FilmTec Corporation was a US company established in Minnesota in 1977 that specialized in manufacturing the then new thin-film composite membranes used in water treatment applications.[1] In August 1984, the company was acquired by Dow Chemical Company forming its Dow Water & Process Solutions business unit, which is currently among the world's main membrane manufacturers.

The unit has two large resellers, Siemens and the RO Group, both of which also sell products from competitors including Hydranautics and GE.
