Lanxess has announced enhancements to its LewaPlus software for designing water treatment systems. With its 2.0 release, users now have the ability to combine different technologies in one design.

According to the company, users can seamlessly simulate complex plant designs including a combination of several treatment steps in a single design process. The water analysis calculated by the individual modules is automatically taken over as feed to the subsequent module. During the design process, the user can change the design of the system via drag and drop. 

With LewaPlus 2.0, calculations can be made for designs that not only treat the purified stream of water, but also the retentate. As a result, environmentally-friendly overall concepts can be calculated in order to significantly reduce the volume of wastewater produced in practice.

The modules can be added to a project via drag and drop – even retrospectively in a later stage of the process. This is helpful if the system designer decides to add pretreatment of feed during the design process, for example. 

Compared to previous versions, the software can now show all of the selected modules in a combined PDF report. A list of links to the respective modules, which can be individually renamed, helps the user to navigate through the PDF quickly and easily.

In addition, the new version offers a product finder. It enables users to identify which Lewatit and Lewabrane products they can use instead of conventional ion exchange resin types and reverse osmosis membrane elements to upgrade their plants.

LewaPlus allows the dimensioning of ion exchange- and reverse osmosis systems for a wide variety of system configurations, including several one-of-a-kind process configurations that can only be achieved with Lewatit and Lewabrane technology.

Numerous modules are available for the calculation of every step of the water treatment process. As a result, users can precisely plan important factors such as operating costs, power consumption, and water quality. One module can even be used to model a CCRO system (closed circuit reverse osmosis). This helps to enhance the ecobalance of water treatment through the use of either ZLD (zero liquid discharge) or MLD (minimal liquid discharge) treatment processes. 

The LewaPlus design software can be downloaded free of charge.
