Food Processing and Packaging Company Tetra Pak has acquired Minneapolis-based Filtration Engineering Company, Inc., a U.S. leader in membrane filtration technology for the dairy and cheese industries.

Filtration Engineering, a privately held company established in 1982, specializes in the design, construction and commissioning of membrane filtration systems used in the areas of milk, whey and specialized waste treatment systems. The company employs 39 people.

The acquisition, for an undisclosed sum, combines Filtration Engineering’s expertise in spiral membrane technology with Tetra Pak’s existing ceramic membrane systems portfolio, expanding Tetra Pak’s portfolio of system and application knowledge for dairy, cheese and whey processing applications.

Over the past 10 years, Filtration Engineering has collaborated with Tetra Pak on a number of projects in the U.S. According to the terms of the agreement, Filtration Engineering will remain in its current location in Champlin, Minn. and form a unit of Tetra Pak Cheese and Powder Systems Inc. Existing sales channels outside the U.S. will be maintained in a number of markets, with further global coverage through Tetra Pak market operations.
