Composite Nanomaterials Remove Microbes and Chemical Contaminants From Drinking Water

Posted by Mila Luleva in Water Purifiers on May 8, 2013

A prototype developed by researchers at the Indian Institute of Technology Medras in Chennai, India, purifies 10 litres of water at a time, making it free from harmful contaminants and bacteria. The study was published in the latest issue of the journal Proceedings of the National Academy of Sciences. It shows how a mixture of [...]

Nano Device Based on AcrB Protein Offers Solar-Powered Water Filtering

Posted by Ovidiu Sandru in Water Purifiers on April 24, 2013

A new nano-filter powered by sunlight can clean large bodies of water from antibiotics and carcinogens. The device, developed by the University of Cincinnati, is much more effective than the activated carbon that’s currently being used for this purpose. Two bacterial proteins absorb about 64 percent of the antibiotics in surface water. For a comparison, [...]

New Nanomaterial Purifies Water, Produces Energy And Improves Lithium-Ion Batteries

Posted by Mila Luleva in New Inventions, Solar Power, Water Purifiers on March 21, 2013

Generating hydrogen, producing and desalinating water and creating energy are just some of the properties of a brand new nanomaterial, developed by scientists at Nanyang Technological University (NTU) in Singapore. The Multi-use Titanium Dioxide (TiO2) was invented by the Associate Professor, Darren Sun and his team in a five-year long study. The material is cheap [...]

Perforene: A Graphene Water Filter 100 Times More Efficient

Posted by Benji Jerew in Water Purifiers on March 13, 2013

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

Lima, Perú – Freshwater From a Billboard, University of Engineering and Technology

Posted by Benji Jerew in Green Designs, Water Purifiers on February 27, 2013

If there’s one thing that mars a skyline worse than a building in front of your favorite mountaintop, it’s probably a billboard. Of course, a billboard is put there in your face for exactly that reason, so you take notice of it. In Lima, Perú, the University of Engineering and Technology [UTEC] has re-imagined the [...]

Toxins Removed from Water by New Metal-Organic Framework

Posted by Leigh Kim in Water Purifiers on January 24, 2013

A new Metal Organic Framework (MOF) may have the ability to filter environmental toxins out of water, thanks to a team of scientists at Monash University at CSIRO who developed it. MOFs are comprised of clusters of atoms that are connected by organic molecules. MOFs have identically sized pores, making it very easy to capture and [...]

Chlorinator Water Treatment System for Developing Countries Developed by GE Engineer

Posted by Benji Jerew in Water Purifiers on January 12, 2013

One of the most basic human needs is clean drinking water, which for millions of people in developing countries is simply not available. Without access to clean water, the population is vulnerable to water-borne diseases, something as simple as dysentery killing thousands every year. Unfortunately, getting clean water to these people is often expensive and [...]

Graphene Oxide Offers New Hope for Water Decontamination

Posted by Benji Jerew in Pollution, Water Purifiers on January 9, 2013

Water is the universal solvent on the planet, and without it, minerals and nutrients can’t be transported. Life would cease to exist. This property of water, though, means it also transports and disperses toxins just as easily, including radioactive materials. Cleanup around nuclear sites, such as the recent disaster at the Fukushima Daiichi nuclear power [...]

Improved Filter for Treating Olive-Processing Wastewater

Posted by Benji Jerew in Power Saving, Water Purifiers on December 24, 2012

Olives and olive oil have been touted for centuries as part of a healthy diet, benefits including lowering blood pressure and the risk of heart disease, as well as defense against certain types of cancer. In order for these products to make it to your table, though, a certain amount of processing is required, which [...]

14 Year-Old Invents Cheap Solar Powered Water Purification System

Posted by Mike Sandru in Solar Power, Water Purifiers on December 18, 2012

As teenagers, most of us cared more about say, a humiliating acne outbreak or which classmate we’d ask to homecoming, rather than the difficulties of developing countries. When she watched some Indian children drinking from a pool of stagnant water, Deepika Kurup, a 14-year-old living in Nashua, New Hampshire made it her goal to help [...]

Severe Water Crisis Could Hit the World by 2025 (Infographic)

Posted by Ovidiu Sandru in Green News, Water Purifiers on December 6, 2012

When you wash your car, when you extend that already extra-long shower or simply when you flush the toilet, think for a moment that you won’t be able to do it as cheap and as easily only a decade from now. The world’s water resources are on a downward-facing slope, and there’s much we can [...]

Water Purification Sachets to Aid Developing Countries

Posted by Janina Lazo in Water Purifiers on November 30, 2012

With the aim to provide developing countries a cheap and easy way to purify water, Procter and Gamble (P&G), a giant multinational consumers good company, has developed a small water purification system packed in small sachets called ‘Pur’. Each sachet can purify 10 liters of brown, murky water into clear and drinkable water, enough for [...]

Coca-Cola and Dean Kamen Partner for Clean Water

Posted by Benji Jerew in Water Purifiers on November 29, 2012

One of the world’s growing problems, not only in developing countries, is access to clean drinking water. Over ¾ billion people could benefit from a partnership between Coca-Cola Corporation and Dean Kamen, the inventor of the Segway. Kamen’s company DeKa, also holds patents on stirling engine designs, the AutoSyringe drug infusion pump, and even an [...]

Phosphine-Functionalized Resins Capturing Gold From Wastewater

Posted by Janina Lazo in Green News, Water Purifiers on October 31, 2012

The extraction of toxic but valuable metals such as nickel, chromium, lead, and mercury, from wastewaters produced in various industries such as semiconductor and mining has been a serious challenge to these industries. Unlike the commonly used ion-exchange resins that bind with metals unspecifically, a newly developed phosphine-functionalized resins bind with metals selectively via coordination [...]

A Novel Water Treatment Method Using Simple Electrochemistry

Posted by Janina Lazo in Water Purifiers on October 27, 2012

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 [...]
