Chemistry and technology in harmony
Many industrial processes rely on clean, pure and ultrapure water. Therefore it is extremely important that the relevant treatment plants are designed correctly, but actually doing so is far from easy. Specialty chemicals group LANXESS has decades of know-how and technical experience in this field. More than 20 years ago its Ion Exchange Resins (ION) business unit became one of the first suppliers in the market to offer a reliable planning
aid for project calculation. The program has since then been developed further and improved on a continuous basis. The new version Lewatit-CalculatION 5.0 makes designing a treatment unit even simpler. The flexible, yet straightforward program accelerates project costing and can even help existing plants cut their operating costs. The multilingual software offers further new functions and is available from LANXESS free of charge.
“It's not difficult to point out the primary challenge facing those tasked with designing water treatment plants for providing process water”, says Björn Dinges from Technical Marketing Industrial Water Treatment in the ION business unit. As one of the team involved in developing the new system, Dinges explains:
“The people responsible for planning and developing these plants generally display exceptional expertise when it comes to process engineering. Though they are less familiar with the chemical processes in the ion exchange resins that are, after all, the key process components involved.
However, if these products are viewed as a 'black box' around which the filter system simply has to be built, it could lead to wasted potential.” This is particularly true when it comes to a high level of performance, as exhibited by Lewatit ion exchange products from LANXESS, and to the increasing demands made of ultrapure and wastewater streams. Selecting an ion exchange resin
to deal with a particular problem, optimizing regeneration sequences as well as undertaking realistic assessments of wastewater volumes and their composition can all make it easier to ensure proper compliance with legal requirements.
“This is where Lewatit-CalculatION 5.0 comes into play”,continues
Dinges. “The system helps to ensure the water treatment system is perfectly adapted to the relevant process requirements.” It supports the user in carrying out detailed analyses of his actual
requirements and suggests the type and volume of the ideal Lewatit ion exchange product depending on the needs of the specific customer. “We have been careful to make sure that the software is easy to use, yet also remains flexible. It can be used for the detailed planning of a wide range of chemical processes that can be adapted to the application in question using numerous variables.
However, there is also a practical set of process parameters and limits available to help the user become acquainted with the system.” As the software is available in several different languages, it is ideally suited to users right across the globe. Additional water chemistry calculation features make it possible to accurately assess the specific silica load, predict wastewater composition and determine
