Test Procedure and Energy Conservation Standard for Pumps
The new standard is expressed as a Pump Energy Index applicable for rotodynamic, clean water pumps used in a variety of commercial, industrial, agricultural, and municipal applications.
Reusable Sponge Soaks Up Oil, Could Revolutionize Oil Spill and Diesel Cleanup
When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered a new wrinkle: the millions of gallons of oil bubbling from the sea floor weren’t all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting through the ocean under the surface.
Black Carbon: A Culprit in Russian Arctic Warming?
Major sources of black carbon – a pollutant implicated for accelerating climate warming trends in the Russian Arctic – include residential heating and transportation.
Winery Improves Water Treatment
A bioelectrically-enhanced treatment solution will process all effluents onsite, and generate electricity and heat, for a California winery.
EHD Pump Cools Space Hardware
A candidate cooling technology developed at Worcester Polytechnic Institute’s will fly aboard the International Space Station later this decade.
Higher Efficiency and Cleaner Air for HVAC
A new HVAC module improves indoor air quality, while reducing the need for outside air.
Clarke Industrial Signs Valve Deal for Major Industries
Curtiss-Wright licenses Shutter Valve technology for several major industries.
Lithium Recovery from Oil Brine
Production time for recovering lithium from heavy oil wastewater is reduced 99% compared with the use of solar evaporation technology.
Hydraulic Fracturing Fluids Change Water Chemistry in Gas Wells
A multidisciplinary team of researchers from Penn State has discovered that pressure, temperature and fluid composition significantly affect the amount of metals and other chemical found in hydrofracking wastewater.
Researchers: Hydraulic Fracturing Boosts Local Economies
The first nationwide study of the comprehensive local impacts of hydraulic fracturing finds that when costs and benefits are added up, communities on average benefit from allowing it.
What to Look For in a Thermal Design Solution
Computational fluid dynamics enable engineers to model thermal responses including all the modes of heat transfer, namely conduction, convection and radiation. The results can be used to judge component and environment design viability.
LevelGuard Pump Switch Passes 3.5 Million Cycles in Test
Four LevelGuard Pump Switches are currently available, including a sewage model, with 9-foot and 15-foot cords that use piggy-back plugs, as well as a 30-foot pigtail cord.
