SIWW: LANXESS showcases innovative and enhanced technologies for water treatment

Specialty chemicals company LANXESS is showcasing its process, technology leadership, and innovations in water treatment and purification at this year’s Singapore International Water Week (SIWW) exhibition from 9th to 11th July.

At this biennial event, LANXESS is exhibiting its latest technologies in combined reverse osmosis (RO) and ion exchange (IX) processes that offer a wide range of solutions to treat water to the desired standard. In addition, LANXESS is debuting, for the first time in Singapore, its new Lewabrane Ultra Low Pressure (ULP) RO elements, an expansion of its extensive range of membrane elements for reverse osmosis. Recognising the importance of user-friendly technology, LANXESS has also released a new 2.0 version LewaPlus software for designing water treatment systems, which it will be showcasing at SIWW this year.


Innovative solutions to combat water scarcity

Global warming, droughts, water pollution and erratic climate change have led to rising attention on the issue of water scarcity globally. As water is becoming an increasingly valuable resource, innovative technologies need to surface to optimise wastewater treatment, and use water efficiently. Through combining two different water treatment technologies – ion exchange (IX) and reverse osmosis (RO), LANXESS provides complete solutions to the water challenges in many countries such as wastewater treatment, water reclamation and seawater desalination.


There are numerous examples from the municipal and industrial sector show how ion exchange resins (IX) and reverse osmosis (RO) membranes complement one another to achieve optimal results in water treatment. Especially for minimal liquid discharge processes (MLD) combined solutions are necessary to find a tailor-made approach to reuse or recycle water in processes. In such cases IX can be used as pre-treatment to remove hardness or organics to increase the production yield of the following RO process, or IX can be used to polish the RO permeate to up to ultrapure water quality.


Range of services for water treatment further expanded by ultrafiltration (UF)

LANXESS adds ultrafiltration (UF) to the existing range of water-treatment technologies through a cooperation agreement with the French company Polymem SA, Toulouse. LANXESS will commence worldwide distribution of the Gigamem ultrafiltration modules range from Polymem featuring Neophil hollow fiber membranes.

“We are gaining a product portfolio that ideally complements our ion exchange resins and reverse osmosis membrane elements for water treatment,” said Jean-Marc Vesselle, Head of LANXESS’s BU Liquid Purification Technologies. Ultrafiltration will soon be integrated as a new module in LANXESS’s LewaPlus design software. “After all, around one third of all newly built reverse osmosis plants have upstream ultrafiltration – and the trend is rising. This results in valuable synergy effects.”


Improving User Experience

LANXESS has made further enhancements to its LewaPlus software, which is a free, comprehensive platform for designing water treatment systems with ion exchange resin (IX) and reverse osmosis (RO) membrane systems.

This enhanced software has a high degree of design flexibility, which will allow users to have the ability to combine per drag and drop different technologies in one design and show all selected modules in a combined PDF report. In addition, the new product finder function will allow LewaPlus 2.0 users to identify which Lewatit and Lewabrane quality products they can use to replace the conventional elements to upgrade their plans.

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. Visitors to SIWW 2018 can experience the more user-friendly version LewaPlus 2.0 in action.


Eliminating trace elements cost-efficiently at low operating pressures

LANXESS also expanded its portfolio of Lewabrane RO membrane elements by ultra-low pressure (ULP) types. The product designation “ULP” stands for “Ultra Low Pressure,” because the advantage of these membranes is their ability to remove such organic compounds almost entirely even at low operating pressures. 

The new ULP products are recommended for applications in which a high flow rate, moderate salt rejection and low power consumption are the primary design parameters. Fields of application therefore are the cost-efficient filtration of drinking water and high-tech wastewater treatment.


Commitment to maintaining product quality and reliability

All products are compliant with German standards certified by international organisations to showcase LANXESS’ commitment in ensuring product safety, quality and reliability for all users and the environment. 

“Complemented by comprehensive customer service and technical support, we help our customers handle our products in a safe and environmentally responsible way, and at the same time also require our suppliers and service providers to demonstrate a similar sense of responsibility, so as to cultivate trust with our customers through an open and respectful communication,” said Tony Yang, Vice President of APAC, Liquid Purification Technologies business unit, LANXESS, “The increasing complexity, digitisation and continual change often results in challenges such as quality control. We place considerable emphasis on ensuring that our products meet the highest German and international production and quality standards.”
