The acquisition, which includes Rochem and Sepro membranes, elements and modules, follows Ultura’s bankruptcy filing last year.
 
Ultura was launched in early 2014, bringing together three established names in the membrane business - Rochem, Sepro and APTwater. The Ultura product portfolio will now be re-branded with the Nanostone Water mark.
 
Headquartered in Eden Prairie, Minnesota, Nanostone Water has ceramic membrane manufacturing operations in Halberstadt, Germany. The company is currently piloting a high surface area monolith membrane which is expected to be released later this year. The acquisition of Ultura’s membrane business expands Nanostone Water’s product portfolio adding polymeric MF/UF/NF and RO technologies while extending its manufacturing base to Oceanside and Carlsbad, California.
 
David Jellison, Nanostone Water’s CEO, said: “The acquisition aligns our company with a powerful combination of ceramic and polymeric membrane technologies. We expect our ceramic monolith technology to be truly game-changing, while the newly acquired polymeric membrane portfolio is widely recognized for high performance in a variety of industrial process and water treatment applications. Together, the combination of ceramic and polymeric technologies will offer our customers a differentiated, high level of membrane separations efficiency and effectiveness in a variety of applications.”
 
Nanostone Water is a portfolio company of True North Venture Partners, a Chicago-based venture capital firm.
