Water and Energy nexus
Importance of water … I'm dying of thirst!
- Water is our body lubricant.
- Water controls body temperature.
- Water detoxifies the body.
- Water is carrier of nutrients in our body.
Access to drinking water … an increasing demand.
Lack of access to clean water is a huge problem
768
Million
Living without reliable access to drinkable water
40
Billion
hours per year is spent travelling for water in Africa
85%
of the world population lives in the driest half of the planet
Without clean water people are vulnerable
to death and disease
272
Million
School days are lost every year due to diarrhea
88%
of diarrhea diseases are preventable through access to clean water
6 to 8
Million
people die annually from the consequences of water-related diseases
Water is not just for drinking
Agriculture
uses approximately 70% of the world’s freshwater supply.
Coal power plants consume more than 500 billion L of fresh water per day in the United States alone.
Energy for water …. Water for Energy
- Fuel Production
- Extraction and Refining
- Hydropower
- Thermo-electric cooling
- Waste Water Treatment
- Ground and Surface Water Treatment
- Pumping and Transportation
- Hydropower
Membrane-based processes ... a critical role at the water-energy nexus
Reverse Osmosis
A reverse osmosis membrane is a filter that allows water molecules to pass whilst preventing majority of dissolved salts, organics, bacteria and pyrogens to go through.
Seawater: Source of Energy
A great quantity of renewable energy can be potentially generated when waters of different salinities are mixed together.
