#Crowd-sourced computing reveals how to make better water filters with nanotubes Crowd-sourced computing has helped an international research team including researchers from the University of Sydney discover a new method of improving water filtration systems and water quality.

which was able to simulate water flow in carbon nanotubes at very low speeds an activity that would normally require the equivalent of up to 40,000 years of processing power on a single computer.

simulations of water flow in carbon nanotubes could only be carried out under unrealistically high flow-rate conditions says the Director of CNMM, Quanshui Zheng. hanks to World Community Grid,

which will become essential to analyze the massive data generated by the volunteered computers. y simulating water molecules flowing through nanotubes we have shown how vibrations result in oscillating friction,

leading to enhancements in the rate of water diffusion of more than 300 percent. Ultimately this will help design new carbon nanotube based membranes for water filtration with reduced energy consumption. rowd-sourced computing power was essential to the success of our project.

#NEC Conducts Water Leak Detection Trial for the City of Arlington, Texas NEC Corporation, NEC Corporation of America,

and the City of Arlington, Texas, today announced the successful conclusion of a water leak detection trial project for the city.

NEC delivers cutting-edge technology that offers municipal water utility companies a cost-effective way to manage water resources to help meet the water needs of the communities they serve.

and then can be used to identify the locations of water leaks. The project with the city of Arlington is the first of its kind conducted by NEC in the United states. During the course of this project,

Three water leaks were identified during the four months trial and have been repaired. This is the first step for the City to develop a long-term leak detection strategy by evaluating current leak detection technology. he City was pleased with the outcome of this project

says Darryl Westbrook, assistant director of Water Utilities, the City of Arlington. EC is committed to using innovative technology to help strengthen

#Researchers Develop Super-Hydrophobic Metal Surfaces Using Lasers Researchers have turned metal surfaces water repellent using femtosecond laser pulses.

This means that water will just bounce off their surface once it hits it. Chunlei Guo, a physicist at the Institute of Optics at the University of Rochester and the lead author of the study,

said, his is the first time that a multifunctional metal surface is created by lasers that is super-hydrophobic (water repelling),

and can turn saline water palatable by removing its salty taste. MIT Mechanical engineering Phd student Natasha Wright worked for the project over three years to come up with the technology,

which initially focused on filtering biological contaminants from groundwater to make it potable. She joined MIT Mechanical engineering assistant professor Amos Winter's laboratory in 2012,

which uses electric potential to extract salt from the water. The ultraviolet light from the sun rays are used to kill biological contaminants in the water.

While similar desalination technologies have already been discovered, none of the available filters were able to remove the saltiness of the water post-treatment.

During her visits to rural India for the project, Wright found desalination devices were not much use to villagers.

though purified the water, could not eliminate its salty taste. Wright said:""The biggest surprise of the project so far has been this salt issue,

which will have a capacity to offer potable desalinated water for 5, 000 people. Wright and her research team have received a US Agency for International Development (USAID) grant for testing the system at full-scale for the first time in New mexico earlier in the year.

#California State Water Resources Control board adopts new emergency regulations LAGUNA NIGUEL, Calif. New emergency regulations adopted by California State Water Resources Control board (State Water Board) will go into effect June 1, according to a press release.

The regulations are designed to implement Gov. Jerry brown recent call for a 25 percent reduction of statewide water use,

stated the release. The State Water Board has assigned mandatory conservation goals to each urban area based on residential per capita water use to achieve this goal,

continued the release. Urban areas with the highest residential per capita water use are required to conserve more

with reduction goals ranging from eight to 36 percent, reported the release. his announcement solidifies the need to take conservation to the next level.

We are prepared to work with customers to ensure we deliver on the state-required 20 percent water-use reduction,

said Moulton Niguel Water District (MNWD) General manager Joone Lopez. t is now all of our responsibility to conserve as our efforts must collectively tie together to achieve the statewide 25 percent conservation mandate.

MNWD customers have achieved significant reductions in water use, resulting in the lowest annual water usage on record since 1991
