Alcoa (NYSE: AA) has entered into an agreement with Germany-based engineering and construction company, Bauer Resources GmbH, to commercialize Alcoa’s Natural Engineered Wastewater Treatment technology that mimics natural wetlands to sustainably treat wastewaters. Under the agreement, Bauer will use Alcoa’s engineered wetlands technology to deploy wastewater treatment systems globally.
Alcoa has been engaged in engineered wetlands technology development and deployment at various Alcoa locations for the last 10 years, with the most recent and largest being a system implemented in the Kingdom of Saudi Arabia at the Ma’aden-Alcoa joint venture project site. There, the technology will reduce the facility’s water demand by two million gallons a day, saving $7 million a year in water purchase costs for the integrated aluminum complex.Alcoa’s Natural Engineered Wastewater Treatment system comprises three steps: (1) an anaerobic treatment tank that removes metals and breaks down and separates organic material in the water; (2) a passive engineered wetland that utilizes vegetation for further treatment of organics and removal of nitrogen; and (3) a cell housing bauxite-based technology that disinfects and polishes the water. The result is water treated to the same or better quality as that of a conventional system. About Alcoa Alcoa is the world’s leading producer of primary aluminum, fabricated aluminum and alumina.
