Providing , high-performance water filter liquid purification technologi with Unmatched water filter performance, (ultrafiltration 0.04 micron).
UltraHydra can be used for supplying potable drinking water from various sources including wells, dams, creeks, rivers swamps and poor quality town water supplies.
The United Nations has called drought the “world’s costliest natural disaster,” both financially, imposing an annual cost of $6-8 billion, and in human terms; since 1900, it has affected two billion people, leading to m
A hallmark of InfoWorks ICM is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in rivers, open channels and pipe networks and two-dimensional (2D) hydrodynamic simulation of surface flooding in the urban environment and river floodplain.
More than 70% of the Earth's surface is covered in water, but only 0.01% of that water is fit to drink. And the world's population is growing, along with the need for water. Between 2000 and 2025, the world's water consumption is forecast to rise by about 30%.
Now scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.
Innovator Dr. Dudley Jackson developed a waterless toilet for rural areas and temporary settlements that separates liquids from solids to improve environmental impact, decrease the potential for disease, reduce odour and ensure easier removal.
First generation biofuels, like corn ethanol, haven't fulfilled their promise of displacing fossil fuels in a green, carbon neutral way. It's because they require a lot of energy to produce and use food crops, competing with people and animals for that supply, driving prices up and putting pressure on farmland.
With ongoing climate change and contaminated groundwater causing major rifts in water sustainability, nations are beginning to look into alternative water solutions. One startup, PHOG Water, has prototyped a net, based on ancient technology first crafted by the Incas, that harvests water from fog.
Current methods of detecting pollutants in water are costly, time-consuming and require specialist technical expertise. However researchers from the University in collaboration with Bristol Robotics Laboratory at the University of the West of England, have created a low cost sensor using 3D printing technology that can be used directly in rivers and lakes for continuous water quality monitoring.
The synthetic diamond supermaterial has the highest known resistance to thermal shock, a very low coefficient of friction and can be used for ultra-precision machining of metals, polymers and optical materials.
