Companies report annual savings of 1 billion gal of water and at least $4 million in maintenance at one Dow plant
Nalco, providing solutions for water, energy and air, and The Dow Chemical Co. announced that their cooperative efforts have resulted in annual water savings of 1 billion gal of freshwater at Dow’s Freeport, Texas, production site. That’s enough water to supply nearly 40,000 people in the U.S. for one year, the companies said.
Dow implemented Nalco’s 3D TRASAR Technology for Cooling Water to treat the 80 process and comfort cooling tower systems for the 5,000-acre site after designating it a Dow MET (Most Effective Technology). A Nalco/Dow team adapted the 3D TRASAR technology using Six Sigma methodology to classify cooling tower systems based on 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 CEO. “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.”
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, the companies said.
