IBM’s World Community Grid helps research to improve water quality

A team of international researchers led by scientist from Tsinghua University in China have used a virtual supercomputer, developed by IBM, to conduct simulations for using nanotechnology in clean water production.

Published in the journal Nature Nanotechnology, the process involves use of carbon nanotubes under specific conditions to enable efficient water filtering at reduced expenses and environmental impact.

IBM’s World Community Grid was used by the researchers led by the Center for Nano and Micro Mechanics at the university to conduct computational simulation study for the process.

GE’s LEAPmbr technology raises capacity of wastewater treatment plant in North Las Vegas, US

US based General Electric has installed its LEAPmbr membrane bioreactor (MBR) technology to upgrade a wastewater treatment facility in the city of North Las Vegas, US.

Post modifications, the plant will be capable of treating municipal wastewater for more than 300,000 residents. It has been equipped to process nearly 25 million gallons of wastewater every day.

Earlier, North Las Vegas had to depend on Las Vegas city for wastewater treatment services.

"The retrofit will give us a 29% energy reduction on membrane aeration and will save more than $100,000 per year in energy and maintenance costs."

In 2012, the city developed the facility featuring GE ZeeWeed membranes and MBR technology. GE’s LEAPmbr technology was deployed at the plant later on, to raise its treatment capacity.
