Alpharetta/Georgia – The first commercially-produced gas chlorinator was installed in 1913 by Wallace & Tiernan, now a Siemens Water Technologies company. The technology helped to revolutionise the way the world fought water-borne diseases which killed nearly 30,000 people per year in the 1900s in the United States alone.

The technology is still widely used throughout the world in applications such as waterworks, swimming pools, power generation, sewage treatment, food processing and industrial plants. Siemens Water Technologies' commitment to innovation and industry leadership continues through its research and development focused on ultrapure water and drinking water, waste reduction, energy and process efficiency, desalination and water reuse. Among the current R&D initiatives underway are an advanced desalination technology to greatly increase energy efficiency. The company holds more than 1,800 granted patents and patent applications.

"The use of chlorine in water treatment has arguably done more to safeguard the health of the world than any other development," said Dr. Lukas Loeffler, Siemens Water Technologies CEO. "To this day, chlorination in general is still the most widely used disinfection method internationally and we continue to develop it and other water and wastewater treatment technologies to ensure safe drinking water, clean process water for industry and a healthy environment."
