Energy accessibility is at the forefront of many governments and companies’ minds are work is underway to bring energy to those without. One company, Oregon’s Puralytics, is using that energy to help bring clean drinking water to third-world countries.
The company gained international attention several years ago with its SolarBag, a device that used solar energy to clean small amounts of contaminated water, making it safe to drink. Now, with the SolarBag in use in 60 countries worldwide, Puralytics is looking to go bigger.
Water is an essential of life that many of us take for granted. In industrialized countries, we’ve become accustomed to a seemingly endless flow of pure, uncontaminated water from the tap at the turn of a wrist. In our society, access to an unlimited amount of clean water is considered the norm, and as a result we often waste it.
Adelaide engineering students have developed a simple water treatment system using foil chip packets and glass tubing, hoping they can save lives in the developing world. “The system can successfully treat close to 40 litres in four hours and the beauty is that it’s designed to be modular, so more modules can be added for greater quantities of water.”
Water pollution in Russia, according to Greenpeace, continues to be widespread. Recently, however, companies offering new customized solutions for water purification have appeared on the market. One of them was established by former suppliers to Gazprom.
Millions of children can be saved from the ill-effects of fluoride and arsenic contamination in water with the use of a nanoparticle technology patented by a Bangalore University professor.
he plant has been proposed to use reverse osmosis as the primary water treatment process for saline waste water produced by the fracking process at Gloucester
Bill Hunt, executive director of operations for the Orange County Water District, looks out at three large basins of water in Anaheim.
“It’s an aquamarine color. The water is brilliant and clear,” says Hunt. “It’s very inviting. On a warm day, you want to go in it. It’s beautiful water.”
Hunt is not describing a tropical ocean, but recycled sewage.
It’s replenishing the district’s large groundwater aquifer — which is the source of drinking water for 2.4 million people in Orange County.
Nagaland minister for public health engineering department Noke Wangnao inaugurated an innovative water project — solar-powered water treatment unit — at Tsiesema village near Kohima on Friday. Nagaland is the first state in the country to set up the unique technology.
Here’s something to add to your doomsday list of natural resources that people need to survive but are threatened by climate change: snow.
No water bottle? No problem. Ooho, a biodegradable, water balloon-like blob, could soon be a cheap, environmentally friendly alternative to the ubiquitous plastic bottle.
Few people outside of the oil and gas world care about such records, which fill a corner of the university’s Bureau of Economic Geology building that Mr. Ortuño calls his “kingdom.” But those looking to shore up the state’s water supplies are deeply interested. As drought grips most of Texas, researchers are combing the records to map brackish groundwater in the state’s 30 aquifers — hidden resources that could help quench the state’s long-term thirst.
WaterSmart Software, a small startup in San Francisco, is working with local water districts in California and other states to transform meter data into easy-to-understand home water reports that are mailed directly to homeowners or made accessible via the Web and mobile devices.
