About Dow Water Solutions

Dow Water Solutions is part of the Designed Polymers business of The Dow Chemical Company. Dow Water Solutions is a comprehensive global provider of water and non-water treatment and separations solutions based on a wide range of advanced technologies and services:

  • FILMTEC™ reverse osmosis (RO) and nanofiltration (NF) elements. 
  • DOWEX™ ion exchange resins. 
  • ADSORBSIA™ GTO™ titanium-based arsenic removal media.
  • Zhejiang Omex Environmental Engineering Co. Ltd. (OEE)
    • Enabling component technologies for water treatment, including:
      • Ultrafiltration (UF)
      • Membrane Bio-Reactor (MBR) membranes
      • Electrodeionization (EDI)
    • Complete water purification systems manufacturing for China

Dow Water Solutions products are used for the full spectrum of water and non-water treatment applications, including industrial water treatment, municipal water treatment, production of ultra pure water, commercial and home drinking water purification, sweetener processing, and other selected specialty applications. They are also used in the purification of foods, pharmaceuticals and other products.

Products by Dow Water Solutions help benefit the health of millions of people, improve the quality and performance of consumer and industrial products, and enable vital industrial processes. Dow is the only global manufacturer of both membrane and ion exchange products, producing FILMTEC™ membrane elements and DOWEX™ ion exchange resins.  Both of these technologies separate dissolved minerals and organics from solutions, producing water that meets the most stringent water purity standards today and achieving the highest quality water with lower operating costs.

In March 2005, Dow launched ADSORBSIA™ GTO™ titanium-based arsenic removal media, a new product based on a Dow proprietary granulation process. The new product offers improved performance and cost advantages in arsenic removal over traditional iron oxide-based adsorbent media. ADSORBSIA arsenic removal media is helping municipalities meet the recent EPA regulation, which went into effect on January 23, 2006, requiring municipal drinking water systems in the United States to have arsenic levels below 10 parts per billion (ppb).

More recently, in June 2006, Dow acquired Zhejiang Omex Environmental Engineering (OEE) Co. Ltd., based in Huzhou, Zhejiang, China, allowing Dow to gain three critical, enabling component technologies for water treatment: Ultrafiltration (UF), Membrane Bio-Reactor (MBR) membranes, and Electrodeionization (EDI), as well as, gaining a complete water purification systems manufacturer for China.

Ultrafiltration (UF) is a pressure-driven membrane separation process that separates particulate matter from soluble components in the carrier fluid (such as water). UF membranes typically have a high removal efficiency for bacteria and most viruses, colloids and silt. The Polyvinylidenefluoride (PVDF) membrane which is part of the UF capability acquired from OEE has the smallest nominal pore diameter in the water treatment industry (for PVDF material) allowing for the removal of all particulate matter, bacteria and most viruses and colloids.

Firmly established as a global leader in reverse osmosis membranes and ion exchange resins, these new technologies allow Dow to offer its customers easier access to these additional components and provide a higher level of integration with its existing membrane and ion exchange resin technologies.

The constant growth of the Dow Water Solutions business, as well as the ongoing scientific innovations in the fields of membrane technology and water purification, demonstrate Dow's continuing commitment to keeping water safe for millions of consumers.
