DuPont’s Dordrecht Facility Reduces Fresh Water Consumption with GE’s Advanced Water Treatment Technology

Posted: Tuesday 28th June 2011

Plant Reduced Fresh Water Intake by 91,000 m3 per Year, the Equivalent to the Amount of Water Consumed by 650 Average Dutch Households.

GE’s advanced water treatment technology has helped DuPont achieve significant improvements in water conservation efforts at its Dordrecht facility in the Netherlands, one of the biggest DuPont production plants in Europe.

Through a comprehensive water management assessment, GE found opportunities to help DuPont’s Dordrecht plant decrease the plant’s water footprint by improving efficiency at the site’s cooling tower. Cooling water systems are essential to production in many industrial plants, including chemical processing facilities, and they can require a considerable amount of water to run. Maintaining cooling system efficiency to manage costs and minimize water footprint is a critical aspect of any industrial operation.

By implementing a comprehensive water treatment program that included advanced GenGard chemistry and a sophisticated dosing system, GE reduced chloride concentration in the intake cooling water, almost doubling overall system efficiency. This increase in efficiency allowed the plant to reduce fresh water intake by 91,000 m3 per year, achieving a 20 percent reduction in water usage in the cooling water, the equivalent to the amount of water consumed by 650 average Dutch households.

“The project is in line with DuPont’s sustainability efforts that include a commitment to reducing water consumption by at least 30 percent over the next 10 years at manufacturing sites where fresh water supply is either scarce or limited,” said Gordon P. Tait, site manager of DuPont Dordrecht. “In addition to supporting our sustainability goals, this technology will allow us to run a more efficient operation and will help us protect critical assets from corrosion, deposition and biological fouling.”

In addition to water reduction, the project improved safety at the site by reducing acid deliveries by truck from 130 to only 15 per year. This also has a positive impact by reducing CO2 emissions. GenGard, the chemical technology at the center of the solution, offers the capability to use lower-quality water in the cooling process while avoiding corrosion and fouling problems. This provides savings in operating costs and improves the efficiency of the cooling system, which results in greater production output, water conservation and the ability to use alternative water sources.

GE has awarded DuPont an ecomagination Leadership Award to recognize the company for its noteworthy reductions in water consumption, chemicals and waste using GE technology. This is the second time this DuPont facility received such a distinction. GE’s ecomagination Leadership Award recognizes the achievements of industrial users that significantly surpass and improve environmental and industrial operational goals while balancing industrial demands.

“We are pleased to present DuPont with an ecomagination Leadership Award for its commitment to sustainable water usage,” said Jeff Fulgham, chief sustainability officer—water and process technologies for GE Power & Water. “DuPont’s commitment shows that increasingly what's good for the environment also can be good for business. With a bottom line financial return to DuPont of $175,000 from this project, the company proved that water conservation also can have a positive impact on operational costs. The company's pioneering leadership has set an example for others to aspire to and follow.”
