This video is part of AWWA's Water Supply Operations series on disinfection byproducts. Disinfection is essential in the battle against waterborne disease; however, disinfectants also can create unwanted byproducts. These disinfection byproducts or DBPs are a concern because they can potentially cause long-term health issues. This creates a tough balancing act for utilities: protecting the public from waterborne disease while minimizing the occurrence and impact of DBPs. This video covers the types of disinfectants used in water treatment, how disinfection byproducts form, and strategies to control DBPs, including guidelines set by EPA through the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules.

The negative impacts of man-made CO2 emissions on the environment are already well researched and documented. But the damaging effects of the increasing amounts of carbon dioxide that are ending up in our seas and oceans are less well known. Marine scientists at the IAEA's Environment Laboratories in Monaco are using a range of nuclear and isotopic techniques to study a process known as "Ocean Acidification."

After 15 years of operation, S.A. Industrias Celulosa Aragonesa (SAICA) was faced with the prospect of no longer qualifying for Spain's total feed-in tariff unless it could upgrade its GE 6B gas turbine to meet Spanish environmental regulations. The paper mill upgraded its GE unit with a Flange-to-Flange solution to increase output by 8%, reduce its emissions by more than 90%, and cut the frequency of its required maintenance outages in half.

Honeywell's Sulf-N 26 ammonium sulfate nitrate fertilizer offers the best of all worlds. It is safer to handle, transport, and store, and it is more difficult to alter, making it impractical to use as an explosive agent. Additionally, crop tests show that Sulf-N 26 yields are equal to or better than other fertilizer options available today, which makes it a powerful option for meeting food demand as the population grows.

Gamesa has made progress on its offshore strategy by developing the Gamesa 5.0 MW offshore platform. Based on the proven technology validated in recent years in Gamesa’s 4.5 MW platform and the operating know-how and experience built up, the 5.0 MW offshore platform combines high reliability and optimal cost of energy. In addition to its 5 MW offshore system, Gamesa plans to develop higher-capacity offshore turbines (7 MW-8 MW) in the medium to long term. The G128-5.0 MW Offshore prototype has been equipped with a 128-meter rotor diameter and a modular and redundant design that will ensure reliability and maximizing energy production.

This video describes a solution to the severe health risks caused by mercury emissions from small-scale gold processing. Small scale gold buying and refining facilities, or gold shops, located in more than 55 countries throughout the world, are an important part of the artisanal and small-scale gold production process and are a major cause of air pollution from mercury. EPA and Argonne National Laboratory worked together to design a low-cost mercury capture system that is simple to build and install, using locally available materials. The system reduces mercury emissions by at least 80 percent. For more information about the Mercury Capture System, go to www.epa.gov/international/toxics.

Manila is just one of the world's largest cities that are situated on the water's edge. For these cities the oceans provide jobs, food and opportunities for transportation and recreation. But as pollutants move downhill, they are ending up on the shores and in the seas. Scientists from the Philippine Nuclear Research Institute (PNRI) monitor and manage the pollution in Manila Bay.
