Google Uses Recycled Wastewater to Cool Douglas County Data Center
Posted by Ovidiu Sandru in Power Saving, Water Purifiers on March 20, 2012
A new Google initiative wants to recycle wastewater to cool its hot Douglas County, Georgia data center. By collaborating with the local water authority (The Douglas County Water and Sewer Authority – WSA), Google will not only avoid using freshwater for cooling purposes, but will also partially clean the wastewater (30%), thus helping the community use [...]

Microbes and Saltwater Used to Produce Electricity from Wastewater and Waste Heat
Posted by Ovidiu Sandru in Water Purifiers on March 2, 2012
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 [...]

New Nanofiber/Nanotube Material Filters Radioactive Contaminated Water
Posted by Ovidiu Sandru in Nuclear Power, Water Purifiers on November 3, 2011
A new innovation from Professor Huai-Yong Zhu at Queensland’s University of Technology can clean up all the water contaminated by radioactive materials. The material Zhu made is based on nanofibers and nanotubes, and uses an approach that had never been tested before. Titanate nanofiber and nanotubes are the materials he uses, to be more exact. [...]

How to Build a Homemade Water Distiller in Less Than an Hour
Posted by Mircea Sandru in Water Purifiers on August 9, 2011
As one of the most important elements of life, water can cause serious inconveniences when missing. Speaking of potable water, you have to admit that the idea of drinking tap water has become, for many of us, the last alternative. So, instead of drinking tap water, we often buy it from the market. Now, we can’t [...]

Aquacube Water Treatment System Provides Clean Water in Underdeveloped Countries
Posted by Mircea Sandru in Water Purifiers on August 3, 2011
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 earth’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.

NASA Forward Osmosis Bag Transforms Urine Into Drinking Water
Posted by Ovidiu Sandru in Water Purifiers on July 7, 2011
If you ever saw Bear Grylls and his gross pee-drinking desert adventure, then you know you shouldn’t drink that liquid (mostly when it’s hot like soup and stinks like nothing else on Earth). NASA has nevertheless discovered a solution to this “problem” by inventing a bag that filters anything, from pee to dirty water and transforms it into a drinkable liquid.

New Graphite-Coated "Super Sand" Filters Water Much More Efficiently
Posted by Ovidiu Sandru in Water Purifiers on June 28, 2011
With much of the world still lacking access to safe drinking water, the need for more efficient filtration systems is higher than ever. Wei Gao, from Rice University in Texas, has however invented a graphite-coated type of sand that is cheap to produce and much more effective at filtering water.

New Aluminum Alloy Helps Generate Clean Water and Cheap Electricity
Posted by Ovidiu Sandru in Hydrogen Power, Water Purifiers on May 4, 2011
A new aluminum alloy could soon clean out water and at the same time generate electricity for afflicted areas. Purdue University researchers Jerry Woodall and Go Choi have been working on the alloy of aluminum, gallium, indium and tin that could split polluted or salt water into hydrogen and oxygen and then reunite them to generate electricity and pure water.

Clean Water Harvested From Fog by Beetle-Inspired Device
Posted by Mircea Sandru in Green News, New Inventions, Water Purifiers on April 25, 2011
Inspired by Stenocara gracilipes, a beetle found in the Namib Desert, MIT engineer Shreerang Chhatre developed a simple and efficient device that can harvest fog. Being actually an inexpensive way to provide clean drinking water, this fog harvesting device could be perfect for poorer countries, where water scarcity is still an unsolved problem.

Drinkable Water Extracted From Diesel Fuel Now Possible
Posted by Mihai Sandru in Water Purifiers on April 21, 2011
Apparently, necessity teaches us better than any ecological drive, or at least this seems to be the case for the U.S. military. Missions can’t do without water, but the amounts they need are very hard to transport. So the Oak Ridge National Laboratory has found a way to ease the pain of carrying large water supplies.

Contaminated Waters to Be Treated with Forest Debris and Crushed Shells
Posted by Mihai Sandru in Water Purifiers on April 18, 2011
With the risks nuclear reactors are posing in every country, a solution had to be found for waste to be extracted. Thanks to researchers at the University of North Carolina, a material has been found, which on top of everything is 100% natural: forest debris mixed with crushed crustacean shells.
