As fracking amongst Marcellus Shale in the northeastern part of the United States increases so does the concern over its process. Fracking is done utilizing a hydraulic fracturing process, which pumps a high-pressure mixture of water, chemicals and sand deep into the sedimentary formations to extract naturally occurring gas. The resultant (more…)
Researchers found high levels of radioactivity, metals, and salts in sediments and water downstream from a Pennsylvania facility that treats fracking wastewater. Radioactivity levels downstream of the treatment plant were about 200 times higher than in surrounding areas, and concentrations of some salts and metals were also higher than background levels, (more…)
Seeds and oils from the plant that produces the loofah sponge could help purify wastewater and prevent the spread of waterborne diseases in the developing world, according to a scientist speaking today at the 17th Annual Green Chemistry & Engineering Conference in Bethesda, Md. The low-cost, biodegradable seeds and substances made from oils of these seeds (more…)
“There is a an almost uncanny fit between India’s needs in the urban water arena, and what Israeli companies are able to offer,” so says Abraham Tenne, VP Desalination at Israel’s Water Authority following a visit last week to India. The visit was one implementation of an agreement signed this past February between the two nations aimed at fostering cooperation, with a (more…)
Not many cleantech start-ups can claim a 40 million dollar deal only a year and a half after founding. But WateRevive, which was selected as one of the most promising Israeli cleantech start-ups by Calcalist newspaper in 2012, and which is active in water purification through constructed wetland, just closed such a deal in China. The Company is also (more…)
Carbon emissions that go into the atmosphere are the pivot of environmental talks, and for a good reason, since they are the main cause of global warming (switching to alternative energy is one of the solutions to that). There are lots of earth-level environmental issues that need to be dealt with urgently such as water treatment and some people (more…)
For its July magazine issue, Texas Monthly took an in-depth look at the diminishing Texas water supply. The detailed cover story jumps right to the heart of the matter in the first paragraph: “As last year’s historic drought reminded us, Texas has always lived life by the drop, just a few dry years away from a serious crisis. With our population expected to nearly double (more…)
Water and wasterwater facilities in California, Arizona and Nevada will be enjoying the benefits of solar power thanks to a new partnership struck with Kennedy/Jenks. Water treatment is an energy-hungry method, therefore introducing clean, renewable energy can reduce its environmental footprint. (more…)
NASA has developed a system capable of growing large amounts of algae for biofuel production within a network of floating plastic bags, an innovation its developers say could ultimately produce a new fuel source.
U.S. scientists have developed a fuel cell capable of converting 13 percent of the energy found in sewage into electricity, a process that its developers say could also more efficiently treat municipal wastewater.
In a report released at the annual meeting of the American Chemical Society, researchers at the J. (more…)
