The world population is projected to increase by one-third, to 9 billion by 2050. By 2030, 61% of the world’s population is projected to live in cities, with the vast majority of that urban growth taking place in developing countries. These estimates, along with the aging infrastructures in mature economies and issues around climate change, present major challenges for water systems throughout the world.
Dow is committed to advancing the science of water purification and lowering the delivered cost of water to meet the challenges we face today, and in the future. Our research teams develop new processes that enable lower-cost service of key application areas such as seawater desalination, water re-use, ultra-pure water generation, mining mineral recovery, and specialty separations.
The technologies we are advancing include:
- Reverse osmosis
- Ion exchange
- Ultrafiltration
- Liquid membranes
- Arsenic removal
BREAKTHROUGH INNOVATION
- Dow’s advanced FILMTEC™ membrane technology is at the heart of Western Australia’s largest seawater desalination plant. The newly-commissioned Perth Seawater Desalination Plant, currently the largest in the Southern Hemisphere, significantly improves the availability of drinking water for more than 200,000 Perth residents. The Perth plant shows that desalination can be an effective and affordable option for producing water in water-stressed regions, as well as in municipalities looking to diversify their water supply sources.
- Dow’s Terneuzen site in The Netherlands, reuses treated household wastewater twice at its production plant – once to produce high pressure steam and then again as recycled water in its cooling tower. This is the first time municipal wastewater is being reused on such a large scale within the industry. Reuse of the water exceeds 2.6 million gallons per day and is the result of collaboration between Dow, water treatment provider Evides and the Zeeuws-Vlaanderen Water Board.
