New model suggests ocean pH falling more rapidly

(Phys.org) -- A new computer model developed in Switzerland shows that the pH of the ocean waters off the west coast of the US will fall over the next four decades faster than previously thought. The region studied is on ...

Vibrio bacteria found in Norwegian seafood and seawater

(PhysOrg.com) -- While working on her doctorate, Anette Bauer Ellingsen discovered potentially disease-causing vibrios (Vibrio cholerae, V. parahaemolyticus and V. vulnificus) in Norwegian seafood and inshore seawater.

From seawater to freshwater with a nanotechnology filter

In this month's Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of water, providing ...

Radical desalination approach may disrupt the water industry

Hypersaline brines—water that contains high concentrations of dissolved salts and whose saline levels are higher than ocean water—are a growing environmental concern around the world. Very challenging and costly to treat, ...

Simple process extracts valuable magnesium salt from seawater

Since ancient times, humans have extracted salts, like table salt, from the ocean. While table salt is the easiest to obtain, seawater is a rich source of different minerals, and researchers are exploring which ones they ...

Desalinating seawater with minimal energy use

At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per ...
