How U.K., U.S. Teams Optimized Arsenic Removal Process and Media Over Nearly a Decade
The World Health Organization (WHO) recommended in 1993 that the arsenic standard of 50 µg/l be reduced to 10 µg/l. Since then, a variety of arsenic removal systems and media have been developed, and countries throughout the world have been implementing the new standard on varying time tables.
Over nearly a decade, one arsenic removal process and media have been optimized by teams working cooperatively in the United Kingdom and the United States. To learn more about the challenges these teams faced and the solutions they developed, click on the link below.

Microwave Technology: The Future of UV Disinfection
Traditionally, ultraviolet (UV) disinfection technologies available for use in wastewater, drinking water and water reuse applications have used mercury UV lamps containing electrodes for the generation of UV radiation to meet disinfection needs. These electrodes are delicately constructed and their deterioration is the primary source of disinfection system failures.
Click on the link below to read about a groundbreaking development in UV disinfection that utilizes electrodeless, high-output UV lamps integrated with advanced system designs.

World’s Largest Denitrification Plant Helps Tampa Bay Reduce Nutrient Pollution
Nutrient pollution is getting worse in many estuaries throughout the United States, especially those on the heavily populated East Coast. That’s the finding of the National Oceanic & Atmospheric Administration (NOAA) in its July 2007 report, “Effects of Nutrient Enrichment in the Nation’s Estuaries: A Decade of Change.”
Nevertheless, the NOAA report noted that some of the nation’s estuaries have shown significant improvement in reducing nutrients such as phosphorus and nitrogen. To find out about one Florida waterway’s successful nutrient management program, read on.

Competition Comes to U.K. Water Industry
The U.K. water and wastewater market has long been closed to competition. Twenty-two companies currently act as regional suppliers, providing water and sewerage services to populations in specified geographic regions of England and Wales. However, in December 2005, the United Kingdom’s economic regulator of water and wastewater services, Ofwat, introduced competition to the industry with the intent of making customer service and pricing more competitive.

Municipality Surpasses Nitrogen Reduction Goal Well in Advance of EPA’s 2014 Mandate
When the New York State Department of Environmental Conservation (DEC) announced the winners of its second annual New York State Environmental Excellence Awards in late 2005, the City of Glen Cove’s wastewater treatment plant was the only wastewater treatment facility to receive the award. The City was cited by the DEC for its contribution to “environmental innovation, sustainability, and creative partnerships” that helped achieve “unprecedented nitrogen discharge reductions” in Long Island Sound.

Improving Water Management Where Water is Scarce
Situated in the Middle East, Jordan is one of the 10 most water-deprived countries in the world. While the average U.S. citizen has more than 2,377,500 gallons of fresh water available per year, the average Jordanian has around 53,000 gallons per year. Natural population growth combined with periodic influxes of refugees has put a tremendous strain on the limited water resources in the arid, mostly landlocked country.
To learn how the country is dealing with its water management challenges, click on the link below.
