR
1,970 million.
