January 2018


MICRODYN-NADIR, the water treatment business unit of global filtration leader MANN+HUMMEL, announces the acquisition of OLTREMARE, a leading European manufacturer of spiral-wound membrane elements.


OLTREMARE, based in Fano, Italy, is known for both the production of custom and private-label spiral products and the distribution of (RO) reverse osmosis, (NF) nano filtration membrane, ion exchange and other products used for water treatment and purification.

Along with the acquisition of TriSep Corporation in November 2016, the addition of OLTREMARE expands MICRODYN-NADIR’s capability to provide customized products and solutions. MICRODYN-NADIR serves companies treating water and wastewater as well as companies focusing on a wide variety of process applications such as dairy, food and beverage. The company offers a wide range of membrane products, including (RO) reverse osmosis, (NF) nanofiltration, (UF) ultrafiltration, (MF) microfiltration and ( MBR )membrane bioreactors.


This strategic purchase is a continuation of MICRODYN-NADIR’s commitment to service both the Water & Wastewater and Process & Specialties application segments, said Walter Lamparter, CEO of MICRODYN-NADIR. Adding OLTREMARE to our team increases our ability to service our customers around the world and continues to accelerate our growth in the water treatment & waste water treatment business.


The transaction is expected to be completed by the end of January. The parties have agreed not to disclose the purchase price.
