Natural oil adsorbent for produced water treatment
Instead of being just landscaping waste, the dried leaves can help environmental agencies and oil and gas companies treat waste water from petroleum extraction
New generation of water treatment membranes
Due to the increasing amount of contaminants in surface water, such as hormones and medicine residues, it is increasingly difficult to produce clean drinking water in the Netherlands. This requires a new generation of water ...
Nanostructures to facilitate the process to eliminate organic contaminants in water
A researcher at the Public University of Navarre (UPNA) has developed nanostructures that assist in water decontamination. The nanostructures are coated in titanium oxide to which nitrogen has been added. ...
Space brings fresh water to Morocco
Recycling waste water and urine into drinking water is not only for astronauts – the same method is now treating groundwater for a school in Morocco.
High-efficiency water treatment using light using a novel UV-light system
Many harmful substances in waste water stubbornly resist being broken down by biological waste water treatment plants. Fraunhofer researchers have developed a photochemical reaction system in which water ...
Anaerobic treatment of wastewater is a step towards sustainable energy
Until recently, most of the world's energy supplies have come from coal, oil and gas. Scarcity of natural resources, surging energy prices and global warming had focused attention on renewable energy, and consequently, alternative ...
Toilet tech fair tackles global sanitation woes
Who would have expected a toilet to one day filter water, charge a cellphone or create charcoal to combat climate change?
Hunt for water intensifies—on two planets
(Phys.org) —Scientists are using a promising new theory to track down hidden water both on Earth – where fresh water is becoming dangerously scarce in some regions – and in the quest for life on the red planet, Mars.
Researchers recovering metals and minerals from waste
Scarcity of clean water is one of the most serious global challenges. In its spearhead programme, VTT Technical Research Centre of Finland developed energy-efficient methods for reuse of water in industrial processes and ...
Wastewater treatment using microalgae enables phosphorous and nitrogen removal in darkness
Removal of nitrogen and phosphorous from urban waste waters using a simpler and more inexpensive system based on microalgae was the starting point of the research conducted by several UCA scientists of the ...
Wastewater lagoons are potential energy source, researchers say
(Phys.org) —Wastewater treatment lagoons have the potential to serve as a local energy source, according to a Clarkson University doctoral student.
Scientist studies septic systems' effect on water quality
A University of Georgia soil scientist is studying how on-site home septic systems affect the quality and quantity of water in Georgia's rivers and streams.
Starting fire with water
When firefighters want to extinguish a blaze, they often douse it with water. Astronauts on board the ISS, however, are experimenting with a form of water that does the opposite. Instead of stopping fire, ...
Using the potential of waste heat
Siemens researchers analyze how different components of the future energy system can be combined in an optimized way. In its latest issue the research magazine "Pictures of the Future" reports about the chances ...
