LANXESS makes dimensioning tool for water treatment more practical

Dimensioning tool includes water library

LANXESS has comprehensively updated its LewaPlus design software for the water industry. The dimensioning of reverse osmosis (RO) and ion exchange systems (IX) is now even more practical and user-friendlier. There is also the option to include ultrafiltration (UF) in the planning. The new UF module will be presented for the first time at Aquatech, which will take place in Amsterdam.
New UF module for the design of ultrafiltration
Ultrafiltration is used as pretreatment for reverse osmosis – and increasingly for ion exchange resins applications. Around one third of all newly built reverse osmosis systems have upstream ultrafiltration – and the number is rising.
LANXESS is a global distributor of high-quality Gigamem ultrafiltration membranes and systems from French company Polymem, which is based in Toulouse. In order to design complex water treatment systems that also include ultrafiltration technology, LANXESS has now integrated this pretreatment into its software.
Ultrafiltration purifies and disinfects water in a single step. It is an alternative to conventional filtration in water purification and produces filtrate with a water quality that is considerably more consistent. Ultrafiltration often also replaces other conventional treatment techniques as well as microfiltration, as it also removes smaller particles and thus significantly reduces deposits in subsequent process steps. This enables a more stable process.
Water classification helps with system design
LewaPlus also offers users the option to create their own water library. This is because customers often have only an incomplete water analysis – if they have one at all – when planning their system. With a library, they can then utilize the data that is stored in LewaPlus. “We are planning to expand on the master data to include additional water types. There are even already parameters in place for the quality of seawater from various regions,” explains Dr. Jens Lipnizki, head of Technical Marketing Membranes in the Liquid Purification Technologies (LPT) business unit.
