LANXESS tackles the water challenges in China

LANXESS at Aquatech China 2015</br> June 10-12, 2.014, Hall 7, Shanghai National Convention Center

  • Expanded Lewabrane® seawater RO product portfolio
  • Lewatit® MonoPlus TP 260: a new approach for selective fluoride removal
  • First University Students Research Competition
  • Update LewaPlus ™ design software

June 1, 2015, Shanghai - Specialty chemicals group LANXESS will bring its full range of water treatment solutions to Aquatech China 2015, to be held from June 10 to June 12 in Shanghai. At China's largest international water show, LANXESS’ Liquid Purification Technologies business unit will present Lewatit® ion exchange resins and Lewabrane® reverse osmosis (RO) membranes, alongside the LewaPlus™ design software. Products on show will include Lewatit® MonoPlus TP 260 for selective fluoride removal and Lewabrane® high flow type of seawater membrane.

LANXESS will also kick off its first University Students Research Competition themed under “Clean Water for Better Life” on the first day of the show. Through the competition, students from five universities will research into the challenges faced with the middle and lower reaches of Yangtze River and propose solutions with the guidance from LANXESS water experts.  

“The goal of the competition is to raise the crucial awareness of water issues in China among our young people and motivate them to tackle these challenges in the future,” said Ming Cheng Chien, CEO of LANXESS Greater China. “As a water treatment solution provider and a responsible corporate citizen, LANXESS is committed to supporting China for achieving not only better air, but also cleaner and safer water.”

The water scarcity and pollution challenges in China have attracted rising attention in light of increasing public awareness towards environment protection and sustainable development. In response, China announced its Water Pollution Prevention & Control Action Plan (Water Action Plan) in April, which imposes strict supervision and rigid punishment systems against violations in waste water treatment and discharge. The plan also encourages water recycling by limiting the water consumption in the industrial sector.

“While China is enhancing management on waste water treatment and discharge operations, China’s water treatment market is open to huge opportunities,” said Rita Dicke, Vice President for Liquid Purification Technologies Business Unit in Asia-Pacific. “LANXESS water treatment solutions such as ion exchange resins and reverse osmosis membranes are specifically suited for processing the industrial effluents, especially from the focused industries outlined by the Water Action Plan including the textile, electroplate, power generation, chemical engineering, etc..”

LANXESS is one of the few companies that offer both ion exchange resins and reverse osmosis membrane elements – two different yet complementary water treatment technologies, thus helping it provide complete solutions to the water challenges in China including wastewater treatment, water reclamation and seawater desalination.

Lewatit® for wastewater treatment
Water treatment with Lewatit® ion exchange resins helps to isolate and selectively remove dissolved particles from liquids. They can be used for the removal of toxic substances from industrial waste water, as well as from groundwater.

Among the highlights on show, Lewatit® MonoPlus TP 260 is a weakly acidic, macroporous cation exchange resin with chelating amino methyl phosphonic acid groups in a special form for the selective removal of fluoride. The monodisperse beads are mechanically and osmotically more stable. The optimized kinetics lead to an increased operating capacity compared to ion exchange resins with heterodisperse bead size distribution.

Lewatit® MonoPlus TP 260 provides a new approach for selective fluoride removal from wastewater as well as ground and potable water based on a one-stop process.      

Expanded seawater membrane offering
On top of the Lewabrane® RO S HR (high rejection) type launched last year, LANXESS further expands its seawater membrane offerings by introducing the High Flow (HF) type.  Lewabrane® RO S HF type features high flow productivity, low salt passage at high fluxes and low energy demand. This series is also available in three different sizes: RO S400 and RO S440 have a standard length of 40 inches (1,016 mm) and a diameter of 8 inches (201 mm) suitable for use with¬in standard RO membrane equipment. The third new type, Lewabrane® RO S085 4040, is a 4-inch (101 mm) RO element suitable for smaller applications.

The Lewabrane® RO S HR (high rejection) type is designed for single pass seawater desalination plants where a high rejection is necessary. The Lewabrane® RO S HF type was developed to treat water from the Atlantic and Pacific oceans or for double pass desalination plants. Both types can be installed in one pressure vessel as a hybrid system to improve rejection and energy demand.

For water treatment in China
LANXESS Lewatit® ion exchange resins have already found applications in around 150 power plants in China, helping at numerous points to ensure the efficient, safe and reliable operation of these power plants over many years. For example, LANXESS supplied Lewatit® Monoplus S108H and Lewatit® Monoplus M800 to China Guodian Corporation’s power plant in Hanchuan, Hubei Province, which has a power capacity of 2000MW. These ion exchange resins are essential for the demineralization of the cooling and make-up water and for condensate polishing in the water-steam circuits. They are the only means of preventing scale formation and thus promoting optimal heat transfer on a continuous basis and effectively reducing or even preventing corrosion. These effects, together with the high regenerability of the resins, ensure long-term, economical power plant operation.

LANXESS’ RO elements are also operating in different industries in China including dyeing, pharmaceutical, chemical, semiconductor industries as well as power plants. The chemistry approach for our RO membrane places the emphasis on higher cross-linking of the polyamide layer and, therefore, higher durability, more stable rejection of mixed ion salt solutions and lower surface charge on the membrane to reduce the fouling tendency.

Design Software LewaPlus ™
LewaPlus ™ is an advanced  engineering tool to design water treatment systems using ion exchange resins and reverse osmosis. It is the only software application that can design an entire reverse osmosis process with downstream ion exchange, including post-treatment applications involving a degasification system or chemical addition. The software can design more than 10,000 possible configuration and offers a post-treatment and a cost-energy calcu¬lation tool. In order to support the constant high rejection of Silica with Lewabrane®, LANXESS has extended the modules to implement the pH dependency of the Silica rejection. Besides, an additional screen is added to the RO design to increase user friendliness by providing an detailed overview about the whole RO system.

The tool is available in 11 languages, including Chinese. For more information, please access to

Clean Water for Better Life
The University Students Research Competition, jointly organized by LANXESS and China WTO Tribune, will collect water research proposals from Wuhan University, Hohai University, Jiang’nan University, Tongji University and East China University of Science and Technology. Up to 10 project proposals will be singled out and get funded for further research while LANXESS experts will provide technical support and consultation. The competition will enter the final stage in September, when the 10 projects will be evaluated according to various dimensions. The awarding ceremony is planned in October to reward the winning teams.
