It has been named one of the Seven Modern Wonders of the World with about 14,000 cargo ships passing through its two locks every year. In 2016, its wonder will expand as a third set of locks opens and Post-Panamax ships pass between the Atlantic and Pacific Oceans for the first time.
Those who are philanthropically-minded need look no further for a cause than that of water. After all, this is a fundamental aspect of human existence and one that is shockingly scarce in some parts of the world.
The city of Scottsdale, Arizona, a community of more than 200,000 residents was historically totally dependent on groundwater resources. By the mid 1980’s, the city began putting together a multi-faceted water resource program to provide the community with a long-term sustainable water supply.
Looking to reduce potential disinfection byproducts issues that new and difficult regulations were requiring, a Tennessee municipality began investigating alternative water treatment disinfection methods in an effort to reduce the potential liability (RMP) involved with using and storing gas chlorine. Within months of switching to a mix of oxidants (MOS), a difference was noted in the systems residual, residual was no longer dead spotting in low flow areas, and much higher residual was noted in areas that had been difficult to maintain At the end of the first year of operation the municipality had also documented a reduction in their disinfection byproducts formations, specifically both TTHMs and HAAs, which were both reduced by 50% in direct comparison with the quarterly results from the previous year.
In certain applications, conventional grounding of electromagnetic flowmeters can pose special challenges. This article illustrates those challenges and sheds light on a unique solution that is especially suitable for problematic applications, some of which are found in desalination facilities.
The Georgia Aquarium system operates as a closed loop and is able to recapture and reuse over 99% of the water in its exhibits. In order to reuse the majority of the tank water, the aquarium must ensure that waste from its aquatic residents is removed.
In the wastewater treatment industry, coagulation has become one of the most widespread processes for effectively separating contaminants and effluent. But coagulation is a complicated and sensitive process, one that alters the chemical balance of the wastewater in order to strip it of unwanted constituents. As in many such processes, pH plays a critical role, and treatment professionals must analyze it closely if they want to properly coagulate their product.
