Ion exchange resins – Small beads take on big tasks

LANXESS at Sustainabilitylive! 2011, May 24 to 26,
Birmingham, Hall 3A, Stand K26

 

As part of Sustainabilitylive! 2011, specialty chemicals company LANXESS is presenting ion exchange resins from its proven Lewatit range at IWEX in Birmingham, United Kingdom, from May 24 to 26. The focus is on technologies for treating drinking, ultrapure and wastewater, as well as water for the nuclear power plant industry.

 

The mixed event Sustainabilitylive!, which takes place every four years, combines Great Britain’s five leading environmental exhibitions: BEX (Brownfield Expo), ET (Environmental Technology), NEMEX (National Energy Management Exhibition), SB (Sustainable Business) and IWEX (Industrial Water Expo). “We are introducing our high-performance products and comprehensive services here because in terms of industrial expertise and innovation, it’s the most important exhibition and congress event across the United Kingdom in the fields of the environment, energy, water, sustainability and remediation. We reach a broad public here from all of western Europe,” says Jean-Marc Vesselle, head of the Ion Exchange Resins (ION) business unit. “In this age of global water problems, operators of municipal water treatment plants, environmental associations and original equipment manufacturers (OEM) are searching here for innovative solutions, and the demand was never greater than it is today,” adds Vesselle.

 

“Even supposedly familiar, proven systems are not always operated at ideal levels as far as chemical use and water consumption are concerned. We advise our customers extensively on how to achieve optimal efficiency with our products and technologies,” says Stefan Hilger, global head of Industrial Water Treatment segment at ION.

For example, depending on the process, heterodisperse ion exchange resins can be replaced by monodisperse grades from the Lewatit MonoPlus family. These beads offer high chemical, mechanical and osmotic stability as a result of their optimized particle size distribution, with a uniformity coefficient significantly below 1.1. These properties have a positive effect on the operating capacity and service life of the resins. With Lewatit MonoPlus, the critical parameters for plant operators such as reduced wastewater and energy consumption, as well as decreased operating costs resulting from the use of less chemicals. Further, investment costs for new facilities can be reduced by smaller tank geometries and optimized resin volumes.

 

LANXESS is one of few suppliers worldwide that can also provide special, chelating ion exchange resins in monodisperse grades for many other water treatment processes. These resins include products from the tried and tested Lewatit MonoPlus TP line, which are used, for example, to remove heavy metals in process water treatment.
