We admit we go a little overboard in our passion for perfecting water treatment.


Yachts, sail boats and commercial marinas require fresh, safe water for drinking, bathing, food preparation and other uses. To meet that need, Dow Water & Process Solutions converts sea water into usable water through desalination.

Reverse osmosis (RO) is the primary technology we use to desalinate seawater. Dow provides FILMTEC™ Seawater RO Elements that contain special membranes that offer high flow rates without sacrificing salt rejection; this allows lower pressure operation that reduces pump size and cost, as well as operating expenses.
