How Ceramic Water Filters Save Lives in World’s Most Polluted Rural Areas

Mila Luleva — Fri, 03 Jan 2014 19:42:26 +0000

Access to clean drinking water in many parts of the world is what determines whether a life can be saved or lost. This is especially the case in parts of Africa, where the levels of pollution are way above any regulatory limits, while income is so low that even the cheapest water purification mean seems […]

Wastewater Treatment Could Have Huge Impact for Emerging Economies

Mila Luleva — Fri, 06 Sep 2013 14:16:59 +0000

Treating and recycling wastewater might be the key to solving the water scarcity problem in many countries around the world, according to new research from Japan’s Tottori University and U.N. University’s Canadian-based Institute for Water, Environment and Health (UNU-INWEH). Although the price of new treatment facilities is said to be the main reason to why […]

Porous Gel Made of Silver Nanoparticles Provides Solution to Drinking Water Shortage

Mila Luleva — Mon, 26 Aug 2013 18:18:34 +0000

A team of scientists from Nanyang Technological University and University of Colorado developed a method to purify contaminated water using silver nanoparticles. The technology, unlike any of the existing ones, is cheap, fast, effective, and does not require any electricity. The work was published in the latest issue of the journal Environmental Science and Technology. […]

Sweat Turned to Potable Water in UNICEF Campaign

Mila Luleva — Fri, 19 Jul 2013 07:28:15 +0000

An incredible sweat-extraction machine, which takes the moisture from sweat-laden clothes and turns it into fresh drinking water, is built in Sweden and used to promote a campaign by Unicef. The invention filters out the bacteria, salt and fibres from the clothing, and lets only the water molecules in the form of steam to pass […]

Perforene: A Graphene Water Filter 100 Times More Efficient

Benji Jerew — Wed, 13 Mar 2013 16:03:20 +0000

True, the technology is a couple years away, but graphene-based Perforene developed by Lockheed could revolutionize desalination and water purification. Lack of freshwater is becoming an increasingly desperate situation, typical desalination is energy intensive and expensive, but a graphene water filter could be 100x more efficient. Graphene, a nanoscale material made up of pure carbon, […]

A Novel Water Treatment Method Using Simple Electrochemistry

Janina Lazo-Cruz — Sat, 27 Oct 2012 06:25:32 +0000

Various water treatment systems have sprung up to increase the quality of drinking water. For remote and underdeveloped areas, unfortunately, these technologies are not within reach. This situation led two chemists to a simple, yet brilliant idea to transform bore water into a potable one. Through electrochemistry, Dr. Hilary Nath and Associate Professor Alan Langdon […]

Graphene Membranes Could Aid Water Filtering

Mila Luleva — Wed, 24 Oct 2012 17:16:40 +0000

Graphene has proven itself as not only a great conductor for heat and electricity, but also a perfect substance for a barrier film and bullet repellent. However, researchers from MIT, Oak Ridge National Laboratory, have discovered that although the material seems impenetrable, by building large membranes from single sheets of graphene grown by chemical vapour deposition, small […]

Microbes and Saltwater Used to Produce Electricity from Wastewater and Waste Heat

Ovidiu Sandru — Fri, 02 Mar 2012 18:15:21 +0000

The difference between saltwater and freshwater can produce electricity. Microbial fuel cells use bacteria to degrade organic matter to also produce energy. Great as they are, these two technologies have had limitations in the past, but now a team of scientists unite them in a system that eliminates most of their shortcomings. The team, led […]

Aquacube Water Treatment System Provides Clean Water in Underdeveloped Countries

Mircea Sandru — Wed, 03 Aug 2011 14:25:20 +0000

Water, a key element of life, has always been one of the most exploited natural resources. Even if we have a lot of water (71 percent of the earthÃ¢â‚¬â„¢s surface), in some places on earth drinking water still remains an unsolved issue. Especially with the increasing population and industrial development, our clean water resources dropped drastically in recent years.
