The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life –from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA™ Denite® technology is treating 450+ MGD in the Bay.
Municipal water services continually utilize improved technologies so that they can offer their customers higher water quality.
An innovative approach to high quality ice production has been adopted by the new Ice Palace in Moscow.
Ammonia is used as a cleaning and bleaching agent in the production of fertilizers, plastics, explosives, and many other products.
Lincoln Electric Systems (LES) recently commissioned a membrane decarbonation system using 3M™ Liqui-Cel™ EXF-14x28 Series Membrane Contactors to remove CO2 prior to their mixed bed deionizers.
Many manufacturing processes, analytical measurements, and other industrial processes that involve aqueous solutions are adversely affected by bubbles in the fluid stream. 3M™ Liqui-Cel™ SP Series Membrane Contactors provide a very simple, cost effective solution to help eliminate bubbles from such processes.
Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.
Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants.
In the food and beverage industry, there is a growing awareness of environmental considerations wherever chemicals are used. In response, companies are trending towards alternative systems that operate with less chemical usage.
A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO₂ inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO₂ to reduce the load on the equipment and improve the water quality.
IMEC (Interuniversity Micro- Electronics Center) in Belgium is Europe's largest independent research center. It focuses on microelectronics, nanotechnology, and enabling design methods and technologies for ICT (Integrated Circuit Technology) systems. IMEC's research runs 3 to 10 years ahead of industrial needs.
Hollywood, Florida’s 55.5 MGD Southern Regional Wastewater Treatment Plant (SRWWTP) treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 MGD of additional reuse on an annual basis.
