Industries have stringent requirements to control wastewater discharge in the environment to prevent pollution. At the same time, the high volume of water required for processes used in the chemical and petrochemical, pulp and paper, textile, steel and iron, food and beverage industries can make business unsustainable in areas where water availability is limited. Dow technology is helping industries to turn their wastewater streams into a valuable resource by allowing the specific removal of pollutants and treatment of wastewater to high purity standards for reuse in industrial processes, boilers, cooling or utilities.
Recycling and reuse of industrial wastewater is an economical and reliable way to help preserve the environment. The effectiveness of Dow Water & Process Solutions' ion exchange resins and membranes is supported by our own environmental experience operating more than 100 wastewater treatment plants.
