MANN+HUMMEL Water & Fluid Solutions (previously MICRODYN-NADIR) is a membrane manufacturer that delivers the membrane products to meet all of your water and process needs. We offer the widest range of membrane products, including MF, UF, NF, and RO in flat sheet, spiral-wound, and hollow-fiber configurations as well as MBR technology for treatment of water and wastewater.
For over 50 years, MANN+HUMMEL Water & Fluid Solutions (WFS) has been producing high-quality membrane products for use in industries across the globe.
Originally founded in 1966 as NADIR Filtration, our company became known as a technology leader in micro-, ultra- and nanofiltration. In 2003, NADIR Filtration and MICRODYN Modulbau merged to become MICRODYN-NADIR. Then in 2021 we changed our name to MANN+HUMMEL Water & Fluid Solutions, and our impact in the membrane industry continues to grow.
Headquartered in Wiesbaden, Germany, MANN+HUMMEL WFS’s footprint reaches to all corners of the globe. In 2006, MANN+HUMMEL WFS expanded to Asia with the founding of MICRODYN-NADIR China in Xiamen. Later, this was merged with other locations in China and relocated to Kunshan.
Since February 2015, MANN+HUMMEL WFS has operated as the water unit of global filtration titan MANN+HUMMEL. This partnership saw the addition of Ultra Flo Pte. (acquired in 2010 and renamed MICRODYN-NADIR Singapore, now merged with another MANN+HUMMEL Singapore location).
In 2016, MANN+HUMMEL WFS acquired TriSep Corporation, the membrane industry’s leader for specialty and custom membrane solutions. Originally founded by Peter Knappe and James Bartlett in 1989, TriSep Corporation found immense success producing reverse osmosis and nanofiltration membranes as well as innovative sanitary spiral elements for the process and specialty industries.
2018 brought the acquisition of Oltremare SPA, the leading provider of private-labeled reverse osmosis spiral-wound elements in Europe. The company has offices in Europe, Asia, and North America with sales personnel and engineers located in dozens of countries.
