Cooperation Between Nalco and Dow Yields Annual Savings of One Billion Gallons of Water and at least $4 Million in Maintenance at Dow Plant

Nalco announced today their cooperative efforts have resulted in annual water savings of one billion gallons of freshwater at Dow’s massive Freeport, Texas production site. That’s enough water to supply nearly 40,000 people in the U.S. for one year.

Dow implemented Nalco’s innovative 3D TRASAR® Technology for Cooling Water to treat the 80 process and comfort cooling tower systems for the sprawling 5,000-acre site after designating it a Dow MET (Most Effective Technology). A Nalco/Dow team adapted the award winning 3D TRASAR technology using Six Sigma methodology to classify cooling tower systems based on a variety of control parameters to optimize operations.

“Working with our customers is a key part of our product innovation and improvement process,” said J. Erik Fyrwald, Nalco Chairman and Chief Executive Officer. “Developing the innovative solutions that help our customers save water and energy and protect the air can’t happen without key customers like Dow allowing us to refine our technologies in real world situations at their sites.”

“Dow provides some of the basic building blocks for the chemistry the 3D TRASAR system uses to achieve these water savings at Freeport and other Nalco customer locations around the world,” said Gary Hockstra, vice president and Site Leader of Dow’s Freeport operations. “The collaborative efforts used at Freeport were built on our longstanding supplier/customer relationship to provide a leading-edge solution that benefits both companies while contributing to our 2015 Sustainability goals.”

“Responsible operations are a pillar of our commitment to sustainability,” said Neil Hawkins, Dow’s vice president of Sustainability and EH&S. “Dow’s commitment to addressing the global water crisis includes game-changing technologies, partnerships in strategic regions, and collaboration with industry leaders like Nalco to reduce our own environmental footprint.”

3D TRASAR Cooling Water Technology has been recognized with a United States Presidential Green Chemistry Challenge Award. More than 10,000 3D TRASAR cooling water automation units at customer sites around the world allowed customers to save more than 75 billion gallons of water in 2009. 3D TRASAR technology automatically maintains optimal chemistry of the water used in cooling systems, greatly reducing the quantity of water needed, maximizing the efficiency of the processes and reducing the energy necessary to run them. At the Dow Freeport facility it all translates into a $4 million per year reduction in maintenance costs, reduced energy cost, reduced water use and reduced greenhouse gas emissions – which makes it good for the environment and good for business.
