MIDLAND, MI, Feb. 17, 2005 -- The Dow Chemical Company remembers John E. Cadotte, the inventor of the groundbreaking FT-30 reverse osmosis and nanofiltration chemistry, who died recently at age 80.

A member of the American Chemical Society, Cadotte's discovery of FT-30 chemistry, used in membranes for water purification, was a breakthrough in the industry and serves as the foundation for the manufacture of reverse osmosis membranes by companies such as FilmTec Corp. and other RO and NF membrane manufacturers.

Cadotte and three others founded FilmTec in 1977 and was one of the original employees when it started in 1978. Prior to that, he conducted research at Midwest Research Institute, a not-for-profit organization performing research on RO membranes under a government contract. The Dow Chemical Company acquired FilmTec in 1985 and now manufactures FilmTecTM RO membranes and nanofiltration elements based on the FT 30 membrane.
